+
+### Setting Handedness
+
+One thing to remember, the side that the USB port is plugged into is always the master half. The side not plugged into USB is the slave.
+
+There are a few different ways to set handedness for split keyboards (listed in order of precedence):
+
+1. Set `SPLIT_HAND_PIN`: Reads a pin to determine handedness. If pin is high, it's the left side, if low, the half is determined to be the right side
+2. Set `EE_HANDS` and flash `eeprom-lefthand.eep`/`eeprom-righthand.eep` to each half
+   * For boards with DFU bootloader you can use `:dfu-split-left`/`:dfu-split-right` to flash these EEPROM files
+   * For boards with Caterina bootloader (like stock Pro Micros), use `:avrdude-split-left`/`:avrdude-split-right`
+3. Set `MASTER_RIGHT`: Half that is plugged into the USB port is determined to be the master and right half (inverse of the default)
+4. Default: The side that is plugged into the USB port is the master half and is assumed to be the left half. The slave side is the right half
+
+#### Defines for handedness
+
 * `#define SPLIT_HAND_PIN B7`
-  * For using high/low pin to determine handedness, low = right hand, high = left hand. Replace 'B7' with the pin you are using. This is optional and you can still use the EEHANDS method or MASTER_LEFT / MASTER_RIGHT defines like the stock Let's Split uses.
-  
+  * For using high/low pin to determine handedness, low = right hand, high = left hand. Replace `B7` with the pin you are using. This is optional, and if you leave `SPLIT_HAND_PIN` undefined, then you can still use the EE_HANDS method or MASTER_LEFT / MASTER_RIGHT defines like the stock Let's Split uses.
+
+* `#define EE_HANDS` (only works if `SPLIT_HAND_PIN` is not defined)
+  * Reads the handedness value stored in the EEPROM after `eeprom-lefthand.eep`/`eeprom-righthand.eep` has been flashed to their respective halves.
+
+* `#define MASTER_RIGHT`
+  * Master half is defined to be the right half.
+
+### Other Options
+
 * `#define USE_I2C`
   * For using I2C instead of Serial (defaults to serial)
 
+* `#define SOFT_SERIAL_PIN D0`
+  * When using serial, define this. `D0` or `D1`,`D2`,`D3`,`E6`.
+
+* `#define MATRIX_ROW_PINS_RIGHT { <row pins> }`
+* `#define MATRIX_COL_PINS_RIGHT { <col pins> }`
+  * If you want to specify a different pinout for the right half than the left half, you can define `MATRIX_ROW_PINS_RIGHT`/`MATRIX_COL_PINS_RIGHT`. Currently, the size of `MATRIX_ROW_PINS` must be the same as `MATRIX_ROW_PINS_RIGHT` and likewise for the definition of columns.
+
+* `#define SELECT_SOFT_SERIAL_SPEED <speed>` (default speed is 1)
+  * Sets the protocol speed when using serial communication
+  * Speeds:
+    * 0: about 189kbps (Experimental only)

+
+## USB Endpoint Limitations
+
+In order to provide services over USB, QMK has to use USB endpoints.
+These are a finite resource: each microcontroller has only a certain number.
+This limits what features can be enabled together.
+If the available endpoints are exceeded, a build error is thrown.
+
+The following features can require separate endpoints:
+
+* `MOUSEKEY_ENABLE`
+* `EXTRAKEY_ENABLE`
+* `CONSOLE_ENABLE`
+* `NKRO_ENABLE`
+* `MIDI_ENABLE`
+* `RAW_ENABLE`
+* `VIRTSER_ENABLE`
+
+In order to improve utilisation of the endpoints, the HID features can be combined to use a single endpoint.
+By default, `MOUSEKEY`, `EXTRAKEY`, and `NKRO` are combined into a single endpoint.
+
+The base keyboard functionality can also be combined into the endpoint,
+by setting `KEYBOARD_SHARED_EP = yes`.
+This frees up one more endpoint,
+but it can prevent the keyboard working in some BIOSes,
+as they do not implement Boot Keyboard protocol switching.
+
+Combining the mouse also breaks Boot Mouse compatibility.
+The mouse can be uncombined by setting `MOUSE_SHARED_EP = no` if this functionality is required.

+# Auto-formatting with clang-format
+
+[Clang-format](https://clang.llvm.org/docs/ClangFormat.html) is part of LLVM and can automatically format your code for you, because ain't nobody got time to do it manually. We supply a configuration file for it that applies most of the coding conventions listed above. It will only change whitespace and newlines, so you will still have to remember to include optional braces yourself.
+
+Use the [full LLVM installer](http://llvm.org/builds/) to get clang-format on Windows, or use `sudo apt install clang-format` on Ubuntu.
+
+If you run it from the command-line, pass `-style=file` as an option and it will automatically find the .clang-format configuration file in the QMK root directory.
+
+If you use VSCode, the standard C/C++ plugin supports clang-format, alternatively there is a [separate extension](https://marketplace.visualstudio.com/items?itemName=LLVMExtensions.ClangFormat) for it.
+
+Some things (like LAYOUT macros) are destroyed by clang-format, so either don't run it on those files, or wrap the sensitive code in `// clang-format off` and `// clang-format on`.

