+# QMK Breaking Change - 2020 Feb 29 Changelog
+
+Four times a year QMK runs a process for merging Breaking Changes. A Breaking Change is any change which modifies how QMK behaves in a way that is incompatible or potentially dangerous. We limit these changes to 4 times per year so that users can have confidence that updating their QMK tree will not break their keymaps.
+
+
+## Update ChibiOS/ChibiOS-Contrib/uGFX submodules
+
+* General Notes
+    * A `make git-submodule` may be required after pulling the latest QMK firmware code to update affected submodules to the upgraded revisions
+    * Enabling link-time-optimization (`LINK_TIME_OPTIMIZATION_ENABLE = yes`) should work on a lot more boards
+* Upgrade to ChibiOS ver19.1.3
+    * This will allow QMK to update to upstream ChibiOS a lot easier -- the old version was ~2 years out of date. Automated update scripts have been made available to simplify future upgrades.
+    * Includes improved MCU support and bugfixes
+    * ChibiOS revision is now included in Command output
+    * Timers should now be more accurate
+* Upgrade to newer ChibiOS-Contrib
+    * Also includes improved MCU support and bugfixes
+    * ChibiOS-Contrib revision is now included in Command output
+* Upgrade to newer uGFX
+    * Required in order to support updated ChibiOS
+
+
+## Fix ChibiOS timer overflow for 16-bit SysTick devices
+
+* On 16-bit SysTick devices, the timer subsystem in QMK was incorrectly dealing with overflow.
+    * When running at a 100000 SysTick frequency (possible on 16-bit devices, but uncommon), this overflow would occur after 0.65 seconds.
+* Timers are now correctly handling this overflow case and timing should now be correct on ChibiOS/ARM.
+
+
+## Update LUFA submodule
+
+* Updates the LUFA submodule to include updates from upstream (abcminiuser/lufa)
+* Includes some cleanup for QMK DFU generation
+
+
+## Encoder flip
+
+* Flips the encoder direction so that `clockwise == true` is for actually turning the knob clockwise
+* Adds `ENCODER_DIRECTION_FLIP` define, so that reversing the expected dirction is simple for users.
+* Cleans up documentation page for encoders
+
+
+## Adding support for `BACKLIGHT_ON_STATE` for hardware PWM backlight
+
+* Previously, the define only affected software PWM, and hardware PWM always assumed an N-channel MOSFET.
+* The hardware PWM backlight setup has been updated to respect this option.
+* The default "on" state has been changed to `1` - **this impacts all keyboards using software PWM backlight that do not define it explicitly**. If your keyboard's backlight is acting strange, it may have a P-channel MOSFET, and will need to have `#define BACKLIGHT_ON_STATE 0` added to the keyboard-level `config.h`. Please see the PR for more detailed information.
+
+
+## Migrating `ACTION_LAYER_TAP_KEY()` entries in `fn_actions` to `LT()` keycodes
+
+* `fn_actions` is deprecated, and its functionality has been superseded by direct keycodes and `process_record_user()`
+* The end result of removing this obsolete feature should result in a decent reduction in firmware size and code complexity
+* All keymaps affected are recommended to switch away from `fn_actions` in favour of the [custom keycode](https://docs.qmk.fm/#/custom_quantum_functions) and [macro](https://docs.qmk.fm/#/feature_macros) features
+
+
+## Moving backlight keycode handling to `process_keycode/`
+
+* This refactors the backlight keycode logic to be clearer and more modular.
+* All backlight-related keycodes are now actioned in a single file.
+* The `ACTION_BACKLIGHT_*` macros have also been deleted. If you are still using these in a `fn_actions[]` block, please switch to using the backlight keycodes or functions directly.
+
+
+## Refactor Planck keymaps to use Layout Macros
+
+* Refactor Planck keymaps to use layout macros instead of raw matrix assignments
+* Makes keymaps revision-agnostic
+* Should reduce noise and errors in Travis CI logs
+
+
+## GON NerD codebase refactor
+
+* Splits the codebase for GON NerD 60 and NerdD TKL PCBs into two separate directories.
+* If your keymap is for a NerD 60 PCB, your `make` command is now `make gon/nerd60:<keymap>`.
+* If your keymap is for a NerD TKL PCB, your `make` command is now `make gon/nerdtkl:<keymap>`.

+Four times a year QMK runs a process for merging Breaking Changes. A Breaking Change is any change which modifies how QMK behaves in a way that is incompatible or potentially dangerous. We limit these changes to 4 times per year so that users can have confidence that updating their QMK tree will not break their keymaps.
+
+The list of changes follows.
+
+
+## Core Changes
+
+### Converting V-USB usbdrv to a submodule
+
+[#8321](https://github.com/qmk/qmk_firmware/pull/8321) and [qmk_compiler#62](https://github.com/qmk/qmk_compiler/pull/62).
+
+These PRs move the V-USB driver code out of the qmk_firmware repository and into a submodule pointed at https://github.com/obdev/v-usb. This will make it easier to update the codebase if needed, while applying any potential QMK-specific modifications by forking it to the QMK GitHub organization.
+
+### Unify Tap Hold functions and documentation
+
+[#8348](https://github.com/qmk/qmk_firmware/pull/8348)
+
+Updates all of the per key tap-hold functions to pass the `keyrecord_t` structure, and include documentation changes.
+
+Any remaining versions or code outside of the main repo will need to be converted: 
+| Old function                                         | New Function                                                              |
+|------------------------------------------------------|---------------------------------------------------------------------------|
+|`uint16_t get_tapping_term(uint16_t keycode)`         |`uint16_t get_tapping_term(uint16_t keycode, keyrecord_t *record)`         |
+|`bool get_ignore_mod_tap_interrupt(uint16_t keycode)` |`bool get_ignore_mod_tap_interrupt(uint16_t keycode, keyrecord_t *record)` |
+
+### Python Required In The Build Process
+
+[#9000](https://github.com/qmk/qmk_firmware/pull/9000)
+
+This is the last release of QMK that will work without having Python 3.6 (or later) installed. If your environment is not fully setup you will get a warning instructing you to set it up.
+
+After the next breaking change you will not be able to build if `bin/qmk hello` does not work.
+
+### Upgrade from tinyprintf to mpaland/printf
+
+[#8269](https://github.com/qmk/qmk_firmware/pull/8269)
+
+- Provides debug functionality on ChibiOS/ARM that is more compliant than previous integrations.
+- Less maintenence, fewer QMK customisations, and allows QMK to sidestep previous compile and runtime issues.
+- A `make git-submodule` may be required after pulling the latest QMK Firmware code to update to the new dependency.
+
+### Fixed RGB_DISABLE_AFTER_TIMEOUT to be seconds based & small internals cleanup
+
+[#6480](https://github.com/qmk/qmk_firmware/pull/6480)
+
+- Changes `RGB_DISABLE_AFTER_TIMEOUT` to be based on milliseconds instead of ticks.
+- Includes a code cleanup, resulting in a savings of 100 bytes, depending on features used.
+- Fixed issues with timeouts / suspending at the wrong time not turning off all LEDs in some cases.
+
+The `RGB_DISABLE_AFTER_TIMEOUT` definition is now deprecated, and has been superseded by `RGB_DISABLE_TIMEOUT`. To use the new definition, rename `RGB_DISABLE_AFTER_TIMEOUT` to `RGB_DISABLE_TIMEOUT` in your `config.h` file, and multiply the value set by 1200.
+
+Before: `#define RGB_DISABLE_AFTER_TIMEOUT 100`  
+After: `#define RGB_DISABLE_TIMEOUT 120000`
+
+### Switch to qmk forks for everything
+
+[#9019](https://github.com/qmk/qmk_firmware/pull/9019)
+
+Fork all QMK submodules to protect against upstream repositories disappearing.
+
+### code cleanup regarding deprecated macro PLAY_NOTE_ARRAY by replacing it with PLAY_SONG
+
+[#8484](https://github.com/qmk/qmk_firmware/pull/8484)
+
+Removes the deprecated `PLAY_NOTE_ARRAY` macro. References to it are replaced with `PLAY_SONG`, which references the same function.
+
+### fixing wrong configuration of AUDIO feature
+
+[#8903](https://github.com/qmk/qmk_firmware/pull/8903) and [#8974](https://github.com/qmk/qmk_firmware/pull/8974)
+
+`audio_avr.c` does not default to any pin; there has to be a #define XX_AUDIO in config.h at some level for Audio to actually work. Otherwise, the Audio code ends up cluttering the firmware, possibly breaking builds because the maximum allowed firmware size is exceeded.
+
+These changes fix this by disabling Audio on keyboards that have the feature misconfigured, and therefore non-functional.
+
+Also, add a compile-time error to alert the user to a missing pin-configuration (on AVR boards) when `AUDIO_ENABLE = yes` is set.
+
+
+## Keyboard Refactors
+
+### Migrating Lily58 to use split_common
+
+[#6260](https://github.com/qmk/qmk_firmware/pull/6260)
+
+Modifies the default firmware for Lily58 to use the `split_common` library, instead of including and depending on its own set of libraries for the following functionality:
+
+- SSD1306 display
+- i2c for OLED
+- Serial Communication
+
+This allows current lily58 firmware to advance with updates to the `split_common` library, which is shared with many other split keyboards.
+
+#### To migrate existing Lily58 firmware:
+
+[Changes to `config.h`](https://github.com/qmk/qmk_firmware/pull/6260/files#diff-445ac369c8717dcd6fc6fc3630836fc1):
+- Remove `#define SSD1306OLED` from config.h
+
+
+[Changes to `keymap.c`](https://github.com/qmk/qmk_firmware/pull/6260/files#diff-20943ea59856e9bdf3d99ecb2eee40b7):
+- Find/Replace each instance of `#ifdef SSD1306OLED` with `#ifdef OLED_DRIVER_ENABLE`
+- The following changes are for compatibility with the OLED driver. If you don't use the OLED driver you may safely delete [this section](https://github.com/qmk/qmk_firmware/blob/e6b9980bd45c186f7360df68c24b6e05a80c10dc/keyboards/lily58/keymaps/default/keymap.c#L144-L190)
+- Alternatively, if you did not change the OLED code from that in `default`, you may find it easier to simply copy the [relevant section](https://github.com/qmk/qmk_firmware/blob/4ac310668501ae6786c711ecc8f01f62ddaa1c0b/keyboards/lily58/keymaps/default/keymap.c#L138-L172). Otherwise, the changes you need to make are as follows (sample change [here](https://github.com/qmk/qmk_firmware/pull/6260/files#diff-20943ea59856e9bdf3d99ecb2eee40b7R138-R173))
+- [Remove](https://github.com/qmk/qmk_firmware/pull/6260/files#diff-20943ea59856e9bdf3d99ecb2eee40b7L138-L141) the block
+```c
+#ifdef SSD1306OLED	
+  iota_gfx_init(!has_usb());   // turns on the display	
+#endif
+```
+- Within the block bounded by `#ifdef OLED_DRIVER_ENABLE` and `#endif // OLED_DRIVER_ENABLE`, add the following block to ensure that your two OLEDs are rotated correctly across the left and right sides:
+```c
+oled_rotation_t oled_init_user(oled_rotation_t rotation) {
+  if (!is_keyboard_master())
+    return OLED_ROTATION_180;  // flips the display 180 degrees if offhand
+  return rotation;
+}
+```
+- Remove the functions `matrix_scan_user`, `matrix_update` and `iota_gfx_task_user`
+- Find/Replace `matrix_render_user(struct CharacterMatrix *matrix)` with `iota_gfx_task_user(void)`
+- Find/Replace `is_master` with `is_keyboard_master()`
+- For each instance of `matrix_write_ln(matrix, display_fn())`, rewrite it as `oled_write_ln(read_layer_state(), false);`
+- For each instance of `matrix_write(matrix, read_logo());`, replace with `oled_write(read_logo(), false);`
+
+### Refactor zinc to use split_common
+
+[#7114](https://github.com/qmk/qmk_firmware/pull/7114) and [#9171](https://github.com/qmk/qmk_firmware/pull/9171)
+
+* Refactor to use split_common and remove split codes under the zinc/revx/
+* Add - backlight RGB LED and/or underglow RGB LED option
+* Add - continuous RGB animations feature (between L and R halves) 
+* Fix - keymap files to adapt to changes
+    * all authors of keymaps confirmed this PR
+* Update - documents and rules.mk
+
+### Refactor of TKC1800 to use common OLED code
+
+[#8472](https://github.com/qmk/qmk_firmware/pull/8472)
+
+Modifies the default firmware for TKC1800 to use the in-built I2C and OLED drivers, instead of including and depending on its own set of libraries for the following functionality:
+
+- SSD1306 display
+- i2c for OLED
+
+This allows current TKC1800 firmware to advance with updates to those drivers, which are shared with other keyboards.
+
+#### To migrate existing TKC1800 firmware:
+
+[Changes to `config.h`](https://github.com/qmk/qmk_firmware/pull/8472/files#diff-d10b26e676b4a55cbb00d71955116526):
+- Remove `#define SSD1306OLED` from config.h
+
+[Changes to `tkc1800.c`](https://github.com/qmk/qmk_firmware/pull/8472/files#diff-3b35bd30abe89c8110717c6972cd2cc5):
+- Add the following to avoid debug errors on HID_listen if the screen is not present
+```c
+void keyboard_pre_init_kb(void) {
+  setPinInputHigh(D0);
+  setPinInputHigh(D1);
+
+  keyboard_pre_init_user();
+}
+```
+
+[Changes to `keymap.c`](https://github.com/qmk/qmk_firmware/pull/8472/files#diff-05a2a344ce27e4d045fe68520ccd4771):
+- Find/Replace each instance of `#ifdef SSD1306OLED` with `#ifdef OLED_DRIVER_ENABLE`
+- The following changes are for compatibility with the OLED driver. If you don't use the OLED driver you may safely delete [this section](https://github.com/qmk/qmk_firmware/blob/e6b9980bd45c186f7360df68c24b6e05a80c10dc/keyboards/lily58/keymaps/default/keymap.c#L144-L190)
+- [Remove](https://github.com/qmk/qmk_firmware/pull/6260/files#diff-20943ea59856e9bdf3d99ecb2eee40b7L91-L158) the block
+```c
+#ifdef SSD1306OLED	
+  iota_gfx_init(!has_usb());   // turns on the display	
+#endif
+```
+- Within the block bounded by `#ifdef OLED_DRIVER_ENABLE` and `#endif // OLED_DRIVER_ENABLE`, add the following block to ensure that your two OLEDs are rotated correctly across the left and right sides:
+```c
+oled_rotation_t oled_init_user(oled_rotation_t rotation) {
+  if (!is_keyboard_master())
+    return OLED_ROTATION_180;  // flips the display 180 degrees if offhand
+  return rotation;
+}
+```
+- Remove the function `iota_gfx_task_user`
+
+### Split HHKB to ANSI and JP layouts and Add VIA support for each
+
+[#8582](https://github.com/qmk/qmk_firmware/pull/8582)
+
+- Splits the HHKB codebase into two separate folders `keyboards/hhkb/ansi` and `keyboards/hhkb/jp`.
+- Adds VIA Configurator support for both versions.
+
+#### Migrating existing HHKB keymaps
+
+- Remove any checks for the `HHKB_JP` definition
+  - All checks for this definition have been removed, and each version uses the source that is appropriate to that version.
+- Move the directory for your keymap into the appropriate `keymaps` directory
+  - `keyboards/hhkb/ansi/keymaps/` for ANSI HHKBs
+  - `keyboards/hhkb/jp/keymaps/` for HHKB JPs
+- Compile with the new keyboard names
+  - This PR changes the compilation instructions for the HHKB Alternate Controller. To compile firmware for this controller moving forward, use:
+    - `make hhkb/ansi` for ANSI-layout HHKBs
+    - `make hhkb/jp` for HHKB JP keyboards