-# Matrix Initialization Code
+Call this function to get the last received LED state. This is useful for reading the LED state outside `led_set_*`, e.g. in [`matrix_scan_user()`](#matrix-scanning-code).
+For convenience, you can use the `IS_HOST_LED_ON(led_name)` and `IS_HOST_LED_OFF(led_name)` macros instead of calling and checking `host_keyboard_leds()` directly.
 
-Before a keyboard can be used the hardware must be initialized. QMK handles initialization of the keyboard matrix itself, but if you have other hardware like LED's or i&#xb2;c controllers you will need to set up that hardware before it can be used.
+## Setting Physical LED State
 
+Some keyboard implementations provide convenience methods for setting the state of the physical LEDs.
 
-### Example `matrix_init_user()` Implementation
+### Ergodox Boards
 
-This example, at the keyboard level, sets up B1, B2, and B3 as LED pins.
+The Ergodox implementations provide `ergodox_right_led_1`/`2`/`3_on`/`off()` to turn individual LEDs on or off, as well as `ergodox_right_led_on`/`off(uint8_t led)` to turn them on or off by their index.
+
+In addition, it is possible to specify the brightness level of all LEDs with `ergodox_led_all_set(uint8_t n)`; of individual LEDs with `ergodox_right_led_1`/`2`/`3_set(uint8_t n)`; or by index with `ergodox_right_led_set(uint8_t led, uint8_t n)`.
+
+Ergodox boards also define `LED_BRIGHTNESS_LO` for the lowest brightness and `LED_BRIGHTNESS_HI` for the highest brightness (which is the default).
+
+# Keyboard Initialization Code
+
+There are several steps in the keyboard initialization process.  Depending on what you want to do, it will influence which function you should use.
+
+These are the three main initialization functions, listed in the order that they're called.
+
+* `keyboard_pre_init_*` - Happens before most anything is started. Good for hardware setup that you want running very early.
+* `matrix_init_*` - Happens midway through the firmware's startup process. Hardware is initialized, but features may not be yet.
+* `keyboard_post_init_*` - Happens at the end of the firmware's startup process. This is where you'd want to put "customization" code, for the most part.
+
+!> For most people, the `keyboard_post_init_user` function is what you want to call.  For instance, this is where you want to set up things for RGB Underglow.
+
+## Keyboard Pre Initialization code
+
+This runs very early during startup, even before the USB has been started. 
+
+Shortly after this, the matrix is initialized.
+
+For most users, this shouldn't be used, as it's primarily for hardware oriented initialization. 
+
+However, if you have hardware stuff that you need initialized, this is the best place for it (such as initializing LED pins).
+
+### Example `keyboard_pre_init_user()` Implementation
+
+This example, at the keyboard level, sets up B0, B1, B2, B3, and B4 as LED pins.
 
 ```c
-void matrix_init_user(void) {

+## Callbacks
 
-# Permissive Hold
+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.

-    #define PITCH_STANDARD_A 432.0f
+By default, the Music Mode uses the columns and row to determine the scale for the keys. For a board that uses a rectangular matrix that matches the keyboard layout, this is just fine.  However, for boards that use a more complicated matrix (such as the Planck Rev6, or many split keyboards) this would result in a very skewed experience.  
 
-You can completely disable Music Mode as well. This is useful, if you're pressed for space on your controller.  To disable it, add this to your `config.h`:
+However, the Music Map option allows you to remap the scaling for the music mode, so it fits the layout, and is more natural. 
 
-    #define NO_MUSIC_MODE
+To enable this feature, add `#define MUSIC_MAP` to your `config.h` file, and then you will want to add a `uint8_t music_map` to your keyboard's `c` file, or your `keymap.c`.
+
+```c

+	 0,  1,  2,  3,  4,  5,  6,  7,  8,  9, 10, 11
+);
+```
+
+You will want to use whichever `LAYOUT` macro that your keyboard uses here.  This maps it to the correct key location.  Start in  the bottom left of the keyboard layout, and  move to the right, and then upwards.  Fill in all the entries until you have a complete matrix.

+You can look at the [Planck Keyboard](https://github.com/qmk/qmk_firmware/blob/e9ace1487887c1f8b4a7e8e6d87c322988bec9ce/keyboards/planck/planck.c#L24-L29) as an example of how to implement this.

+| anything_else    | Use another algorithm from quantum/debounce/*        | Nothing                       |
+
+**Regarding split keyboards**:
+The debounce code is compatible with split keyboards.
+
+# Use your own debouncing code
+* Set ```DEBOUNCE_TYPE = custom ```.
+* Add ```SRC += debounce.c```
+* Add your own ```debounce.c```. Look at current implementations in ```quantum/debounce``` for examples.
+* Debouncing occurs after every raw matrix scan.
+* Use num_rows rather than MATRIX_ROWS, so that split keyboards are supported correctly.
+
+# Changing between included debouncing methods
+You can either use your own code, by including your own debounce.c, or switch to another included one.
+Included debounce methods are:
+* eager_pk - debouncing per key. On any state change, response is immediate, followed by ```DEBOUNCE_DELAY``` millseconds of no further input for that key
+* sym_g - debouncing per keyboard. On any state change, a global timer is set. When ```DEBOUNCE_DELAY``` milliseconds of no changes has occured, all input changes are pushed.

+
+### Solenoids
+
+First you will need a build a circuit to drive the solenoid through a mosfet as most MCU will not be able to provide the current needed to drive the coil in the solenoid.