+# QMK Breaking Change - 2020 Aug 29 Changelog
+
+Four times a year QMK runs a process for merging Breaking Changes. A Breaking Change is any change which modifies how QMK behaves in a way that is incompatible or potentially dangerous. We limit these changes to 4 times per year so that users can have confidence that updating their QMK tree will not break their keymaps.
+
+
+## Changes Requiring User Action :id=changes-requiring-user-action
+
+### Relocated Keyboards :id-relocated-keyboards
+
+#### The Key Company project consolidation ([#9547](https://github.com/qmk/qmk_firmware/pull/9547))
+#### relocating boards by flehrad to flehrad/ folder ([#9635](https://github.com/qmk/qmk_firmware/pull/9635))
+
+Keyboards released by The Key Company and keyboards designed by flehrad have moved to vendor folders. If you own any of the keyboards listed below, please use the new names to compile your firmware moving forward.
+
+Old Name               | New Name

+
+### Updated Keyboard Codebases :id=keyboard-updates
+
+#### Keebio RGB wiring update ([#7754](https://github.com/qmk/qmk_firmware/pull/7754))
+
+This pull request changes the configuration for Keebio split boards to use the same RGB strip wiring for each half, which provides the following improvements:
+
+* Easier wiring due to one fewer wire needed (the wire between left DOut to extra data pin) and the fact that wiring is the same for both halves.
+* RGB LEDs can be controlled by each half now instead of just master half.
+* Extra data line is freed up to allow for I2C usage instead of serial.
+
+If you have customized the value of `RGBLED_SPLIT` for your keymap, you will need to undefine it using `#undef RGBLED_SPLIT` before defining it to your customized value.
+
+This change affects:
+
+* BFO-9000
+* Fourier
+* Iris rev2
+* Levinson, revs. 1 and 2
+* Nyquist, revs. 1 and 2
+* Quefrency rev1
+* Viterbi, revs. 1 and 2
+
+### Changes to Core Functionality :id=core-updates
+
+* Bigger Combo index ([#9318](https://github.com/qmk/qmk_firmware/pull/9318))
+
+Allows the Combo feature to support more than 256 combos.
+
+Any fork that uses `process_combo_event` needs to update the function's first argument to `uint16_t`:
+
+* Old function: `void process_combo_event(uint8_t combo_index, bool pressed)`
+* New function: `void process_combo_event(uint16_t combo_index, bool pressed)`
+
+
+## Core Changes :id=core-changes
+
+### Fixes :id=core-fixes
+
+* Mousekeys: scrolling acceleration is no longer coupled to mouse movement acceleration ([#9174](https://github.com/qmk/qmk_firmware/pull/9174))
+* Keymap Extras: correctly assign Question Mark in Czech layout ([#9987](https://github.com/qmk/qmk_firmware/pull/9987))
+
+### Additions and Enhancements :id=core-additions
+
+* allow for WS2812 PWM to work on DMAMUX-capable devices ([#9471](https://github.com/qmk/qmk_firmware/pull/9471))
+  * Newer STM32 MCUs have a DMAMUX peripheral, which allows mapping of DMAs to different DMA streams, rather than hard-defining the target streams in silicon.
+  * Affects STM32L4+ devices, as well as the soon-to-be-supported-by-QMK STM32G4/H7 families.
+  * Tested on F303/Proton C (ChibiOS v19, non-DMAMUX), G474 (ChibiOS v20, with DMAMUX).
+* dual-bank STM32 bootloader support ([#8778](https://github.com/qmk/qmk_firmware/pull/8778) and [#9738](https://github.com/qmk/qmk_firmware/pull/9738))
+  * Adds support for STM32 dual-bank flash bootloaders, by toggling a GPIO during early init in order to charge an RC circuit attached to `BOOT0`.
+  * The main rationale behind this is that dual-bank STM32 devices unconditionally execute user-mode code, regardless of whether or not the user-mode code jumps to the bootloader. If either flash bank is valid (and `BOOT0` is low), then the built-in bootloader will skip any sort of DFU.
+  * This PR allows for the initialisation sequencing to charge the RC circuit based on the example circuit posted on Discord, effectively pulling `BOOT0` high before issuing the system reset. As the RC circuit takes a while to discharge, the system reset executes the ROM bootloader which subsequently sees `BOOT0` high, and starts executing the DFU routines.
+  * Tested with STM32L082 (with current QMK+current ChibiOS), and STM32G474 (against ChibiOS 20.x).
+* update Space Cadet and Tap Dance features to use Custom Tapping Term when appropriate ([#6259](https://github.com/qmk/qmk_firmware/pull/6259))
+  * For the Tap Dance feature, this completely removes the need for the `ACTION_TAP_DANCE_FN_ADVANCED_TIME` dance.
+* HID Joystick Interface ([#4226](https://github.com/qmk/qmk_firmware/pull/4226) and [#9949](https://github.com/qmk/qmk_firmware/pull/9949 "Fix Joystick Compile Issues"))
+  * This implements a joystick feature, including a joystick_task function called from TMK, specific keycodes for joystick buttons and a USB HID interface.
+  * Tested on V-USB backend and Proton C; compiles but untested on LUFA.
+  * In order to test, you have to add `JOYSTICK_ENABLE = yes` to your `rules.mk` and
+    ```c
+    #define JOYSTICK_BUTTON_COUNT 8
+    #define JOYSTICK_AXES_COUNT 2
+    ```
+    in your config.h.
+* Christmas RGB Underglow animation now fades between green and red ([#7648](https://github.com/qmk/qmk_firmware/pull/7648))
+  * `RGBLIGHT_EFFECT_CHRISTMAS_INTERVAL` has been greatly decreased; please check your animation if you have customized this value.
+* layer state now initializes on startup ([#8318](https://github.com/qmk/qmk_firmware/pull/8318))
+  * This should produce more consistent behavior between the two functions and layer masks.
+* added support for HSV->RGB conversion without using CIE curve ([#9856](https://github.com/qmk/qmk_firmware/pull/9856))
+* added NOEEPROM functions for RGB Matrix ([#9487](https://github.com/qmk/qmk_firmware/pull/9487))
+  * Added eeprom_helpers for toggle, mode, sethsv, speed, similar to rgblight versions.
+  * Added set_speed function.
+  * Added helper functions, similar to those in rgblight, in order to add NOEEPROM versions of toggle, step, hue, sat, val, and speed.
+  * Minor: spelling correction for EEPROM in a debug message.
+* flashing firmware using `st-flash` utility from [STLink Tools](https://github.com/stlink-org/stlink) is now supported ([#9964](https://github.com/qmk/qmk_firmware/pull/9964))
+* add ability to dump all makefile variables for the specified target ([#8256](https://github.com/qmk/qmk_firmware/pull/8256))
+  * Adds a new subtarget to builds, `dump_vars`, which allows for printing out all the variables that make knows about, after all substitutions occur.
+  * Example: `make handwired/onekey/proton_c:default:dump_vars`
+* add ability to change the Auto Shift timeout in real time ([#8441](https://github.com/qmk/qmk_firmware/pull/8441))
+* added a timer implementation for backlight on ChibiOS ([#8291](https://github.com/qmk/qmk_firmware/pull/8291))
+* added a third endpoint to V-USB keyboards ([#9020](https://github.com/qmk/qmk_firmware/pull/9020))
+* added a method to read the OLED display buffer from user space ([#8777](https://github.com/qmk/qmk_firmware/pull/8777))
+* K-Type refactor ([#9864](https://github.com/qmk/qmk_firmware/pull/9864))
+  * The K-Type has been refactored to use QMK's native matrix scanning routine, and now has partial support for the RGB Matrix feature.
+* Joysticks can now be used without defining analog pins ([#10169](https://github.com/qmk/qmk_firmware/pull/10169))
+
+### Clean-ups and Optimizations :id=core-optimizations
+
+* iWRAP protocol removed ([#9284](https://github.com/qmk/qmk_firmware/pull/9284))
+* work begun for consolidation of ChibiOS platform files ([#8327](https://github.com/qmk/qmk_firmware/pull/8327) and [#9315](https://github.com/qmk/qmk_firmware/pull/9315))
+  * Start of the consolidation work to move the ChibiOS board definitions as well as the default set of configuration files for existing board definitions used by keyboards.
+    * Uses `/platforms/chibios` as previously discussed on discord.
+    * Consolidates the Proton C configs into the generic F303 definitions.
+    * Allows for defining a default set of `chconf.h`, `halconf.h`, and `mcuconf.h` files within the platform definition, which is able to be overridden by the keyboard directly, though include path ordering.
+    * Adds template `chconf.h`, `halconf.h`, `mcuconf.h`, and `board.h` that can be dropped into a keyboard directory, in order to override rather than replace the entire contents of the respective files.
+    * Removed Proton C QMK board definitions, falling back to ChibiOS board definitions with QMK overrides.
+* Various tidy-ups for USB descriptor code ([#9005](https://github.com/qmk/qmk_firmware/pull/9005))
+  * Renamed `keyboard_led_stats` in lufa.c and ChibiOS usb_main.c to `keyboard_led_state`, as well as `vusb_keyboard_leds`, for consistency
+  * Formatted CDC and MIDI descriptors better
+  * Removed `ENDPOINT_CONFIG` macro, it seems pointless and removes the need for endpoint address defines in the middle of the endpoint numbering enum
+  * Fixed (possibly?) V-USB `GET_REPORT` request handling. Not sure about this one, but the existing code appears to always return an empty report - now `send_keyboard` sets this variable to the current report, matching what the LUFA code does.
+* converted `CONSUMER2BLUEFRUIT()` and `CONSUMER2RN42()` macros to static inline functions ([#9055](https://github.com/qmk/qmk_firmware/pull/9055))
+* Additional cleanups for V-USB code ([#9310](https://github.com/qmk/qmk_firmware/pull/9310))
+  * Removing the UART stuff entirely, now that we have Console support. Also fixing up various other things; switching some `debug()` calls to `dprintf()`, moved `raw_hid_report` out of the way so that we can implement the shared endpoint stuff.
+* removed inclusion of `adafruit_ble.h` from `ssd1306.c` ([#9355](https://github.com/qmk/qmk_firmware/pull/9355))
+* `outputselect.c` is no longer compiled if Bluetooth is disabled ([#9356](https://github.com/qmk/qmk_firmware/pull/9356))
+* `analogRead()` deprecated in favor of `analogReadPin()` ([#9023](https://github.com/qmk/qmk_firmware/pull/9023))
+* forcibly disable NKRO on V-USB controllers ([#9054](https://github.com/qmk/qmk_firmware/pull/9054))
+* removed warning if running backlight on STM32F072 ([#10040](https://github.com/qmk/qmk_firmware/pull/10040))
+* removed unused CORTEX_VTOR_INIT rules.mk option ([#10053](https://github.com/qmk/qmk_firmware/pull/10053))
+* improved handling for enabling Link Time Optimization ([#9832](https://github.com/qmk/qmk_firmware/pull/9832))
+* streamline rules for supporting Kiibohd bootloader ([#10129](https://github.com/qmk/qmk_firmware/pull/10129))
+* Define `STM32_DMA_REQUIRED` when using DMA-based WS2812 driver on STM32 ([#10127](https://github.com/qmk/qmk_firmware/pull/10127))
+* fix DMA stream ID calculation in ws2812_pwm ([#10008](https://github.com/qmk/qmk_firmware/pull/10008))

 ## What is QMK Firmware?
 
-QMK (*Quantum Mechanical Keyboard*) is an open source community that maintains QMK Firmware, QMK Toolbox, qmk.fm, and these docs. QMK Firmware is a keyboard firmware based on the [tmk\_keyboard](http://github.com/tmk/tmk_keyboard) with some useful features for Atmel AVR controllers, and more specifically, the [OLKB product line](http://olkb.com), the [ErgoDox EZ](http://www.ergodox-ez.com) keyboard, and the [Clueboard product line](http://clueboard.co/). It has also been ported to ARM chips using ChibiOS. You can use it to power your own hand-wired or custom keyboard PCB.
+QMK (*Quantum Mechanical Keyboard*) is an open source community centered around developing computer input devices. The community encompasses all sorts of input devices, such as keyboards, mice, and MIDI devices. A core group of collaborators maintains [QMK Firmware](https://github.com/qmk/qmk_firmware), [QMK Configurator](https://config.qmk.fm), [QMK Toolbox](https://github.com/qmk/qmk_toolbox), [qmk.fm](https://qmk.fm), and this documentation with the help of community members like you.
 