+
+[Wiring diagram provided by Adafruit](https://playground.arduino.cc/uploads/Learning/solenoid_driver.pdf)
+
+Select a pin that has PWM for the signal pin
+
+```
+#define SOLENOID_PIN *pin*
+```
+
+Beware that some pins may be powered during bootloader (ie. A13 on the STM32F303 chip) and will result in the solenoid kept in the on state through the whole flashing process. This may overheat and damage the solenoid. If you find that the pin the solenoid is connected to is triggering the solenoid during bootloader/DFU, select another pin.
+
+### DRV2605L
+
+DRV2605L is controlled over i2c protocol, and has to be connected to the SDA and SCL pins, these varies depending on the MCU in use.
+
+#### Feedback motor setup
+
+This driver supports 2 different feedback motors. Set the following in your `config.h` based on which motor you have selected.
+
+##### ERM
+
+Eccentric Rotating Mass vibration motors (ERM) is motor with a off-set weight attached so when drive signal is attached, the off-set weight spins and causes a sinusoidal wave that translate into vibrations.
+
+```
+#define FB_ERM_LRA 0
+#define FB_BRAKEFACTOR 3 /* For 1x:0, 2x:1, 3x:2, 4x:3, 6x:4, 8x:5, 16x:6, Disable Braking:7 */
+#define FB_LOOPGAIN 1 /* For  Low:0, Medium:1, High:2, Very High:3 */
+
+/* Please refer to your datasheet for the optimal setting for your specific motor. */
+#define RATED_VOLTAGE 3
+#define V_PEAK 5
+```
+##### LRA
+
+Linear resonant actuators (LRA, also know as a linear vibrator) works different from a ERM. A LRA has a weight and magnet suspended by springs and a voice coil. When the drive signal is applied, the weight would be vibrate on a single axis (side to side or up and down). Since the weight is attached to a spring, there is a resonance effect at a specific frequency. This frequency is where the LRA will operate the most efficiently. Refer to the motor's datasheet for the recommanded range for this frequency.
+
+``` 
+#define FB_ERM_LRA 1
+#define FB_BRAKEFACTOR 3 /* For 1x:0, 2x:1, 3x:2, 4x:3, 6x:4, 8x:5, 16x:6, Disable Braking:7 */
+#define FB_LOOPGAIN 1 /* For  Low:0, Medium:1, High:2, Very High:3 */
+
+/* Please refer to your datasheet for the optimal setting for your specific motor. */
+#define RATED_VOLTAGE 2
+#define V_PEAK 2.8
+#define V_RMS 2.0 
+#define V_PEAK 2.1
+#define F_LRA 205 /* resonance freq */
+```
+
+#### DRV2605L waveform library
+
+DRV2605L comes with preloaded library of various waveform sequences that can be called and played. If writing a macro, these waveforms can be played using `DRV_pulse(*sequence name or number*)`
+

Specifically, when you press the `KC_LEAD` key, you only have a certain amount of time to complete the Leader Key sequence.  The `300` here sets that to 300ms, and you can increase this value to give you more time to hit the sequence. But any keys pressed during this timeout are intercepted and not sent, so you may want to keep this value low. .

 To add support for Leader Key you simply need to add a single line to your keymap's `rules.mk`:
 
-```
+```make
 LEADER_ENABLE = yes
 ```
+
+## Per Key Timing on Leader keys
+
+Rather than relying on an incredibly high timeout for long leader key strings or those of us without 200wpm typing skills, we can enable per key timing to ensure that each key pressed provides us with more time to finish our stroke. This is incredibly helpful with leader key emulation of tap dance (read: multiple taps of the same key like C, C, C).
+
+In order to enable this, place this in your `config.h`:
+```c
+#define LEADER_PER_KEY_TIMING
+```
+
+After this, it's recommended that you lower your `LEADER_TIMEOUT` to something less that 300ms.
+
+```c
+#define LEADER_TIMEOUT 250
+```
+
+Now, something like this won't seem impossible to do without a 1000MS leader key timeout:
+
+```c
+SEQ_THREE_KEYS(KC_C, KC_C, KC_C) {
+  SEND_STRING("Per key timing is great!!!");
+}
+```
+
+## Strict Key Processing
+
+By default, the Leader Key feature will filter the keycode out of [`Mod-Tap`](feature_advanced_keycodes.md#mod-tap) and [`Layer Tap`](feature_advanced_keycodes.md#switching-and-toggling-layers) functions when checking for the Leader sequences. That means if you're using `LT(3, KC_A)`, it will pick this up as `KC_A` for the sequence, rather than `LT(3, KC_A)`, giving a more expected behavior for newer users.
+
+While, this may be fine for most, if you want to specify the whole keycode (eg, `LT(3, KC_A)` from the example above) in the sequence, you can enable this by added `#define LEADER_KEY_STRICT_KEY_PROCESSING` to your `config.h` file.  This well then disable the filtering, and you'll need to specify the whole keycode.
+
+## Customization 
+
+The Leader Key feature has some additional customization to how the Leader Key feature works.  It has two functions that can be called at certain parts of the process.  Namely `leader_start()` and `leader_end()`.
+
+The `leader_start()` function is called when you tap the `KC_LEAD` key, and the `leader_end()` function is called when either the leader sequence is completed, or the leader timeout is hit. 
+
+You can add these functions to your code (`keymap.c` usually) to add feedback to the Leader sequences (such as beeping or playing music).
+
+```c
+void leader_start(void) {
+  // sequence started
+}
+
+void leader_end(void) {
+  // sequence ended (no success/failuer detection)
+}
+```
+
+### Example
+
+This example will play the Mario "One Up" sound when you hit `KC_LEAD` to start the Leader Sequence, and will play "All Star" if it completes successfully or "Rick Roll" you if it fails. 
+
+```c
+bool did_leader_succeed;
+#ifdef AUDIO_ENABLE