-## How to Get It
+## Get Started
 
-If you plan on contributing a keymap, keyboard, or features to QMK, the easiest thing to do is [fork the repo through Github](https://github.com/qmk/qmk_firmware#fork-destination-box), and clone your repo locally to make your changes, push them, then open a [Pull Request](https://github.com/qmk/qmk_firmware/pulls) from your fork.
+Totally new to QMK? There are two ways to get started:
 
-Otherwise, you can clone it directly with `git clone https://github.com/qmk/qmk_firmware`. Do not download the zip or tar files; a git repository is required to download the submodules in order to compile.
+* Basic: [QMK Configurator](https://config.qmk.fm)
+    * Just select your keyboard from the dropdown and program your keyboard.
+    * We have an [introductory video](https://www.youtube.com/watch?v=-imgglzDMdY) you can watch.
+    * There is also an overview [document you can read](newbs_building_firmware_configurator.md).
+* Advanced: [Use The Source](newbs.md)
+    * More powerful, but harder to use
 
-## How to Compile
+## Make It Yours
 
-Before you are able to compile, you'll need to [install an environment](getting_started_build_tools.md) for AVR or/and ARM development. Once that is complete, you'll use the `make` command to build a keyboard and keymap with the following notation:
+QMK has lots of [features](features.md) to explore, and a good deal of reference documentation to dig through. Most features are taken advantage of by modifying your [keymap](keymap.md), and changing the [keycodes](keycodes.md).
 
-    make planck/rev4:default
+## Need help?
 
-This would build the `rev4` revision of the `planck` with the `default` keymap. Not all keyboards have revisions (also called subprojects or folders), in which case, it can be omitted:
+Check out the [support page](support.md) to see how you can get help using QMK.
 
-    make preonic:default
+## Give Back
 
-## How to Customize
+There are a lot of ways you can contribute to the QMK Community. The easiest way to get started is to use it and spread the word to your friends.

+## Configuration
+
+## ARM
+
+The ARM implementation of the ADC has a few additional options that you can override in your own keyboards and keymaps to change how it operates. Please consult the corresponding `hal_adc_lld.h` in ChibiOS for your specific microcontroller for further documentation on your available options.

+# QMK Compiler Development Guide
+
+This page attempts to introduce developers to the QMK Compiler. It does not go into nitty gritty details- for that you should read code. What this will give you is a framework to hang your understanding on as you read the code.
+
+# Overview
+
+The QMK Compile API consists of a few movings parts:
+
+![Architecture Diagram](https://raw.githubusercontent.com/qmk/qmk_api/master/docs/architecture.svg)
+
+API Clients interact exclusively with the API service. This is where they submit jobs, check status, and download results. The API service inserts compile jobs into [Redis Queue](https://python-rq.org) and checks both RQ and S3 for the results of those jobs.
+
+Workers fetch new compile jobs from RQ, compile them, and then upload the source and the binary to an S3 compatible storage engine.
+
+# Workers
+
+QMK Compiler Workers are responsible for doing the actual building. When a worker pulls a job from RQ it does several things to complete that job:
+
+* Make a fresh qmk_firmware checkout
+* Use the supplied layers and keyboard metadata to build a `keymap.c`
+* Build the firmware
+* Zip a copy of the source
+* Upload the firmware, source zip, and a metadata file to S3.
+* Report the status of the job to RQ
+
+# API Service
+
+The API service is a relatively simple Flask application. There are a few main views you should understand.
+
+## @app.route('/v1/compile', methods=['POST'])
+
+This is the main entrypoint for the API. A client's interaction starts here. The client POST's a JSON document describing their keyboard, and the API does some (very) basic validation of that JSON before submitting the compile job.
+
+## @app.route('/v1/compile/<string:job_id>', methods=['GET'])
+
+This is the most frequently called endpoint. It pulls the job details from redis, if they're still available, or the cached job details on S3 if they're not.
+
+## @app.route('/v1/compile/<string:job_id>/download', methods=['GET'])
+
+This method allows users to download the compiled firmware file.
+
+## @app.route('/v1/compile/<string:job_id>/source', methods=['GET'])
+
+This method allows users to download the source for their firmware.

+# QMK API
+
+This page describes using the QMK API. If you are an application developer you can use this API to compile firmware for any [QMK](https://qmk.fm) Keyboard.
+
+## Overview
+
+This service is an asynchronous API for compiling custom keymaps. You POST some JSON to the API, periodically check the status, and when your firmware has finished compiling you can download the resulting firmware and (if desired) source code for that firmware.
+
+#### Example JSON Payload:

+  ]
+}
+```
+
+As you can see the payload describes all aspects of a keyboard necessary to create and generate a firmware. Each layer is a single list of QMK keycodes the same length as the keyboard's `LAYOUT` macro. If a keyboard supports mulitple `LAYOUT` macros you can specify which macro to use.
+
+## Submitting a Compile Job
+
+To compile your keymap into a firmware simply POST your JSON to the `/v1/compile` endpoint. In the following example we've placed the JSON payload into a file named `json_data`.
+
+```
+$ curl -H "Content-Type: application/json" -X POST -d "$(< json_data)" http://api.qmk.fm/v1/compile
+{
+  "enqueued": true,
+  "job_id": "ea1514b3-bdfc-4a7b-9b5c-08752684f7f6"
+}
+```
+
+## Checking The Status
+
+After submitting your keymap you can check the status using a simple HTTP GET call:
+
+```
+$ curl http://api.qmk.fm/v1/compile/ea1514b3-bdfc-4a7b-9b5c-08752684f7f6
+{
+  "created_at": "Sat, 19 Aug 2017 21:39:12 GMT",
+  "enqueued_at": "Sat, 19 Aug 2017 21:39:12 GMT",
+  "id": "f5f9b992-73b4-479b-8236-df1deb37c163",
+  "status": "running",
+  "result": null
+}
+```
+
+This shows us that the job has made it through the queue and is currently running. There are 5 possible statuses:
+
+* **failed**: Something about the compiling service has broken.
+* **finished**: The compilation is complete and you should check `result` to see the results.
+* **queued**: The keymap is waiting for a compilation server to become available.
+* **running**: The compilation is in progress and should be complete soon.
+* **unknown**: A serious error has occurred and you should [file a bug](https://github.com/qmk/qmk_compiler/issues).
+
+## Examining Finished Results
+
+Once your compile job has finished you'll check the `result` key. The value of this key is a hash containing several key bits of information:
+
+* `firmware_binary_url`: A list of URLs for the the flashable firmware
+* `firmware_keymap_url`: A list of URLs for the the `keymap.c`
+* `firmware_source_url`: A list of URLs for the full firmware source code
+* `output`: The stdout and stderr for this compile job. Errors will be found here.

+# QMK API
+
+The QMK API provides an asynchronous API that Web and GUI tools can use to compile arbitrary keymaps for any keyboard supported by [QMK](http://qmk.fm/). The stock keymap template supports all QMK keycodes that do not require supporting C code. Keyboard maintainers can supply their own custom templates to enable more functionality.
+
+## App Developers
+
+If you are an app developer interested in using this API in your application you should head over to [Using The API](api_docs.md).
+
+## Keyboard Maintainers
+
+If you would like to enhance your keyboard's support in the QMK Compiler API head over to the [Keyboard Support](reference_configurator_support.md) section.
+
+## Backend Developers
+
+If you are interested in working on the API itself you should start by setting up a [Development Environment](api_development_environment.md), then check out [Hacking On The API](api_development_overview.md).

-# Becoming a QMK Collaborator
-
-A QMK collaborator is a keyboard maker or designer that is interested in helping QMK grow and fully support their keyboard(s), and encouraging their users and customers to submit features, ideas, and keymaps. We're always looking to add more keyboards and collaborators, but we ask that they fulfill these requirements:
-
-* **Have a PCB available for sale.** Unfortunately there's just too much variation and complications with handwired keyboards.
-* **Maintain your keyboard in QMK.** This may just require an initial setup to get your keyboard working, but it could also include accommodating changes made to QMK's core that might break or render any custom code redundant.
-* **Approve and merge keymap pull requests for your keyboard.** We like to encourage users to contribute their keymaps for others to see and work from when creating their own.
-
-If you feel you meet these requirements, shoot us an email at hello@qmk.fm with an introduction and some links to your keyboard!

-
-# Local CLI
-
-If you do not want to use the global CLI there is a local CLI bundled with `qmk_firmware`. You can find it in `qmk_firmware/bin/qmk`. You can run the `qmk` command from any directory and it will always operate on that copy of `qmk_firmware`.
-
-**Example**:
-
-```
-$ ~/qmk_firmware/bin/qmk hello
-Ψ Hello, World!
-```
-
-## Local CLI Limitations
-
-There are some limitations to the local CLI compared to the global CLI:
-
-* The local CLI does not support `qmk setup` or `qmk clone`
-* The local CLI always operates on the same `qmk_firmware` tree, even if you have multiple repositories cloned.
-* The local CLI does not run in a virtualenv, so it's possible that dependencies will conflict

 The QMK CLI operates using the subcommand pattern made famous by git. The main `qmk` script is simply there to setup the environment and pick the correct entrypoint to run. Each subcommand is a self-contained module with an entrypoint (decorated by `@cli.subcommand()`) that performs some action and returns a shell returncode, or None.
 
+## Developer mode:
+
+If you intend to maintain keyboards and/or contribute to QMK, you can enable the CLI's "Developer" mode:
+
+`qmk config user.developer=True`

+# QMK Configurator: Step by Step
+
+This page describes the steps for building your firmware in QMK Configurator.
+
+## Step 1: Select Your Keyboard
+
+Click the drop down box and select the keyboard you want to create a keymap for.
+
+?> If your keyboard has several versions, make sure you select the correct one.
+
+I'll say that again because it's important:
+
+!> **MAKE SURE YOU SELECT THE RIGHT VERSION!**
+
+If your keyboard has been advertised to be powered by QMK but is not in the list, chances are a developer hasn't gotten to it yet or we haven't had a chance to merge it in yet. File an issue at [qmk_firmware](https://github.com/qmk/qmk_firmware/issues) requesting to support that particular keyboard, if there is no active [Pull Request](https://github.com/qmk/qmk_firmware/pulls?q=is%3Aopen+is%3Apr+label%3Akeyboard) for it. There are also QMK powered keyboards that are in their manufacturer's own GitHub accounts. Double check for that as well.  <!-- FIXME(skullydazed): This feels too wordy and I'm not sure we want to encourage these kinds of issues. Also, should we prompt them to bug the manufacutrer? -->
+
+## Step 2: Select Your Keyboard Layout
+
+Choose the layout that best represents the keymap you want to create. Some keyboards do not have enough layouts or correct layouts defined yet. They will be supported in the future.
+
+!> Sometimes there isn't a layout that supports your exact build. In that case select `LAYOUT_all`.
+
+## Step 3: Name Your Keymap
+
+Call this keymap what you want.
+
+?> If you are running into issues when compiling, it may be worth changing this name, as it may already exist in the QMK Firmware repo.
+
+## Step 4: Define Your Keymap
+
+Keycode Entry is accomplished in one of 3 ways:
+
+1. Drag and drop
+2. Clicking on an empty spot on the layout, then clicking the keycode you desire
+3. Clicking on an empty spot on the layout, then pressing the physical key on your keyboard
+
+?> Hover your mouse over a key and a short blurb will tell you what that keycode does. For a more verbose description please see:
+
+* [Basic Keycode Reference](keycodes_basic.md)
+* [Advanced Keycode Reference](feature_advanced_keycodes.md)
+
+!> If your selected layout doesn't match your physical build leave the unused keys blank. If you're not sure which key is in use, for example you have a one backspace key but `LAYOUT_all` has 2 keys, put the same keycode in both locations.
+
+## Step 5: Save Your Keymap for Future Changes
+
+When you're satisfied with your keymap or just want to work on it later, press the `Export Keymap` button. It will save your keymap to your computer. You can then load this .json file in the future by pressing the `Import Keymap` button.
+
+!> **CAUTION:** This is not the same type of .json file used for kbfirmware.com or any other tool. If you try to use this for those tools, or the .json from those tools with QMK Configurator, you will encounter problems.
+
+## Step 6: Compile Your Firmware File
+
+Press the green `Compile` button.
+
+When the compilation is done, you will be able to press the green `Download Firmware` button.
+
+## Next steps: Flashing Your Keyboard
+
+Please refer to [Flashing Firmware](newbs_flashing.md).

+If not... how did you miss the big bold message at the top saying not to use other .json files?
+
+## There are extra spaces in my layout? What do I do?
+
+If you're referring to having three spots for space bar, the best course of action is to just fill them all with Space. The same can be done for Backspace and Shift keys.

These are called by QMK during key processing before the actual key event is handled. If these functions return `true` QMK will process the keycodes as usual. That can be handy for extending the functionality of a key rather than replacing it.

-# Custom Tapping Term
-
-By default, the tapping term and related options (such as `IGNORE_MOD_TAP_INTERRUPT`) are defined globally, and are not configurable by key.  For most users, this is perfectly fine.  But in some cases, dual function keys would be greatly improved by different timeout behaviors than `LT` keys, or because some keys may be easier to hold than others.  Instead of using custom key codes for each, this allows for per key configurable timeout behaviors.
-
-There are two configurable options to control per-key timeout behaviors:
-
-- `TAPPING_TERM_PER_KEY`
-- `IGNORE_MOD_TAP_INTERRUPT_PER_KEY`
-
-You need to add `#define` lines to your `config.h` for each feature you want.
-
-```
-#define TAPPING_TERM_PER_KEY
-#define IGNORE_MOD_TAP_INTERRUPT_PER_KEY
-```
-
-
-## Example `get_tapping_term` Implementation
-
-To change the `TAPPING_TERM` based on the keycode, you'd want to add something like the following to your `keymap.c` file:
-
-```c
-uint16_t get_tapping_term(uint16_t keycode) {
-  switch (keycode) {
-    case SFT_T(KC_SPC):
-      return TAPPING_TERM + 1250;
-    case LT(1, KC_GRV):
-      return 130;
-    default:
-      return TAPPING_TERM;
-  }
-}
-```
-
-## Example `get_ignore_mod_tap_interrupt` Implementation
-
-To change the `IGNORE_MOD_TAP_INTERRUPT` value based on the keycode, you'd want to add something like the following to your `keymap.c` file:
-
-```c
-bool get_ignore_mod_tap_interrupt(uint16_t keycode) {
-  switch (keycode) {
-    case SFT_T(KC_SPC):
-      return true;
-    default:
-      return false;
-  }
-}
-```
-
-## `get_tapping_term` / `get_ignore_mod_tap_interrupt` Function Documentation
-

-# Llegar a ser un colaborador QMK
-
-Un colaborador QMK es un maker o diseñador de teclados que tiene interés en ayudar a QMK a crecer y mantener sus teclado(s), y alentar a los usuarios y clientes a presentar herramientas, ideas, y keymaps. Siempre procuramos agregar más teclados y colaboradores, pero pedimos que cumplan los siguientes requisitos:
-
-* **Tener un PCB disponible a la venta.** Desafortunadamente, hay demasiada variación y complicaciones con teclados cableados a mano.
-* **Realizar el mantenimiento de tu teclado en QMK.** Este podría requirir un setup inicial para hacer que tu teclado funcione, pero también podría incluir adaptarse a cambios hecho al base de QMK que podrían descomponer o rendir código superfluo.
-* **Aprobar e incorporar pull requests de keymaps para tu teclado.** Nos gusta alentar a los usuarios a contribuir sus keymaps para que otros los vean y los puedan usar para crear sus propios.
-
-Si sientes que cumples los requisitos, ¡mándanos un email a hello@qmk.fm con una introducción y algunos enlaces para tu teclado!

 ## What Differences Are There Between QMK and TMK?
 
 TMK was originally designed and implemented by [Jun Wako](https://github.com/tmk). QMK started as [Jack Humbert](https://github.com/jackhumbert)'s fork of TMK for the Planck. After a while Jack's fork had diverged quite a bit from TMK, and in 2015 Jack decided to rename his fork to QMK.

+## How Can I Make Custom Names For Complex Keycodes?
+
+Sometimes, for readability's sake, it's useful to define custom names for some keycodes. People often define custom names using `#define`. For example:
+
+```c
+#define FN_CAPS LT(_FL, KC_CAPSLOCK)
+#define ALT_TAB LALT(KC_TAB)
+```
+
+This will allow you to use `FN_CAPS` and `ALT_TAB` in your keymap, keeping it more readable.
+
 ## Some Of My Keys Are Swapped Or Not Working
 
 QMK has two features, Bootmagic and Command, which allow you to change the behavior of your keyboard on the fly. This includes, but is not limited to, swapping Ctrl/Caps, disabling Gui, swapping Alt/Gui, swapping Backspace/Backslash, disabling all keys, and other behavioral modifications.

-# Advanced Keycodes
-
-Your keymap can include keycodes that are more advanced than normal, for example keys that switch layers or send modifiers when held, but send regular keycodes when tapped. This page documents the functions that are available to you.
-
-## Assigning Custom Names
-
-People often define custom names using `#define`. For example:
-

-
-## Caveats
-
-Currently, `LT()` and `MT()` are limited to the [Basic Keycode set](keycodes_basic.md), meaning you can't use keycodes like `LCTL()`, `KC_TILD`, or anything greater than `0xFF`. Modifiers specified as part of a Layer Tap or Mod Tap's keycode will be ignored. If you need to apply modifiers to your tapped keycode, [Tap Dance](feature_tap_dance.md#example-5-using-tap-dance-for-advanced-mod-tap-and-layer-tap-keys) can be used to accomplish this.
-
-Additionally, if at least one right-handed modifier is specified in a Mod Tap or Layer Tap, it will cause all modifiers specified to become right-handed, so it is not possible to mix and match the two.
-
-# Switching and Toggling Layers
-
-These functions allow you to activate layers in various ways. Note that layers are not generally independent layouts -- multiple layers can be activated at once, and it's typical for layers to use `KC_TRNS` to allow keypresses to pass through to lower layers. For a detailed explanation of layers, see [Keymap Overview](keymap.md#keymap-and-layers). When using momentary layer switching with MO(), LM(), TT(), or LT(), make sure to leave the key on the above layers transparent or it may not work as intended.
-
-* `DF(layer)` - switches the default layer. The default layer is the always-active base layer that other layers stack on top of. See below for more about the default layer. This might be used to switch from QWERTY to Dvorak layout. (Note that this is a temporary switch that only persists until the keyboard loses power. To modify the default layer in a persistent way requires deeper customization, such as calling the `set_single_persistent_default_layer` function inside of [process_record_user](custom_quantum_functions.md#programming-the-behavior-of-any-keycode).)
-* `MO(layer)` - momentarily activates *layer*. As soon as you let go of the key, the layer is deactivated. 
-* `LM(layer, mod)` - Momentarily activates *layer* (like `MO`), but with modifier(s) *mod* active. Only supports layers 0-15 and the left modifiers: `MOD_LCTL`, `MOD_LSFT`, `MOD_LALT`, `MOD_LGUI` (note the use of `MOD_` constants instead of `KC_`). These modifiers can be combined using bitwise OR, e.g. `LM(_RAISE, MOD_LCTL | MOD_LALT)`.
-* `LT(layer, kc)` - momentarily activates *layer* when held, and sends *kc* when tapped. Only supports layers 0-15.
-* `OSL(layer)` - momentarily activates *layer* until the next key is pressed. See [One Shot Keys](#one-shot-keys) for details and additional functionality.
-* `TG(layer)` - toggles *layer*, activating it if it's inactive and vice versa
-* `TO(layer)` - activates *layer* and de-activates all other layers (except your default layer). This function is special, because instead of just adding/removing one layer to your active layer stack, it will completely replace your current active layers, uniquely allowing you to replace higher layers with a lower one. This is activated on keydown (as soon as the key is pressed).
-* `TT(layer)` - Layer Tap-Toggle. If you hold the key down, *layer* is activated, and then is de-activated when you let go (like `MO`). If you repeatedly tap it, the layer will be toggled on or off (like `TG`). It needs 5 taps by default, but you can change this by defining `TAPPING_TOGGLE` -- for example, `#define TAPPING_TOGGLE 2` to toggle on just two taps.
-
-# Working with Layers
-
-Care must be taken when switching layers, it's possible to lock yourself into a layer with no way to deactivate that layer (without unplugging your keyboard.) We've created some guidelines to help users avoid the most common problems.
-
-## Beginners
-
-If you are just getting started with QMK you will want to keep everything simple. Follow these guidelines when setting up your layers:
-
-* Setup layer 0 as your default, "base" layer. This is your normal typing layer, and could be whatever layout you want (qwerty, dvorak, colemak, etc.). It's important to set this as the lowest layer since it will typically have most or all of the keyboard's keys defined, so would block other layers from having any effect if it were above them (i.e., had a higher layer number). 
-* Arrange your layers in a "tree" layout, with layer 0 as the root. Do not try to enter the same layer from more than one other layer.
-* In a layer's keymap, only reference higher-numbered layers. Because layers are processed from the highest-numbered (topmost) active layer down, modifying the state of lower layers can be tricky and error-prone.
-
-## Intermediate Users
-
-Sometimes you need more than one base layer. For example, if you want to switch between QWERTY and Dvorak, switch between layouts for different countries, or switch your layout for different videogames. Your base layers should always be the lowest numbered layers. When you have multiple base layers you should always treat them as mutually exclusive. When one base layer is on the others are off.
-
-## Advanced Users
-
-Once you have a good feel for how layers work and what you can do, you can get more creative. The rules listed in the beginner section will help you be successful by avoiding some of the tricker details but they can be constraining, especially for ultra-compact keyboard users. Understanding how layers work will allow you to use them in more advanced ways.
-
-Layers stack on top of each other in numerical order. When determining what a keypress does, QMK scans the layers from the top down, stopping when it reaches the first active layer that is not set to `KC_TRNS`. As a result if you activate a layer that is numerically lower than your current layer, and your current layer (or another layer that is active and higher than your target layer) has something other than `KC_TRNS`, that is the key that will be sent, not the key on the layer you just activated. This is the cause of most people's "why doesn't my layer get switched" problem.
-
-Sometimes, you might want to switch between layers in a macro or as part of a tap dance routine. `layer_on` activates a layer, and `layer_off` deactivates it. More layer-related functions can be found in [action_layer.h](https://github.com/qmk/qmk_firmware/blob/master/tmk_core/common/action_layer.h).

+## Tap-Hold Configuration Options :id=tap-hold-configuration-options
 
-## Caveats
-
-Unfortunately, these keycodes cannot be used in Mod-Taps or Layer-Taps, since any modifiers specified in the keycode are ignored.
-
-Additionally, you may run into issues when using Remote Desktop Connection on Windows. Because these codes send shift very fast, Remote Desktop may miss the codes.
-
-To fix this, open Remote Desktop Connection, click on "Show Options", open the the "Local Resources" tab. In the keyboard section, change the drop down to "On this Computer". This will fix the issue, and allow the characters to work correctly.
-
-# One Shot Keys
-
-One shot keys are keys that remain active until the next key is pressed, and then are released. This allows you to type keyboard combinations without pressing more than one key at a time. These keys are usually called "Sticky keys" or "Dead keys".
-
-For example, if you define a key as `OSM(MOD_LSFT)`, you can type a capital A character by first pressing and releasing shift, and then pressing and releasing A. Your computer will see the shift key being held the moment shift is pressed, and it will see the shift key being released immediately after A is released.
-
-One shot keys also work as normal modifiers. If you hold down a one shot key and type other keys, your one shot will be released immediately after you let go of the key.
-
-Additionally, hitting keys five times in a short period will lock that key. This applies for both One Shot Modifiers and One Shot Layers, and is controlled by the `ONESHOT_TAP_TOGGLE` define.
-
-You can control the behavior of one shot keys by defining these in `config.h`:
-
-```c
-#define ONESHOT_TAP_TOGGLE 5  /* Tapping this number of times holds the key until tapped once again. */
-#define ONESHOT_TIMEOUT 5000  /* Time (in ms) before the one shot key is released */
-```
-
-* `OSM(mod)` - Momentarily hold down *mod*. You must use the `MOD_*` keycodes as shown in [Mod Tap](#mod-tap), not the `KC_*` codes.
-* `OSL(layer)` - momentary switch to *layer*.
-
-Sometimes, you want to activate a one-shot key as part of a macro or tap dance routine.  
-
-For one shot layers, you need to call `set_oneshot_layer(LAYER, ONESHOT_START)` on key down, and `clear_oneshot_layer_state(ONESHOT_OTHER_KEY_PRESSED)` on key up. If you want to cancel the oneshot, call `reset_oneshot_layer()`.
-
-For one shot mods, you need to call `set_oneshot_mods(MOD)` to set it, or `clear_oneshot_mods()` to cancel it.
-
-!> If you're having issues with OSM translating over Remote Desktop Connection, this can be fixed by opening the settings, going to the "Local Resources" tap, and in the keyboard section, change the drop down to "On this Computer".  This will fix the issue and allow OSM to function properly over Remote Desktop.
-
-## Callbacks
-
-When you'd like to perform custom logic when pressing a one shot key, there are several callbacks you can choose to implement. You could indicate changes in one shot keys by flashing an LED or making a sound, for example.
-
-There is a callback for `OSM(mod)`. It is called whenever the state of any one shot modifier key is changed: when it toggles on, but also when it is toggled off. You can use it like this:
-
-```c
-void oneshot_mods_changed_user(uint8_t mods) {
-  if (mods & MOD_MASK_SHIFT) {
-    println("Oneshot mods SHIFT");
-  }
-  if (mods & MOD_MASK_CTRL) {
-    println("Oneshot mods CTRL");
-  }
-  if (mods & MOD_MASK_ALT) {
-    println("Oneshot mods ALT");
-  }
-  if (mods & MOD_MASK_GUI) {
-    println("Oneshot mods GUI");
-  }
-  if (!mods) {
-    println("Oneshot mods off");
-  }
-}
-```
-
-The `mods` argument contains the active mods after the change, so it reflects the current state.
-
-When you use One Shot Tap Toggle (by adding `#define ONESHOT_TAP_TOGGLE 2` in your `config.h` file), you may lock a modifier key by pressing it the specified amount of times. There's a callback for that, too:
-
-```c
-void oneshot_locked_mods_changed_user(uint8_t mods) {
-  if (mods & MOD_MASK_SHIFT) {
-    println("Oneshot locked mods SHIFT");
-  }
-  if (mods & MOD_MASK_CTRL) {
-    println("Oneshot locked mods CTRL");
-  }
-  if (mods & MOD_MASK_ALT) {
-    println("Oneshot locked mods ALT");
-  }
-  if (mods & MOD_MASK_GUI) {
-    println("Oneshot locked mods GUI");
-  }
-  if (!mods) {
-    println("Oneshot locked mods off");
-  }
-}
-```
-
-Last, there is also a callback for the `OSL(layer)` one shot key:
-
-```c
-void oneshot_layer_changed_user(uint8_t layer) {
-  if (layer == 1) {
-    println("Oneshot layer 1 on");
-  }
-  if (!layer) {
-    println("Oneshot layer off");
-  }
-}
-```
-
-If any one shot layer is switched off, `layer` will be zero. When you're looking to do something on any layer change instead of one shot layer changes, `layer_state_set_user` is a better callback to use.
-
-If you are making your own keyboard, there are also `_kb` equivalent functions:
-
-```c
-void oneshot_locked_mods_changed_kb(uint8_t mods);
-void oneshot_mods_changed_kb(uint8_t mods);
-void oneshot_layer_changed_kb(uint8_t layer);
-```
-
-As with any callback, be sure to call the `_user` variant to allow for further customizability.