+# LED Matrix Lighting
+
+This feature allows you to use LED matrices driven by external drivers. It hooks into the backlight system so you can use the same keycodes as backlighting to control it.
+
+If you want to use RGB LED's you should use the [RGB Matrix Subsystem](feature_rgb_matrix.md) instead.
+
+## Driver configuration
+
+### IS31FL3731
+
+There is basic support for addressable LED matrix lighting with the I2C IS31FL3731 RGB controller. To enable it, add this to your `rules.mk`:
+
+    LED_MATRIX_ENABLE = IS31FL3731
+    
+You can use between 1 and 4 IS31FL3731 IC's. Do not specify `LED_DRIVER_ADDR_<N>` defines for IC's that are not present on your keyboard. You can define the following items in `config.h`:
+
+| Variable | Description | Default |
+|----------|-------------|---------|
+| `ISSI_TIMEOUT` | (Optional) How long to wait for i2c messages | 100 |
+| `ISSI_PERSISTENCE` | (Optional) Retry failed messages this many times | 0 |
+| `LED_DRIVER_COUNT` | (Required) How many LED driver IC's are present | |
+| `LED_DRIVER_LED_COUNT` | (Required) How many LED lights are present across all drivers | |
+| `LED_DRIVER_ADDR_1` | (Required) Address for the first LED driver | |
+| `LED_DRIVER_ADDR_2` | (Optional) Address for the second LED driver | |
+| `LED_DRIVER_ADDR_3` | (Optional) Address for the third LED driver | |
+| `LED_DRIVER_ADDR_4` | (Optional) Address for the fourth LED driver | |
+
+Here is an example using 2 drivers.
+
+	// This is a 7-bit address, that gets left-shifted and bit 0
+	// set to 0 for write, 1 for read (as per I2C protocol)
+	// The address will vary depending on your wiring:
+	// 0b1110100 AD <-> GND
+	// 0b1110111 AD <-> VCC
+	// 0b1110101 AD <-> SCL
+	// 0b1110110 AD <-> SDA
+	#define LED_DRIVER_ADDR_1 0b1110100
+	#define LED_DRIVER_ADDR_2 0b1110110
+
+	#define LED_DRIVER_COUNT 2
+	#define LED_DRIVER_1_LED_COUNT 25
+	#define LED_DRIVER_2_LED_COUNT 24
+	#define LED_DRIVER_LED_COUNT LED_DRIVER_1_LED_TOTAL + LED_DRIVER_2_LED_TOTAL
+
+Currently only 2 drivers are supported, but it would be trivial to support all 4 combinations.
+
+Define these arrays listing all the LEDs in your `<keyboard>.c`:
+
+	const is31_led g_is31_leds[DRIVER_LED_TOTAL] = {
+	/* Refer to IS31 manual for these locations
+	 *   driver
+	 *   |  LED address
+	 *   |  | */
+	    {0, C3_3},
+	    ....
+	}
+
+Where `Cx_y` is the location of the LED in the matrix defined by [the datasheet](http://www.issi.com/WW/pdf/31FL3731.pdf) and the header file `drivers/issi/is31fl3731-simple.h`. The `driver` is the index of the driver you defined in your `config.h` (`0`, `1`, `2`, or `3` ).
+
+## Keycodes
+
+All LED matrix keycodes are currently shared with the [backlight system](feature_backlight.md).
+
+## LED Matrix Effects
+
+Currently no LED matrix effects have been created.
+
+## Custom layer effects
+
+Custom layer effects can be done by defining this in your `<keyboard>.c`:
+
+    void led_matrix_indicators_kb(void) {
+        led_matrix_set_index_value(index, value);
+    }
+
+A similar function works in the keymap as `led_matrix_indicators_user`.
+
+## Suspended state
+
+To use the suspend feature, add this to your `<keyboard>.c`:
+
+	void suspend_power_down_kb(void)
+	{
+	    led_matrix_set_suspend_state(true);
+	}
+
+	void suspend_wakeup_init_kb(void)
+	{
+	    led_matrix_set_suspend_state(false);

+## Changing the order of the LEDs
+
+If you want to make the logical order of LEDs different from the electrical connection order, you can do this by defining the `RGBLIGHT_LED_MAP` macro in your `config.h`.
+
+By defining `RGBLIGHT_LED_MAP` as in the example below, you can specify the LED with addressing in reverse order of the electrical connection order.
+
+```c
+// config.h
+
+#define RGBLED_NUM 10
+#define RGBLIGHT_LED_MAP { 9, 8, 7, 6, 5, 4, 3, 2, 1, 0 }
+
+```
+
+For keyboards that use the RGB LEDs as a backlight for each key, you can also define it as in the example below.
+
+```c
+// config.h
+
+#define RGBLED_NUM 30
+
+/* RGB LED Conversion macro from physical array to electric array */
+#define LED_LAYOUT( \

 ## Hardware Modification
 
 If your keyboard lacks onboard underglow LEDs, you may often be able to solder on an RGB LED strip yourself. You will need to find an unused pin to wire to the data pin of your LED strip. Some keyboards may break out unused pins from the MCU to make soldering easier. The other two pins, VCC and GND, must also be connected to the appropriate power pins.