-These options let you modify the behavior of the Tap-Hold keys.
-
-## Permissive Hold
-
-As of [PR#1359](https://github.com/qmk/qmk_firmware/pull/1359/), there is a new `config.h` option:
-
-```c
-#define PERMISSIVE_HOLD
-```
-
-This makes tap and hold keys (like Mod Tap) work better for fast typist, or for high `TAPPING_TERM` settings. 
-
-If you press a Mod Tap key, tap another key (press and release) and then release the Mod Tap key, all within the tapping term, it will output the "tapping" function for both keys.
-
-For Instance:
-
-- `SFT_T(KC_A)` Down
-- `KC_X` Down
-- `KC_X` Up
-- `SFT_T(KC_A)` Up
-
-Normally, if you do all this within the `TAPPING_TERM` (default: 200ms) this will be registered as `ax` by the firmware and host system. With permissive hold enabled, this modifies how this is handled by considering the Mod Tap keys as a Mod if another key is tapped, and would registered as `X` (`SHIFT`+`x`). 
-
-?> If you have `Ignore Mod Tap Interrupt` enabled, as well, this will modify how both work. The regular key has the modifier added if the first key is released first or if both keys are held longer than the `TAPPING_TERM`.
-
-## Ignore Mod Tap Interrupt
-
-To enable this setting, add this to your `config.h`:
-
-```c
-#define IGNORE_MOD_TAP_INTERRUPT
-```
-
-Similar to Permissive Hold, this alters how the firmware processes input for fast typist. If you press a Mod Tap key, press another key, release the Mod Tap key, and then release the normal key, it would normally output the "tapping" function for both keys. This may not be desirable for rolling combo keys. 
-
-Setting `Ignore Mod Tap Interrupt` requires  holding both keys for the `TAPPING_TERM` to trigger the hold function (the mod).
-
-For Instance:
-
-- `SFT_T(KC_A)` Down
-- `KC_X` Down
-- `SFT_T(KC_A)` Up
-- `KC_X` Up
-
-Normally, this would send `X` (`SHIFT`+`x`). With `Ignore Mod Tap Interrupt` enabled, holding both keys are required for the `TAPPING_TERM` to register the hold action. A quick tap will output `ax` in this case, while a hold on both will still output `X`  (`SHIFT`+`x`).
-
-
-?> __Note__: This only concerns modifiers and not layer switching keys.
-
-?> If you have `Permissive Hold` enabled, as well, this will modify how both work. The regular key has the modifier added if the first key is released first or if both keys are held longer than the `TAPPING_TERM`.
-
-For more granular control of this feature, you can add the following to your `config.h`:
-
-```c
-#define IGNORE_MOD_TAP_INTERRUPT_PER_KEY
-```
-
-You can then add the following function to your keymap:
-
-```c
-bool get_ignore_mod_tap_interrupt(uint16_t keycode) {
-  switch (keycode) {
-    case SFT_T(KC_SPC):
-      return true;
-    default:
-      return false;
-  }
-}
-```
-
-## Tapping Force Hold
-
-To enable `tapping force hold`, add the following to your `config.h`: 
-
-```c
-#define TAPPING_FORCE_HOLD
-```
-
-When the user holds a key after tap, this repeats the tapped key rather to hold a modifier key.  This allows to use auto repeat for the tapped key.  
-
-Example:
-
-- SFT_T(KC_A) Down
-- SFT_T(KC_A) Up
-- SFT_T(KC_A) Down
-- wait more than tapping term...
-- SFT_T(KC_A) Up
-
-With default settings, `a` will be sent on the first release, then `a` will be sent on the second press allowing the computer to trigger its auto repeat function.
-
-With `TAPPING_FORCE_HOLD`, the second press will be interpreted as a Shift, allowing to use it as a modifier shortly after having used it as a tap.
-
-!> `TAPPING_FORCE_HOLD` will break anything that uses tapping toggles (Such as the `TT` layer keycode, and the One Shot Tapping Toggle).
-
-For more granular control of this feature, you can add the following to your `config.h`:
-
-```c
-#define TAPPING_FORCE_HOLD_PER_KEY
-```
-
-You can then add the following function to your keymap:
-
-```c
-bool get_tapping_force_hold(uint16_t keycode, keyrecord_t *record) {
-  switch (keycode) {
-    case LT(1, KC_BSPC):
-      return true;
-    default:
-      return false;
-  }
-}
-```
-
-## Retro Tapping
-
-To enable `retro tapping`, add the following to your `config.h`: 
-
-```c
-#define RETRO_TAPPING
-```
-
-Holding and releasing a dual function key without pressing another key will result in nothing happening. With retro tapping enabled, releasing the key without pressing another will send the original keycode even if it is outside the tapping term.
-
-For instance, holding and releasing `LT(2, KC_SPACE)` without hitting another key will result in nothing happening. With this enabled, it will send `KC_SPACE` instead.

 Many keyboards support backlit keys by way of individual LEDs placed through or underneath the keyswitches. This feature is distinct from both the [RGB underglow](feature_rgblight.md) and [RGB matrix](feature_rgb_matrix.md) features as it usually allows for only a single colour per switch, though you can obviously install multiple different single coloured LEDs on a keyboard.

+### Backlight On State :id=backlight-on-state
 
 Most backlight circuits are driven by an N-channel MOSFET or NPN transistor. This means that to turn the transistor *on* and light the LEDs, you must drive the backlight pin, connected to the gate or base, *high*.
 Sometimes, however, a P-channel MOSFET, or a PNP transistor is used. In this case, when the transistor is on, the pin is driven *low* instead.
 
 This functionality is configured at the keyboard level with the `BACKLIGHT_ON_STATE` define.

-### Multiple backlight pins
-
-Most keyboards have only one backlight pin which control all backlight LEDs (especially if the backlight is connected to an hardware PWM pin).
-In software PWM, it is possible to define multiple backlight pins. All those pins will be turned on and off at the same time during the PWM duty cycle.
-This feature allows to set for instance the Caps Lock LED (or any other controllable LED) brightness at the same level as the other LEDs of the backlight. This is useful if you have mapped LCTRL in place of Caps Lock and you need the Caps Lock LED to be part of the backlight instead of being activated when Caps Lock is on.
-
-To activate multiple backlight pins, you need to add something like this to your user `config.h`:
-
-```c
-#define BACKLIGHT_LED_COUNT 2
-#undef BACKLIGHT_PIN
-#define BACKLIGHT_PINS { F5, B2 }
-```
-
-### Hardware PWM Implementation
+#### Hardware PWM Implementation :id=hardware-pwm-implementation
 
 When using the supported pins for backlighting, QMK will use a hardware timer configured to output a PWM signal. This timer will count up to `ICRx` (by default `0xFFFF`) before resetting to 0.
 The desired brightness is calculated and stored in the `OCRxx` register. When the counter reaches this value, the backlight pin will go low, and is pulled high again when the counter resets.
@@ -147,7 +127,7 @@ In this way `OCRxx` essentially controls the duty cycle of the LEDs, and thus th
 The breathing effect is achieved by registering an interrupt handler for `TIMER1_OVF_vect` that is called whenever the counter resets, roughly 244 times per second.
 In this handler, the value of an incrementing counter is mapped onto a precomputed brightness curve. To turn off breathing, the interrupt handler is simply disabled, and the brightness reset to the level stored in EEPROM.
 
-### Timer Assisted PWM Implementation

-### Multiple backlight pins
+#### Multiple Backlight Pins :id=multiple-backlight-pins
 
 Most keyboards have only one backlight pin which control all backlight LEDs (especially if the backlight is connected to an hardware PWM pin).
-In software PWM, it is possible to define multiple backlight pins. All those pins will be turned on and off at the same time during the PWM duty cycle.
-This feature allows to set for instance the Caps Lock LED (or any other controllable LED) brightness at the same level as the other LEDs of the backlight. This is useful if you have mapped LCTRL in place of Caps Lock and you need the Caps Lock LED to be part of the backlight instead of being activated when Caps Lock is on.
+In software PWM, it is possible to define multiple backlight pins, which will be turned on and off at the same time during the PWM duty cycle.