+### Example 5: Using tap dance for advanced mod-tap and layer-tap keys
+
+Tap dance can be used to emulate `MT()` and `LT()` behavior when the tapped code is not a basic keycode. This is useful to send tapped keycodes that normally require `Shift`, such as parentheses or curly braces—or other modified keycodes, such as `Control + X`.
+

+void altlp_finished (qk_tap_dance_state_t *state, void *user_data);
+void altlp_reset (qk_tap_dance_state_t *state, void *user_data);

+  if (state->count == 1) {

+
+## 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`**: Mac OS X built-in Unicode hex input. Supports code points up to `0xFFFF` (`0x10FFFF` with `UNICODEMAP`).
+
+  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`), but this can be changed by defining [`UNICODE_OSX_KEY`](#input-key-configuration) with another keycode.
+
+  **Note:** Using the _Unicode Hex Input_ input source may disable some Option based shortcuts, such as: Option + Left Arrow (`moveWordLeftAndModifySelection`) and Option + Right Arrow  (`moveWordRightAndModifySelection`).
+
+* **`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.
+
+* **`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. Afterwards, reboot.
+  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 v0.8.2, supports code points up to `0xFFFFF` (all currently assigned 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 the right Alt key (`KC_RALT`), but this can be changed in the WinCompose settings and by defining [`UNICODE_WINC_KEY`](#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.
+
+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` |             |Cycles forwards through the available modes. [(Disabled by default)](#input-method-cycling)|
+|`UNICODE_MODE_REVERSE` |`UC_RMOD`|             |Cycles forwards through the available modes. [(Disabled by default)](#input-method-cycling)|
+|`UNICODE_MODE_OSX`     |`UC_M_OS`|`UC_OSX`     |Switch to Mac OS X 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:
 
 ```c
-void qk_ucis_start_user(void) { // outputs keyboard emoji
-  unicode_input_start();
-  register_hex(0x2328);
-  unicode_input_finish();
-}
-
-void qk_ucis_success(uint8_t symbol_index) {
-}
-
-void qk_ucis_symbol_fallback (void) { // falls back to manual unicode entry
-  for (uint8_t i = 0; i < qk_ucis_state.count - 1; i++) {
-    uint8_t code = qk_ucis_state.codes[i];
-    register_code(code);
-    unregister_code(code);
-    wait_ms(UNICODE_TYPE_DELAY);
-  }
+void eeconfig_init_user(void) {
+  set_unicode_input_mode(UC_LNX);
 }
 ```
 
-## Unicode Input methods
+### Audio Feedback
 
-Unicode input in QMK works by inputting a sequence of characters to the OS,
-sort of like macro. Unfortunately, each OS has different ideas on how Unicode is input.
+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.
 
-This is the current list of Unicode input method in QMK:
+For instance, you can add these definitions to your `config.h` file:
 
-* __UC_OSX__: MacOS Unicode Hex Input support. Works only up to 0xFFFF. Disabled by default. To enable: go to System Preferences -> Keyboard -> Input Sources, and enable Unicode Hex.
-* __UC_OSX_RALT__: Same as UC_OSX, but sends the Right Alt key for unicode input
-* __UC_LNX__: Unicode input method under Linux. Works up to 0xFFFFF. Should work almost anywhere on ibus enabled distros. Without ibus, this works under GTK apps, but rarely anywhere else.
-* __UC_WIN__: (not recommended) Windows built-in Unicode input. To enable: create registry key under `HKEY_CURRENT_USER\Control Panel\Input Method\EnableHexNumpad` of type `REG_SZ` called `EnableHexNumpad`, set its value to 1, and reboot. This method is not recommended because of reliability and compatibility issue, use WinCompose method below instead.
-* __UC_WINC__: Windows Unicode input using WinCompose. Requires [WinCompose](https://github.com/samhocevar/wincompose). Works reliably under many (all?) variations of Windows.
+```c
+#define UNICODE_SONG_OSX  COIN_SOUND
+#define UNICODE_SONG_LNX  UNICODE_LINUX
+#define UNICODE_SONG_BSD  MARIO_GAMEOVER
+#define UNICODE_SONG_WIN  UNICODE_WINDOWS
+#define UNICODE_SONG_WINC UNICODE_WINDOWS
+```
 
-At some point, you need to call `set_unicode_input_mode(x)` to set the correct unicode method.  This sets the method that is used to send the unicode, and stores it in EEPROM, so you only need to call this once.
+### Additional Customization
+
+Because Unicode is such a large and variable feature, there are a number of options that you can customize to work better on your system.
+
+#### 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 Mac.
+* `void unicode_input_finish(void)` – This is called to exit Unicode input mode, for example by pressing Space or releasing the Option 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
+
+Additionally, you can customize the keys used to trigger the unicode input for macOS and WinCompose by adding defines to your `config.h`
+
+```c
+#define UNICODE_OSX_KEY  KC_LALT
+#define UNICODE_WINC_KEY KC_RALT
+```
+
+#### Input Method Cycling
+
+Also, you can choose which input methods are availble for cycling through.  By default, this is disabled. But if you want to enabled it, then limiting it to just those modes makes sense.  Note that `UNICODE_SELECTED_MODES` define is comma delimited.
+
+```c
+#define UNICODE_SELECTED_MODES UC_OSX, UC_LNX, UC_WIN, UC_BSD, UC_WINC

+For boards that may not have a shift button (such as on a macro pad), we need a way to always include the bootloader option.  To do that, add the following to the `rules.mk` in your userspace folder: 
+
+```make 
+ifeq ($(strip $(FLASH_BOOTLOADER)), yes)
+    OPT_DEFS += -DFLASH_BOOTLOADER
+endif
+```
+
 This will add a new `KC_MAKE` keycode that can be used in any of your keymaps.  And this keycode will output `make <keyboard>:<keymap>`, making frequent compiling easier.  And this will work with any keyboard and any keymap as it will output the current boards info, so that you don't have to type this out every time.
 
-Additionally, this should flash the newly compiled firmware automatically, using the correct utility, based on the bootloader settings (or default to just generating the HEX file). However, it should be noted that this may not work on all systems. AVRDUDE doesn't work on WSL, namely (and will dump the HEX in the ".build" folder instead).
+Also, holding `shift` will add the appropriate flashing command (`:dfu`, `:teensy`, `:avrdude`, `:dfu-util`) for a majority of keyboards.  Holding `control` will add some commands that will speed up compiling time by processing multiple files at once. 
 
+And for the boards that lack a shift key, or that you want to always attempt the flashing part, you can add `FLASH_BOOTLOADER = yes` to the `rules.mk` of that keymap.

+# Velocikey
+
+Velocikey is a feature that lets you control the speed of lighting effects (like the Rainbow Swirl effect) with the speed of your typing. The faster you type, the faster the lights will go!
+
+## Usage
+For Velocikey to take effect, there are two steps. First, when compiling your keyboard, you'll need to set `VELOCIKEY_ENABLE=yes` in `rules.mk`, e.g.:
+
+```
+BOOTMAGIC_ENABLE = no
+MOUSEKEY_ENABLE = no
+STENO_ENABLE = no
+EXTRAKEY_ENABLE = yes
+VELOCIKEY_ENABLE = yes
+```
+
+Then, while using your keyboard, you need to also turn it on with the VLK_TOG keycode, which toggles the feature on and off.
+
+The following light effects will all be controlled by Velocikey when it is enabled:
+ - RGB Breathing
+ - RGB Rainbow Mood
+ - RGB Rainbow Swirl
+ - RGB Snake
+ - RGB Knight
+
+Support for LED breathing effects is planned but not available yet.
+
+ As long as Velocikey is enabled, it will control the speed regardless of any other speed setting that your RGB lights are currently on.
+
+ ## Configuration
+ Velocikey doesn't currently support any configuration via keyboard settings. If you want to adjust something like the speed increase or decay rate, you would need to edit `velocikey.c` and adjust the values there to achieve the kinds of speeds that you like.

-We welcome all keyboard projects into QMK, but ask that you try to stick to a couple guidelines that help us keep things organised and consistent.
+Since starting, QMK has grown by leaps and bounds thanks to people like you who contribute to creating and maintaining our community keyboards. As we've grown we've discovered some patterns that work well, and ask that you conform to them to make it easier for other people to benefit from your hard work.
+
 
 ## Naming Your Keyboard/Project
 
-All names should be lowercase alphanumeric, and separated by an underscore (`_`), but not begin with one. Your directory and your `.h` and `.c` files should have exactly the same name. All folders should follow the same format. `test`, `keyboard`, and `all` are reserved by make and are not a valid name for a keyboard.
+All keyboard names are in lower case, consisting only of letters, numbers, and underscore (`_`). Names may not begin with an underscore. Forward slash (`/`) is used as a sub-folder separation character.
 
-## `readme.md`
+The names `test`, `keyboard`, and `all` are reserved for make commands and may not be used as a keyboard or subfolder name.
 
-All projects need to have a `readme.md` file that explains what the keyboard is, who made it, where it is available, and links to more information. Please follow the [published template](documentation_templates.md#keyboard-readmemd-template).
+Valid Examples:
+
+* `412_64`
+* `chimera_ortho`
+* `clueboard/66/rev3`
+* `planck`
+* `v60_type_r`
+
+## Sub-folders
+
+QMK uses sub-folders both for organization and to share code between revisions of the same keyboard. You can nest folders up to 4 levels deep:
+
+    qmk_firmware/keyboards/top_folder/sub_1/sub_2/sub_3/sub_4
+
+If a sub-folder has a `rules.mk` file it will be considered a compilable keyboard. It will be available in QMK Configurator and tested with `make all`. If you are using a folder to organize several keyboards from the same maker you should not have a `rules.mk` file.
+
+Example:
+
+Clueboard uses sub-folders for both purposes, organization and keyboard revisions.
+
+* [`qmk_firmware`](https://github.com/qmk/qmk_firmware/tree/master)
+  * [`keyboards`](https://github.com/qmk/qmk_firmware/tree/master/keyboards)