+    // Optional - runs periodically
+    //   Note that this is called in the main keyboard loop,
+    //   so long running actions here can cause performance issues
 }
 ```
+
+## Example Schematic
+
+In this typical example, the backlight LEDs are all connected in parallel towards an N-channel MOSFET. Its gate pin is wired to one of the microcontroller's GPIO pins through a 470Ω resistor to avoid ringing.
+A pulldown resistor is also placed between the gate pin and ground to keep it at a defined state when it is not otherwise being driven by the MCU.
+The values of these resistors are not critical - see [this Electronics StackExchange question](https://electronics.stackexchange.com/q/68748) for more information.

+## Joystick
+
+The keyboard can be made to be recognized as a joystick HID device by the operating system.
+
+This is enabled by adding `JOYSTICK_ENABLE` to `rules.mk`. You can set this value to `analog`, `digital`, or `no`.
+
+!> Joystick support is not currently available on V-USB devices.
+
+The joystick feature provides two services:
+ * reading analog input devices (eg. potentiometers)
+ * sending gamepad HID reports
+
+Both services can be used without the other, depending on whether you just want to read a device but not send gamepad reports (for volume control for instance)
+or send gamepad reports based on values computed by the keyboard.
+
+### Analog Input
+
+To use analog input you must first enable it in `rules.mk`:
+
+```makefile
+JOYSTICK_ENABLE = analog
+```
+
+An analog device such as a potentiometer found on a gamepad's analog axes is based on a [voltage divider](https://en.wikipedia.org/wiki/Voltage_divider).
+It is composed of three connectors linked to the ground, the power input and power output (usually the middle one). The power output holds the voltage that varies based on the position of the cursor,
+which value will be read using your MCU's [ADC](https://en.wikipedia.org/wiki/Analog-to-digital_converter).
+Depending on which pins are already used by your keyboard's matrix, the rest of the circuit can get a little bit more complicated,
+feeding the power input and ground connection through pins and using diodes to avoid bad interactions with the matrix scanning procedures.
+
+### Configuring the Joystick
+
+By default, two axes and eight buttons are defined. This can be changed in your `config.h`:
+
+```c
+// Max 32
+#define JOYSTICK_BUTTON_COUNT 16
+// Max 6: X, Y, Z, Rx, Ry, Rz
+#define JOYSTICK_AXES_COUNT 3
+```
+
+When defining axes for your joystick, you have to provide a definition array. You can do this from your keymap.c file.
+A joystick will either be read from an input pin that allows the use of the ADC, or can be virtual, so that its value is provided by your code.
+You have to define an array of type ''joystick_config_t'' and of proper size.
+
+There are three ways for your circuit to work with the ADC, that relies on the use of 1, 2 or 3 pins of the MCU:
+ * 1 pin: your analog device is directly connected to your device GND and VCC. The only pin used is the ADC pin of your choice.
+ * 2 pins: your analog device is powered through a pin that allows toggling it on or off. The other pin is used to read the input value through the ADC.
+ * 3 pins: both the power input and ground are connected to pins that must be set to a proper state before reading and restored afterwards.
+
+The configuration of each axis is performed using one of four macros:
+ * `JOYSTICK_AXIS_VIRTUAL`: no ADC reading must be performed, that value will be provided by keyboard/keymap-level code
+ * `JOYSTICK_AXIS_IN(INPUT_PIN, LOW, REST, HIGH)`: a voltage will be read on the provided pin, which must be an ADC-capable pin.
+ * `JOYSTICK_AXIS_IN_OUT(INPUT_PIN, OUTPUT_PIN, LOW, REST, HIGH)`: the provided `OUTPUT_PIN` will be set high before `INPUT_PIN` is read.
+ * `JOYSTICK_AXIS_IN_OUT_GROUND(INPUT_PIN, OUTPUT_PIN, GROUND_PIN, LOW, REST, HIGH)`: the `OUTPUT_PIN` will be set high and `GROUND_PIN` will be set low before reading from `INPUT_PIN`.
+
+In any case where an ADC reading takes place (when `INPUT_PIN` is provided), additional `LOW`, `REST` and `HIGH` parameters are used.
+These implement the calibration of the analog device by defining the range of read values that will be mapped to the lowest, resting position and highest possible value for the axis (-127 to 127).
+In practice, you have to provide the lowest/highest raw ADC reading, and the raw reading at resting position, when no deflection is applied. You can provide inverted `LOW` and `HIGH` to invert the axis.
+
+For instance, an axes configuration can be defined in the following way:
+
+```c
+//joystick config
+joystick_config_t joystick_axes[JOYSTICK_AXES_COUNT] = {
+    [0] = JOYSTICK_AXIS_IN_OUT_GROUND(A4, B0, A7, 900, 575, 285),
+    [1] = JOYSTICK_AXIS_VIRTUAL
+};
+```
+
+When the ADC reads 900 or higher, the returned axis value will be -127, whereas it will be 127 when the ADC reads 285 or lower. Zero is returned when 575 is read.
+
+In this example, the first axis will be read from the `A4` pin while `B0` is set high and `A7` is set low, using `analogReadPin()`, whereas the second axis will not be read.
+
+In order to give a value to the second axis, you can do so in any customizable entry point: as an action, in `process_record_user()` or in `matrix_scan_user()`, or even in `joystick_task()` which is called even when no key has been pressed.
+You assign a value by writing to `joystick_status.axes[axis_index]` a signed 8-bit value (ranging from -127 to 127). Then it is necessary to assign the flag `JS_UPDATED` to `joystick_status.status` in order for an updated HID report to be sent.
+
+The following example writes two axes based on keypad presses, with `KC_P5` as a precision modifier:
+

+# Layers :id=layers
+
+One of the most powerful and well used features of QMK Firmware is the ability to use layers.  For most people, this amounts to a function key that allows for different keys, much like what you would see on a laptop or tablet keyboard. 
+
+For a detailed explanation of how the layer stack works, checkout [Keymap Overview](keymap.md#keymap-and-layers).
+
+## Switching and Toggling Layers :id=switching-and-toggling-layers
+
+These functions allow you to activate layers in various ways. Note that layers are not generally independent layouts -- multiple layers can be activated at once, and it's typical for layers to use `KC_TRNS` to allow keypresses to pass through to lower layers. When using momentary layer switching with MO(), LM(), TT(), or LT(), make sure to leave the key on the above layers transparent or it may not work as intended.
+
+* `DF(layer)` - switches the default layer. The default layer is the always-active base layer that other layers stack on top of. See below for more about the default layer. This might be used to switch from QWERTY to Dvorak layout. (Note that this is a temporary switch that only persists until the keyboard loses power. To modify the default layer in a persistent way requires deeper customization, such as calling the `set_single_persistent_default_layer` function inside of [process_record_user](custom_quantum_functions.md#programming-the-behavior-of-any-keycode).)
+* `MO(layer)` - momentarily activates *layer*. As soon as you let go of the key, the layer is deactivated. 
+* `LM(layer, mod)` - Momentarily activates *layer* (like `MO`), but with modifier(s) *mod* active. Only supports layers 0-15 and the left modifiers: `MOD_LCTL`, `MOD_LSFT`, `MOD_LALT`, `MOD_LGUI` (note the use of `MOD_` constants instead of `KC_`). These modifiers can be combined using bitwise OR, e.g. `LM(_RAISE, MOD_LCTL | MOD_LALT)`.
+* `LT(layer, kc)` - momentarily activates *layer* when held, and sends *kc* when tapped. Only supports layers 0-15.
+* `OSL(layer)` - momentarily activates *layer* until the next key is pressed. See [One Shot Keys](one_shot_keys.md) for details and additional functionality.
+* `TG(layer)` - toggles *layer*, activating it if it's inactive and vice versa
+* `TO(layer)` - activates *layer* and de-activates all other layers (except your default layer). This function is special, because instead of just adding/removing one layer to your active layer stack, it will completely replace your current active layers, uniquely allowing you to replace higher layers with a lower one. This is activated on keydown (as soon as the key is pressed).
+* `TT(layer)` - Layer Tap-Toggle. If you hold the key down, *layer* is activated, and then is de-activated when you let go (like `MO`). If you repeatedly tap it, the layer will be toggled on or off (like `TG`). It needs 5 taps by default, but you can change this by defining `TAPPING_TOGGLE` -- for example, `#define TAPPING_TOGGLE 2` to toggle on just two taps.
+
+### Caveats :id=caveats
+
+Currently, `LT()` and `MT()` are limited to the [Basic Keycode set](keycodes_basic.md), meaning you can't use keycodes like `LCTL()`, `KC_TILD`, or anything greater than `0xFF`. Specifically, dual function keys like `LT` and `MT` use a 16 bit keycode. 4 bits are used for the function identifier, the next 12 are divided into the parameters. Layer Tap uses 4 bits for the layer (and is why it's limited to layers 0-15, actually), while Mod Tap does the same, 4 bits for the identifier, 4 bits for which mods are used, and all of them use 8 bits for the keycode. Because of this, the keycode used is limited to `0xFF` (0-255), which are the basic keycodes only. 
+
+Expanding this would be complicated, at best. Moving to a 32-bit keycode would solve a lot of this, but would double the amount of space that the keymap matrix uses. And it could potentially cause issues, too. If you need to apply modifiers to your tapped keycode, [Tap Dance](feature_tap_dance.md#example-5-using-tap-dance-for-advanced-mod-tap-and-layer-tap-keys) can be used to accomplish this.
+
+Additionally, if at least one right-handed modifier is specified in a Mod Tap or Layer Tap, it will cause all modifiers specified to become right-handed, so it is not possible to mix and match the two.
+
+## Working with Layers :id=working-with-layers
+
+Care must be taken when switching layers, it's possible to lock yourself into a layer with no way to deactivate that layer (without unplugging your keyboard.) We've created some guidelines to help users avoid the most common problems.
+
+### Beginners :id=beginners
+
+If you are just getting started with QMK you will want to keep everything simple. Follow these guidelines when setting up your layers:
+
+* Setup layer 0 as your default, "base" layer. This is your normal typing layer, and could be whatever layout you want (qwerty, dvorak, colemak, etc.). It's important to set this as the lowest layer since it will typically have most or all of the keyboard's keys defined, so would block other layers from having any effect if it were above them (i.e., had a higher layer number). 
+* Arrange your layers in a "tree" layout, with layer 0 as the root. Do not try to enter the same layer from more than one other layer.
+* In a layer's keymap, only reference higher-numbered layers. Because layers are processed from the highest-numbered (topmost) active layer down, modifying the state of lower layers can be tricky and error-prone.
+
+### Intermediate Users :id=intermediate-users
+
+Sometimes you need more than one base layer. For example, if you want to switch between QWERTY and Dvorak, switch between layouts for different countries, or switch your layout for different videogames. Your base layers should always be the lowest numbered layers. When you have multiple base layers you should always treat them as mutually exclusive. When one base layer is on the others are off.
+
+### Advanced Users :id=advanced-users
+
+Once you have a good feel for how layers work and what you can do, you can get more creative. The rules listed in the beginner section will help you be successful by avoiding some of the tricker details but they can be constraining, especially for ultra-compact keyboard users. Understanding how layers work will allow you to use them in more advanced ways.
+
+Layers stack on top of each other in numerical order. When determining what a keypress does, QMK scans the layers from the top down, stopping when it reaches the first active layer that is not set to `KC_TRNS`. As a result if you activate a layer that is numerically lower than your current layer, and your current layer (or another layer that is active and higher than your target layer) has something other than `KC_TRNS`, that is the key that will be sent, not the key on the layer you just activated. This is the cause of most people's "why doesn't my layer get switched" problem.
+
+Sometimes, you might want to switch between layers in a macro or as part of a tap dance routine. `layer_on` activates a layer, and `layer_off` deactivates it. More layer-related functions can be found in [action_layer.h](https://github.com/qmk/qmk_firmware/blob/master/tmk_core/common/action_layer.h).
+
+## Functions :id=functions
+
+There are a number of functions (and variables) related to how you can use or manipulate the layers.

+# Raw HID
+
+Raw HID allows for bidirectional communication between QMK and the host computer over an HID interface. This has many potential use cases, such as switching keymaps on the fly or changing RGB LED colors and modes.
+
+There are two main components to getting raw HID working with your keyboard.
+
+## Keyboard firmware
+
+The implementation is fairly straightforward for the firmware.
+In your `rules.mk` add:
+
+```make
+RAW_ENABLE = yes
+```
+
+In your `keymap.c` include `"raw_hid.h"` and implement the following:
+
+```C
+void raw_hid_receive(uint8_t *data, uint8_t length) {
+    // Your code goes here. data is the packet received from host.
+}
+```
+
+The `"raw_hid.h"` header also declares `void raw_hid_send(uint8_t *data, uint8_t length);` which allows sending packets from keyboard to host. As an example, it can also be used for debugging when building your host application by returning all data back to the host.
+
+```C
+void raw_hid_receive(uint8_t *data, uint8_t length) {
+    raw_hid_send(data, length);
+}
+```
+
+`raw_hid_receive` can receive variable size packets from host with maximum length `RAW_EPSIZE`. `raw_hid_send` on the other hand can send packets to host of exactly `RAW_EPSIZE` length, therefore it should be used with data of length `RAW_EPSIZE`.
+
+Make sure to flash raw enabled firmware before proceeding with working on the host side.
+
+## Host (Windows/macOS/Linux)
+
+This is the more complicated part as it will require some digging.
+
+To connect your host computer to your keyboard with raw HID you need four pieces of information about your keyboard:
+
+1. Vendor ID
+2. Product ID
+3. Usage Page
+4. Usage
+
+The first two can easily be found in your keyboard's `config.h` in the keyboard's main directory under `VENDOR_ID` and `PRODUCT_ID`.
+
+The final two can be overridden in your keyboard's `config.h` in the keyboard's main directory by redefining the values: `#define RAW_USAGE_PAGE 0xFF60` and `#define RAW_USAGE_ID 0x61`.
+
+By default, **Usage Page** is `0xFF60` and **Usage** is `0x61`.
+
+### Building your host
+
+You can build your host using any language that has an available HID implementation library if you don't wish to make your own. The ones we know of for popular languages are:
+
+* Node: [node-hid](https://github.com/node-hid/node-hid).
+* C: [hidapi](https://github.com/libusb/hidapi).
+* Java: [purejavahidapi](https://github.com/nyholku/purejavahidapi) and [hid4java](https://github.com/gary-rowe/hid4java).
+* Python: [pyhidapi](https://pypi.org/project/hid/).
+
+This is not an exhaustive cross-platform list but should get you started. There are no special requirements for using raw HID so any HID library should work.
+
+Now that you have all four pieces of information required to open HID interface to your keyboard. All you need to do is use your library's available functions to open the device with its ID parameters.
+
+Note that Vendor ID and Product ID are not actually required to open the device. They are used only to filter to a specific device out of the many HID devices you have plugged in. Many libraries will give you the option to open the device using Product Name or Manufacturer Name instead, `node-hid` being a prime example. This will create issues for devices with builtin USB Hub or any extra HID interfaces where you will have multiple interfaces with the same name or from the same manufacturer. The Vendor ID together with Product ID create a unique designation to a single interface and will not exhibit this problem. Therefore, even if your library doesn't require you to, it is best to use them to avoid issues.
+Unlike Vendor ID and Product ID though, Usage Page and Usage are necessary for successful communication.
+
+It should go without saying that regardless of the library you're using, you should always make sure to close the interface when finished. Depending on the operating system and your particular environment there may be issues connecting to it again afterwards with another client or another instance of the same client if it's not explicitly closed.

+If you want to set custom indicators, such as an LED for Caps Lock, or layer indication, you can use the `rgb_matrix_indicators_kb` or `rgb_matrix_indicators_user` function for that: 
+```c
+void rgb_matrix_indicators_kb(void) {
+    rgb_matrix_set_color(index, red, green, blue);
+}
+```
+
+### Suspended state :id=suspended-state
+To use the suspend feature, make sure that `#define RGB_DISABLE_WHEN_USB_SUSPENDED true` is added to the `config.h` file. 
+
+Additionally add this to your `<keyboard>.c`:
+
+```c
+void suspend_power_down_kb(void) {
+    rgb_matrix_set_suspend_state(true);
+    suspend_power_down_user();
+}
+
+void suspend_wakeup_init_kb(void) {
+    rgb_matrix_set_suspend_state(false);
+    suspend_wakeup_init_user();
+}
+```
+or add this to your `keymap.c`:
+```c
+void suspend_power_down_user(void) {
     rgb_matrix_set_suspend_state(true);
 }
 
-void suspend_wakeup_init_kb(void)
-{
+void suspend_wakeup_init_user(void) {
     rgb_matrix_set_suspend_state(false);
 }

+## Lighting Layers
+
+By including `#define RGBLIGHT_LAYERS` in your `config.h` file you can enable lighting layers. These make
+it easy to use your underglow LEDs as status indicators to show which keyboard layer is currently active, or the state of caps lock, all without disrupting any animations. [Here's a video](https://youtu.be/uLGE1epbmdY) showing an example of what you can do.
+
+### Defining Lighting Layers :id=defining-lighting-layers
+
+By default, 8 layers are possible. This can be expanded to as many as 32 by overriding the definition of `RGBLIGHT_MAX_LAYERS` in `config.h` (e.g. `#define RGBLIGHT_MAX_LAYERS 32`). Please note, if you use a split keyboard, you will need to flash both sides of the split after changing this. Also, increasing the maximum will increase the firmware size, and will slow sync on split keyboards.
+
+To define a layer, we modify `keymap.c` to list out LED ranges and the colors we want to overlay on them using an array of `rgblight_segment_t` using the `RGBLIGHT_LAYER_SEGMENTS` macro. We can define multiple layers and enable/disable them independently:
+
+```c
+// Light LEDs 6 to 9 and 12 to 15 red when caps lock is active. Hard to ignore!
+const rgblight_segment_t PROGMEM my_capslock_layer[] = RGBLIGHT_LAYER_SEGMENTS(
+    {6, 4, HSV_RED},       // Light 4 LEDs, starting with LED 6
+    {12, 4, HSV_RED}       // Light 4 LEDs, starting with LED 12
+);
+// Light LEDs 9 & 10 in cyan when keyboard layer 1 is active
+const rgblight_segment_t PROGMEM my_layer1_layer[] = RGBLIGHT_LAYER_SEGMENTS(
+    {9, 2, HSV_CYAN}
+);
+// Light LEDs 11 & 12 in purple when keyboard layer 2 is active
+const rgblight_segment_t PROGMEM my_layer2_layer[] = RGBLIGHT_LAYER_SEGMENTS(
+    {11, 2, HSV_PURPLE}
+);
+// etc..
+```
+
+We combine these layers into an array using the `RGBLIGHT_LAYERS_LIST` macro, and assign it to the `rgblight_layers` variable during keyboard setup. Note that you can only define up to 8 lighting layers. Any extra layers will be ignored. Since the different lighting layers overlap, the order matters in the array, with later layers taking precedence:
+
+```c
+// Now define the array of layers. Later layers take precedence
+const rgblight_segment_t* const PROGMEM my_rgb_layers[] = RGBLIGHT_LAYERS_LIST(
+    my_capslock_layer,
+    my_layer1_layer,    // Overrides caps lock layer
+    my_layer2_layer     // Overrides other layers
+);
+
+void keyboard_post_init_user(void) {
+    // Enable the LED layers
+    rgblight_layers = my_rgb_layers;
+}
+```
+Note: For split keyboards with two controllers, both sides need to be flashed when updating the contents of rgblight_layers.
+
+### Enabling and disabling lighting layers :id=enabling-lighting-layers
+
+Everything above just configured the definition of each lighting layer.
+We can now enable and disable the lighting layers whenever the state of the keyboard changes:
+
+```c
+layer_state_t layer_state_set_user(layer_state_t state) {
+    // Both layers will light up if both kb layers are active
+    rgblight_set_layer_state(1, layer_state_cmp(state, 1));
+    rgblight_set_layer_state(2, layer_state_cmp(state, 2));
+    return state;
+}
+
+bool led_update_user(led_t led_state) {
+    rgblight_set_layer_state(0, led_state.caps_lock);
+    return true;
+}
+```
+
+### Lighting layer blink :id=lighting-layer-blink
+
+By including `#define RGBLIGHT_LAYER_BLINK` in your `config.h` file you can turn a lighting
+layer on for a specified duration. Once the specified number of milliseconds has elapsed
+the layer will be turned off. This is useful, e.g., if you want to acknowledge some
+action (e.g. toggling some setting):
+
+```c
+const rgblight_segment_t PROGMEM _yes_layer[] = RGBLIGHT_LAYER_SEGMENTS( {9, 6, HSV_GREEN} );
+const rgblight_segment_t PROGMEM _no_layer[] = RGBLIGHT_LAYER_SEGMENTS( {9, 6, HSV_RED} );
+
+const rgblight_segment_t* const PROGMEM _rgb_layers[] =
+    RGBLIGHT_LAYERS_LIST( _yes_layer, _no_layer );
+
+void keyboard_post_init_user(void) {
+    rgblight_layers = _rgb_layers;
+}
+
+// Note we user post_process_record_user because we want the state
+// after the flag has been flipped...
+void post_process_record_user(uint16_t keycode, keyrecord_t *record) {
+    switch (keycode) {
+        case DEBUG:
+            rgblight_blink_layer(debug_enable ? 0 : 1, 500);
+            break;
+
+        case NK_TOGG:
+        case NK_ON:
+        case NK_OFF:
+            rgblight_blink_layer(keymap_config.nkro ? 0 : 1, 500);
+            break;
+    }
+}
+```
+
+### Overriding RGB Lighting on/off status
+
+Normally lighting layers are not shown when RGB Lighting is disabled (e.g. with `RGB_TOG` keycode). If you would like lighting layers to work even when the RGB Lighting is otherwise off, add `#define RGBLIGHT_LAYERS_OVERRIDE_RGB_OFF` to your `config.h`.

+#### Handedness by Matrix Pin
+
+You can configure the firmware to read key matrix pins on the controller to determine handedness.  To do this, add the following to your `config.h` file:
+
+```c
+#define SPLIT_HAND_MATRIX_GRID D0, F1
+```
+
+The first pin is the output pin and the second is the input pin.
+
+Some keyboards have unused intersections in the key matrix. This setting uses one of these unused intersections to determine the handness.

 #### Handedness by EEPROM
 
 This method sets the keyboard's handedness by setting a flag in the persistent storage (`EEPROM`).  This is checked when the controller first starts up, and determines what half the keyboard is, and how to orient the keyboard layout.

 Plover can work with any standard QWERTY keyboard, although it is more efficient if the keyboard supports NKRO (n-key rollover) to allow Plover to see all the pressed keys at once. An example keymap for Plover can be found in `planck/keymaps/default`. Switching to the `PLOVER` layer adjusts the position of the keyboard to support the number bar.
 
 To use Plover with QMK just enable NKRO and optionally adjust your layout if you have anything other than a standard layout. You may also want to purchase some steno-friendly keycaps to make it easier to hit multiple keys.

 In your keymap create a new layer for Plover. You will need to include `keymap_steno.h`. See `planck/keymaps/steno/keymap.c` for an example. Remember to create a key to switch to the layer as well as a key for exiting the layer. If you would like to switch modes on the fly you can use the keycodes `QK_STENO_BOLT` and `QK_STENO_GEMINI`. If you only want to use one of the protocols you may set it up in your initialization function:

 # Tap Dance: A Single Key Can Do 3, 5, or 100 Different Things
 
-## Introduction
+## Introduction :id=introduction
+
 Hit the semicolon key once, send a semicolon. Hit it twice, rapidly -- send a colon. Hit it three times, and your keyboard's LEDs do a wild dance. That's just one example of what Tap Dance can do. It's one of the nicest community-contributed features in the firmware, conceived and created by [algernon](https://github.com/algernon) in [#451](https://github.com/qmk/qmk_firmware/pull/451). Here's how algernon describes the feature:
 
 With this feature one can specify keys that behave differently, based on the amount of times they have been tapped, and when interrupted, they get handled before the interrupter.
 
-## Explanatory Comparison with `ACTION_FUNCTION_TAP`
-`ACTION_FUNCTION_TAP` can offer similar functionality to Tap Dance, but it's worth noting some important differences. To do this, let's explore a certain setup! We want one key to send `Space` on single-tap, but `Enter` on double-tap.
+## How to Use Tap Dance :id=how-to-use
 
-With `ACTION_FUNCTION_TAP`, it is quite a rain-dance to set this up, and has the problem that when the sequence is interrupted, the interrupting key will be sent first. Thus, `SPC a` will result in `a SPC` being sent, if `SPC` and `a` are both typed within `TAPPING_TERM`. With the Tap Dance feature, that'll come out correctly as `SPC a` (even if both `SPC` and `a` are typed within the `TAPPING_TERM`.
-
-To achieve this correct handling of interrupts, the implementation of Tap Dance hooks into two parts of the system: `process_record_quantum()`, and the matrix scan. These two parts are explained below, but for now the point to note is that we need the latter to be able to time out a tap sequence even when a key is not being pressed. That way, `SPC` alone will time out and register after `TAPPING_TERM` time.
-
-## How to Use Tap Dance
-But enough of the generalities; lets look at how to actually use Tap Dance!
-
-First, you will need `TAP_DANCE_ENABLE=yes` in your `rules.mk`, because the feature is disabled by default. This adds a little less than 1k to the firmware size. 
+First, you will need `TAP_DANCE_ENABLE = yes` in your `rules.mk`, because the feature is disabled by default. This adds a little less than 1k to the firmware size. 
 
 Optionally, you might want to set a custom `TAPPING_TERM` time by adding something like this in you `config.h`:
 
-```
+```c
 #define TAPPING_TERM 175
 ```
 
-The `TAPPING_TERM` time is the maximum time allowed between taps of your Tap Dance key, and is measured in milliseconds. For example, if you used the above `#define` statement and set up a Tap Dance key that sends `Space` on single-tap and `Enter` on double-tap, then this key will send `ENT` only if you tap this key twice in less than 175ms. If you tap the key, wait more than 175ms, and tap the key again you'll end up sending `SPC SPC` instead.

 Well, that's the bulk of it! You should now be able to work through the examples below, and to develop your own Tap Dance functionality. But if you want a deeper understanding of what's going on behind the scenes, then read on for the explanation of how it all works!
 
 The main entry point is `process_tap_dance()`, called from `process_record_quantum()`, which is run for every keypress, and our handler gets to run early. This function checks whether the key pressed is a tap-dance key. If it is not, and a tap-dance was in action, we handle that first, and enqueue the newly pressed key. If it is a tap-dance key, then we check if it is the same as the already active one (if there's one active, that is). If it is not, we fire off the old one first, then register the new one. If it was the same, we increment the counter and reset the timer.

 For the sake of flexibility, tap-dance actions can be either a pair of keycodes, or a user function. The latter allows one to handle higher tap counts, or do extra things, like blink the LEDs, fiddle with the backlighting, and so on. This is accomplished by using an union, and some clever macros.

-### Lower and Upper Case
+#### Lower and Upper Case
 
 Characters often come in lower and upper case pairs, such as å and Å. To make inputting these characters easier, you can use `XP(i, j)` in your keymap, where _i_ and _j_ are the mapping table indices of the lower and upper case character, respectively. If you're holding down Shift or have Caps Lock turned on when you press the key, the second (upper case) character will be inserted; otherwise, the first (lower case) version will appear.
 
 This is most useful when creating a keymap for an international layout with special characters. Instead of having to put the lower and upper case versions of a character on separate keys, you can have them both on the same key by using `XP()`. This helps blend Unicode keys in with regular alphas.
 
-Due to keycode size constraints, _i_ and _j_ can each only refer to one of the first 128 characters in your `unicode_map`. In other words, 0 ≤ _i_ ≤ 127 and 0 ≤ _j_ ≤ 127. This is enough for most use cases, but if you'd like to customize the index calculation, you can override the [`unicodemap_index()`](https://github.com/qmk/qmk_firmware/blob/71f640d47ee12c862c798e1f56392853c7b1c1a8/quantum/process_keycode/process_unicodemap.c#L40) function.

-## Input Modes
+
+## 2. Input Modes :id=input-modes
 
 Unicode input in QMK works by inputting a sequence of characters to the OS, sort of like a macro. Unfortunately, the way this is done differs for each platform. Specifically, each platform requires a different combination of keys to trigger Unicode input. Therefore, a corresponding input mode has to be set in QMK.
 
 The following input modes are available:
 
-* **`UC_OSX`**: macOS built-in Unicode hex input. Supports code points up to `0xFFFF` (`0x10FFFF` with Unicode Map).
+* **`UC_MAC`**: macOS built-in Unicode hex input. Supports code points up to `0x10FFFF` (all possible code points).
 
   To enable, go to _System Preferences > Keyboard > Input Sources_, add _Unicode Hex Input_ to the list (it's under _Other_), then activate it from the input dropdown in the Menu Bar.
-  By default, this mode uses the left Option key (`KC_LALT`) for Unicode input, but this can be changed by defining [`UNICODE_KEY_OSX`](#input-key-configuration) with another keycode.
+  By default, this mode uses the left Option key (`KC_LALT`) for Unicode input, but this can be changed by defining [`UNICODE_KEY_MAC`](#input-key-configuration) with a different keycode.

+  !> Using the _Unicode Hex Input_ input source may disable some Option-based shortcuts, such as Option+Left and Option+Right.
+
+  !> `UC_OSX` is a deprecated alias of `UC_MAC` that will be removed in future versions of QMK. All new keymaps should use `UC_MAC`.
 
 * **`UC_LNX`**: Linux built-in IBus Unicode input. Supports code points up to `0x10FFFF` (all possible code points).
 
   Enabled by default and works almost anywhere on IBus-enabled distros. Without IBus, this mode works under GTK apps, but rarely anywhere else.
-  By default, this mode uses Ctrl+Shift+U (`LCTL(LSFT(KC_U))`) to start Unicode input, but this can be changed by defining [`UNICODE_KEY_LNX`](#input-key-configuration) with another keycode. This might be required for IBus versions ≥1.5.15, where Ctrl+Shift+U behavior is consolidated into Ctrl+Shift+E.