+## Keyboard Folder Structure
+
+Your keyboard should be located in `qmk_firmware/keyboards/` and the folder name should be your keyboard's name as described in the previous section. Inside this folder should be several files:
+
+* `readme.md`
+* `info.json`
+* `config.h`
+* `rules.mk`
+* `<keyboard_name>.c`
+* `<keyboard_name>.h`
+
+### `readme.md`
+
+All projects need to have a `readme.md` file that explains what the keyboard is, who made it and where it's available. If applicable, it should also contain links to more information, such as the maker's website. Please follow the [published template](documentation_templates.md#keyboard-readmemd-template).
+
+### `info.json`
+
+This file is used by the [QMK API](https://github.com/qmk/qmk_api). It contains the information [QMK Configurator](https://config.qmk.fm/) needs to display a representation of your keyboard. You can also set metadata here. For more information see the [reference page](reference_info_json.md).
+
+### `config.h`
+
+All projects need to have a `config.h` file that sets things like the matrix size, product name, USB VID/PID, description and other settings. In general, use this file to set essential information and defaults for your keyboard that will always work.
+
+### `rules.mk`
+
+The presence of this file means that the folder is a keyboard target and can be used in `make` commands. This is where you setup the build environment for your keyboard and configure the default set of features.
+
+### `<keyboard_name.c>`
+
+This is where you will write custom code for your keyboard. Typically you will write code to initialize and interface with the hardware in your keyboard. If your keyboard consists of only a key matrix with no LEDs, speakers, or other auxillary hardware this file can be blank.
+
+The following functions are typically defined in this file:
+
+* `void matrix_init_kb(void)`
+* `void matrix_scan_kb(void)`
+* `bool process_record_kb(uint16_t keycode, keyrecord_t *record)`
+* `void led_set_kb(uint8_t usb_led)`
+
+### `<keyboard_name.h>`
+
+This file is used to define the matrix for your keyboard. You should define at least one C macro which translates an array into a matrix representing the physical switch matrix for your keyboard. If it's possible to build your keyboard with multiple layouts you should define additional macros.
+
+If you have only a single layout you should call this macro `LAYOUT`.
+
+When defining multiple layouts you should have a base layout, named `LAYOUT_all`, that supports all possible switch positions on your matrix, even if that layout is impossible to build physically. This is the macro you should use in your `default` keymap. You should then have additional keymaps named `default_<layout>` that use your other layout macros. This will make it easier for people to use the layouts you define.
+
+Layout macro names are entirely lowercase, except for the word `LAYOUT` at the front.
+
+As an example, if you have a 60% PCB that supports ANSI and ISO you might define the following layouts and keymaps:
+
+| Layout Name | Keymap Name | Description |
+|-------------|-------------|-------------|
+| LAYOUT_all | default | A layout that supports both ISO and ANSI |
+| LAYOUT_ansi | default_ansi | An ANSI layout |
+| LAYOUT_iso | default_iso | An ISO layout |

 As documented on [Customizing Functionality](custom_quantum_functions.md) you can define custom functions for your keyboard. Please keep in mind that your users may want to customize that behavior as well, and make it possible for them to do that. If you are providing a custom function, for example `process_record_kb()`, make sure that your function calls the `_user()` version of the call too. You should also take into account the return value of the `_user()` version, and only run your custom code if the user returns `true`.
 
-## Keyboard Metadata
-
-As QMK grows so does the ecosystem surrounding QMK. To make it easier for projects in that ecosystem to tie into QMK as we make changes we are developing a metadata system to expose information about keyboards in QMK.
-
-You can create `info.json` files at every level under `qmk_firmware/keyboards/<name>` to specify this metadata. These files are combined, with more specific files overriding keys in less specific files. This means you do not need to duplicate your metadata information. For example, `qmk_firmware/keyboards/clueboard/info.json` specifies `manufacturer` and `maintainer`, while `qmk_firmware/keyboards/clueboard/66/info.json` specifies more specific information about Clueboard 66%.
-
-### `info.json` Format
-
-The `info.json` file is a JSON formatted dictionary with the following keys available to be set. You do not have to set all of them, merely the keys that apply to your keyboard.
-
-* `keyboard_name`
-  * A free-form text string describing the keyboard.
-  * Example: `Clueboard 66%`
-* `url`
-  * A URL to the keyboard's product page, [QMK.fm/keyboards](https://qmk.fm/keyboards) page, or other page describing information about the keyboard.
-* `maintainer`
-  * GitHub username of the maintainer, or `qmk` for community maintained boards
-* `width`
-  * Width of the board in Key Units
-* `height`
-  * Height of the board in Key Units
-* `layouts`
-  * Physical Layout representations. See the next section for more detail.
-
-#### Layout Format
-
-Within our `info.json` file the `layouts` portion of the dictionary contains several nested dictionaries. The outer layer consists of QMK layout macros, for example `LAYOUT_ansi` or `LAYOUT_iso`. Within each layout macro are keys for `width`, `height`, and `key_count`, each of which should be self-explanatory.
-
-* `width`
-  * Optional: The width of the layout in Key Units
-* `height`
-  * Optional: The height of the layout in Key Units
-* `key_count`
-  * **Required**: The number of keys in this layout
-* `layout`
-  * A list of Key Dictionaries describing the physical layout. See the next section for more details.
-
-#### Key Dictionary Format
-
-Each Key Dictionary in a layout describes the physical properties of a key. If you are familiar with the Raw Code for <http://keyboard-layout-editor.com> you will find many of the concepts the same. We re-use the same key names and layout choices wherever possible, but unlike keyboard-layout-editor each key is stateless, inheriting no properties from the keys that came before it.
-
-All key positions and rotations are specified in relation to the top-left corner of the keyboard, and the top-left corner of each key.
-
-* `X`
-  * **Required**: The absolute position of the key in the horizontal axis, in Key Units.
-* `Y`
-  * **Required**: The absolute position of the key in the vertical axis, in Key Units.
-* `W`
-  * The width of the key, in Key Units. Ignored if `ks` is provided. Default: `1`
-* `H`
-  * The height of the key, in Key Units. Ignored if `ks` is provided. Default: `1`
-* `R`
-  * How many degrees clockwise to rotate the key.
-* `RX`
-  * The absolute position of the point to rotate the key around in the horizontal axis. Default: `x`
-* `RY`
-  * The absolute position of the point to rotate the key around in the vertical axis. Default: `y`
-* `KS`
-  * Key Shape: define a polygon by providing a list of points, in Key Units.
-  * **Important**: These are relative to the top-left of the key, not absolute.
-  * Example ISO Enter: `[ [0,0], [1.5,0], [1.5,2], [0.25,2], [0.25,1], [0,1], [0,0] ]`
-
-### How is the Metadata Exposed?
-
-This metadata is primarily used in two ways:
-
-* To allow web-based configurators to dynamically generate UI
-* To support the new `make keyboard:keymap:qmk` target, which bundles this metadata up with the firmware to allow QMK Toolbox to be smarter.
-
-Configurator authors can see the [QMK Compiler](https://docs.compile.qmk.fm/api_docs.html) docs for more information on using the JSON API.
-
 ## Non-Production/Handwired Projects
 