 * **`UC_WIN`**: _(not recommended)_ Windows built-in hex numpad Unicode input. Supports code points up to `0xFFFF`.
 
-  To enable, create a registry key under `HKEY_CURRENT_USER\Control Panel\Input Method\EnableHexNumpad` of type `REG_SZ` called `EnableHexNumpad` and set its value to `1`. This can be done from the Command Prompt by running `reg add "HKCU\Control Panel\Input Method" -v EnableHexNumpad -t REG_SZ -d 1` with administrator privileges. Reboot afterwards.

This can be done from the Command Prompt by running `reg add "HKCU\Control Panel\Input Method" -v EnableHexNumpad -t REG_SZ -d 1` with administrator privileges. Reboot afterwards.
   This mode is not recommended because of reliability and compatibility issues; use the `UC_WINC` mode instead.
 
 * **`UC_BSD`**: _(non implemented)_ Unicode input under BSD. Not implemented at this time. If you're a BSD user and want to help add support for it, please [open an issue on GitHub](https://github.com/qmk/qmk_firmware/issues).
 
 * **`UC_WINC`**: Windows Unicode input using [WinCompose](https://github.com/samhocevar/wincompose). As of v0.9.0, supports code points up to `0x10FFFF` (all possible code points).
 
-  To enable, install the [latest release](https://github.com/samhocevar/wincompose/releases/latest). Once installed, WinCompose will automatically run on startup. Works reliably under all version of Windows supported by the app.
-  By default, this mode uses right Alt (`KC_RALT`) as the Compose key, but this can be changed in the WinCompose settings and by defining [`UNICODE_KEY_WINC`](#input-key-configuration) with another keycode.

-### Switching Input Modes
 
-There are two ways to set the input mode for Unicode: by keycode or by function. Keep in mind that both methods write to persistent storage (EEPROM), and are loaded each time the keyboard starts. So once you've set it the first time, you don't need to set it again unless you want to change it, or you've reset the EEPROM settings.
+## 3. Setting the Input Mode :id=setting-the-input-mode
 
-You can switch the input mode at any time by using one of the following keycodes. The easiest way is to add the ones you use to your keymap.
-
-|Keycode               |Alias    |Input Mode  |Description                                                   |
-|----------------------|---------|------------|--------------------------------------------------------------|
-|`UNICODE_MODE_FORWARD`|`UC_MOD` |Next in list|[Cycle](#input-mode-cycling) through selected modes           |
-|`UNICODE_MODE_REVERSE`|`UC_RMOD`|Prev in list|[Cycle](#input-mode-cycling) through selected modes in reverse|
-|`UNICODE_MODE_OSX`    |`UC_M_OS`|`UC_OSX`    |Switch to macOS input                                         |
-|`UNICODE_MODE_LNX`    |`UC_M_LN`|`UC_LNX`    |Switch to Linux input                                         |
-|`UNICODE_MODE_WIN`    |`UC_M_WI`|`UC_WIN`    |Switch to Windows input                                       |
-|`UNICODE_MODE_BSD`    |`UC_M_BS`|`UC_BSD`    |Switch to BSD input (not implemented)                         |
-|`UNICODE_MODE_WINC`   |`UC_M_WC`|`UC_WINC`   |Switch to Windows input using WinCompose                      |
-
-You can also switch the input mode by calling `set_unicode_input_mode(x)` in your code, where _x_ is one of the above input mode constants (e.g. `UC_LNX`). Since the function only needs to be called once, it's recommended that you do it in `eeconfig_init_user()` (or a similar function). For example:
+To set your desired input mode, add the following define to your `config.h`:
 
 ```c
-void eeconfig_init_user(void) {
-    set_unicode_input_mode(UC_LNX);
-}
+#define UNICODE_SELECTED_MODES UC_LNX
 ```
 
-### Audio Feedback
+This example sets the board's default input mode to `UC_LNX`. You can replace this with `UC_MAC`, `UC_WINC`, or any of the other modes listed [above](#input-modes). The board will automatically use the selected mode on startup, unless you manually switch to another mode (see [below](#keycodes)).
+
+You can also select multiple input modes, which allows you to easily cycle through them using the `UC_MOD`/`UC_RMOD` keycodes.
+
+```c
+#define UNICODE_SELECTED_MODES UC_MAC, UC_LNX, UC_WINC
+```
+
+Note that the values are separated by commas. The board will remember the last used input mode and will continue using it on next power-up. You can disable this and force it to always start with the first mode in the list by adding `#define UNICODE_CYCLE_PERSIST false` to your `config.h`.
+
+#### Keycodes
+
+You can switch the input mode at any time by using the following keycodes. Adding these to your keymap allows you to quickly switch to a specific input mode, including modes not listed in `UNICODE_SELECTED_MODES`.
+
+|Keycode               |Alias    |Input Mode  |Description                                                                  |

+|`UNICODE_MODE_MAC`    |`UC_M_MA`|`UC_MAC`    |Switch to macOS input                                                        |
+|`UNICODE_MODE_LNX`    |`UC_M_LN`|`UC_LNX`    |Switch to Linux input                                                        |
+|`UNICODE_MODE_WIN`    |`UC_M_WI`|`UC_WIN`    |Switch to Windows input                                                      |
+|`UNICODE_MODE_BSD`    |`UC_M_BS`|`UC_BSD`    |Switch to BSD input _(not implemented)_                                      |
+|`UNICODE_MODE_WINC`   |`UC_M_WC`|`UC_WINC`   |Switch to Windows input using WinCompose                                     |
+
+You can also switch the input mode by calling `set_unicode_input_mode(x)` in your code, where _x_ is one of the above input mode constants (e.g. `UC_LNX`).
+
+?> Using `UNICODE_SELECTED_MODES` is preferable to calling `set_unicode_input_mode()` in `matrix_init_user()` or similar functions, since it's better integrated into the Unicode system and has the added benefit of avoiding unnecessary writes to EEPROM.
+
+#### Audio Feedback
 
 If you have the [Audio feature](feature_audio.md) enabled on the board, you can set melodies to be played when you press the above keys. That way you can have some audio feedback when switching input modes.
 
 For instance, you can add these definitions to your `config.h` file:
 
 ```c
-#define UNICODE_SONG_OSX  COIN_SOUND
+#define UNICODE_SONG_MAC  AUDIO_ON_SOUND
 #define UNICODE_SONG_LNX  UNICODE_LINUX
-#define UNICODE_SONG_BSD  MARIO_GAMEOVER
+#define UNICODE_SONG_BSD  TERMINAL_SOUND
 #define UNICODE_SONG_WIN  UNICODE_WINDOWS
 #define UNICODE_SONG_WINC UNICODE_WINDOWS
 ```
 
-### Additional Customization
+
+## Additional Customization
 
 Because Unicode is a large and versatile feature, there are a number of options you can customize to make it work better on your system.
 
-#### Start and Finish Input Functions
+### Start and Finish Input Functions
 
 The functions for starting and finishing Unicode input on your platform can be overridden locally. Possible uses include customizing input mode behavior if you don't use the default keys, or adding extra visual/audio feedback to Unicode input.
 
-* `void unicode_input_start(void)` – This sends the initial sequence that tells your platform to enter Unicode input mode. For example, it presses Ctrl+Shift+U on Linux and holds the Option key on macOS.
-* `void unicode_input_finish(void)` – This is called to exit Unicode input mode, for example by pressing Space or releasing the Option key.
+* `void unicode_input_start(void)` – This sends the initial sequence that tells your platform to enter Unicode input mode. For example, it holds the left Alt key followed by Num+ on Windows, and presses the `UNICODE_KEY_LNX` combination (default: Ctrl+Shift+U) on Linux.
+* `void unicode_input_finish(void)` – This is called to exit Unicode input mode, for example by pressing Space or releasing the Alt key.
 
 You can find the default implementations of these functions in [`process_unicode_common.c`](https://github.com/qmk/qmk_firmware/blob/master/quantum/process_keycode/process_unicode_common.c).
 
-#### Input Key Configuration
+### Input Key Configuration
 
 You can customize the keys used to trigger Unicode input for macOS, Linux and WinCompose by adding corresponding defines to your `config.h`. The default values match the platforms' default settings, so you shouldn't need to change this unless Unicode input isn't working, or you want to use a different key (e.g. in order to free up left or right Alt).
 
 |Define            |Type      |Default           |Example                                    |
 |------------------|----------|------------------|-------------------------------------------|
-|`UNICODE_KEY_OSX` |`uint8_t` |`KC_LALT`         |`#define UNICODE_KEY_OSX  KC_RALT`         |
+|`UNICODE_KEY_MAC` |`uint8_t` |`KC_LALT`         |`#define UNICODE_KEY_MAC  KC_RALT`         |
 |`UNICODE_KEY_LNX` |`uint16_t`|`LCTL(LSFT(KC_U))`|`#define UNICODE_KEY_LNX  LCTL(LSFT(KC_E))`|
 |`UNICODE_KEY_WINC`|`uint8_t` |`KC_RALT`         |`#define UNICODE_KEY_WINC KC_RGUI`         |
 
-#### Input Mode Cycling
 
-You can choose which input modes are available for cycling through. By default, this is disabled. If you want to enable it, limiting it to just the modes you use makes sense. Note that the values in the list are comma-delimited.
+## Sending Unicode Strings
+
+QMK provides several functions that allow you to send Unicode input to the host programmatically:
+
+### `send_unicode_string()`
+
+This function is much like `send_string()`, but it allows you to input UTF-8 characters directly. It supports all code points, provided the selected input mode also supports it. Make sure your `keymap.c` file is formatted using UTF-8 encoding.
 
 ```c
-#define UNICODE_SELECTED_MODES UC_OSX, UC_LNX, UC_WIN, UC_WINC
+send_unicode_string("(ノಠ痊ಠ)ノ彡┻━┻");
 ```
 
-You can cycle through the selected modes by using the `UC_MOD`/`UC_RMOD` keycodes, or by calling `cycle_unicode_input_mode(offset)` in your code (`offset` is how many modes to move forward by, so +1 corresponds to `UC_MOD`).
+Example uses include sending Unicode strings when a key is pressed, as described in [Macros](feature_macros.md).
 
-By default, when the keyboard boots, it will initialize the input mode to the last one you used. You can disable this and make it start with the first mode in the list every time by adding the following to your `config.h`:
+### `send_unicode_hex_string()`
+
+Similar to `send_unicode_string()`, but the characters are represented by their Unicode code points, written in hexadecimal and separated by spaces. For example, the table flip above would be achieved with:
 
 ```c
-#define UNICODE_CYCLE_PERSIST false
+send_unicode_hex_string("0028 30CE 0CA0 75CA 0CA0 0029 30CE 5F61 253B 2501 253B");
 ```
 
-!> Using `UNICODE_SELECTED_MODES` means you don't have to initially set the input mode in `matrix_init_user()` (or a similar function); the Unicode system will do that for you on startup. This has the added benefit of avoiding unnecessary writes to EEPROM.
+An easy way to convert your Unicode string to this format is to use [this site](https://r12a.github.io/app-conversion/) and take the result in the "Hex/UTF-32" section.
 
-## `send_unicode_hex_string`
-
-To type multiple characters for things like (ノಠ痊ಠ)ノ彡┻━┻, you can use `send_unicode_hex_string()` much like `SEND_STRING()` except you would use hex values separate by spaces.
-For example, the table flip seen above would be `send_unicode_hex_string("0028 30CE 0CA0 75CA 0CA0 0029 30CE 5F61 253B 2501 253B")`
-
-There are many ways to get a hex code, but an easy one is [this site](https://r12a.github.io/app-conversion/). Just make sure to convert to hexadecimal, and that is your string.
 
 ## Additional Language Support
 
-In `quantum/keymap_extras/`, you'll see various language files - these work the same way as the alternative layout ones do. Most are defined by their two letter country/language code followed by an underscore and a 4-letter abbreviation of its name. `FR_UGRV` which will result in a `ù` when using a software-implemented AZERTY layout. It's currently difficult to send such characters in just the firmware.
+In `quantum/keymap_extras`, you'll see various language files — these work the same way as the ones for alternative layouts such as Colemak or BÉPO. When you include one of these language headers, you gain access to keycodes specific to that language / national layout. Such keycodes are defined by a 2-letter country/language code, followed by an underscore and a 4-letter abbreviation of the character to which the key corresponds. For example, including `keymap_french.h` and using `FR_UGRV` in your keymap will output `ù` when typed on a system with a native French AZERTY layout.
+
+If the primary system layout you use on your machine is different from US ANSI, using these language-specific keycodes can help your QMK keymaps better match what will actually be output on the screen. However, keep in mind that these keycodes are just aliases for the corresponding default US keycodes under the hood, and that the HID protocol used by keyboards is itself inherently based on US ANSI.

 # Flashing Instructions and Bootloader Information
 
-There are quite a few different types of bootloaders that keyboards use, and just about all of the use a different flashing method. Luckily, projects like the [QMK Toolbox](https://github.com/qmk/qmk_toolbox/releases) aim to be compatible with all the different types without having to think about it much, but this article will describe the different types of bootloaders, and available methods for flashing them.

-If you have a bootloader selected with the `BOOTLOADER` variable in your `rules.mk`, QMK will automatically calculate if your .hex file is the right size to be flashed to the device, and output the total size in bytes (along with the max). To run this process manually, compile with the target `check-size`, eg `make planck/rev4:default:check-size`.