 We're happy to accept any project that uses QMK, including prototypes and handwired ones, but we have a separate `/keyboards/handwired/` folder for them, so the main `/keyboards/` folder doesn't get overcrowded. If a prototype project becomes a production project at some point in the future, we'd be happy to move it to the main `/keyboards/` folder!

-### Custom Functions
-
-At the bottom of the file we've defined a single custom function. This function defines a key that sends `KC_ESC` when pressed without modifiers and `KC_GRAVE` when modifiers are held. There are a couple pieces that need to be in place for this to work, and we will go over both of them.
-
-#### `fn_actions[]`
-
-We define the `fn_actions[]` array to point to custom functions. `F(N)` in a keymap will call element N of that array. For the Clueboard's that looks like this:
-
-    const uint16_t PROGMEM fn_actions[] = {
-      [0] = ACTION_FUNCTION(0),  // Calls action_function()
-    };
-
-In this case we've instructed QMK to call the `ACTION_FUNCTION` callback, which we will define in the next section.
-
-> This `fn_actions[]` interface is mostly for backward compatibility.  In QMK, you don't need to use `fn_actions[]`.  You can directly use `ACTION_FUNCTION(N)` or any other action code value itself normally generated by the macro in `keymaps[][MATRIX_ROWS][MATRIX_COLS]`.  N in `F(N)` can only be 0 to 31.  Use of the action code directly in `keymaps` unlocks this limitation.
-
-You can get a full list of Action Functions in [action_code.h](https://github.com/qmk/qmk_firmware/blob/master/tmk_core/common/action_code.h). 
-
-#### `action_function()`
-
-To actually handle the keypress event we define an `action_function()`. This function will be called when the key is pressed, and then again when the key is released. We have to handle both situations within our code, as well as determining whether to send/release `KC_ESC` or `KC_GRAVE`.
-
-    void action_function(keyrecord_t *record, uint8_t id, uint8_t opt) {
-      static uint8_t mods_pressed;
-
-      switch (id) {
-        case 0:
-          /* Handle the combined Grave/Esc key

+# QMK Configurator
+
+The [QMK Configurator](https://config.qmk.fm) is an online graphical user interface that generates QMK Firmware hex files.  
+
+?> **Please follow these steps in order.**
+
+Watch the [Video Tutorial](https://youtu.be/7RH-1pAbjvw)
+
+The QMK Configurator works best with Chrome/Firefox. 
+
+
+!> **Files from other tools such as KLE, or kbfirmware will not be compatible with QMK Configurator. Do not load them, do not import them. QMK Configurator is a DIFFERENT tool. **
+
+## Selecting 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. 
+
+## Selecting 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. 
+
+## Keymap Name
+
+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.
+
+## Creating Your Keymap
+
+Keycode Entry is accomplished in 3 ways.  
+1. Drag and dropping 
+2. Clicking on an empty spot on the layout and clicking the keycode you desire
+3. Clicking on an empty spot on the layout, 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](https://docs.qmk.fm/#/keycodes_basic)    
+[Advanced Keycode Reference](https://docs.qmk.fm/#/feature_advanced_keycodes)    
+
+In the event that you can't find a layout that supports your keymap, for example three spots for spacebar, or two spots for backspace, or 2 spots for shift etc etc, Fill them ALL up. 
+
+### Example:
+
+3 spots for spacebar: Fill them ALL with spacebar
+
+2 spots for backspace: Fill them BOTH with backspace
+
+2 spots for right shift: Fill them BOTH with right shift
+
+1 spot for left shift and 1 spot for iso support: Fill them both with left shift
+
+5 spots, but only 4 keys: Guess and check or ask someone who has done it before. 
+
+## Saving Your Keymap for Future Edits
+
+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 as the name you chose above appended with .json. 
+
+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, there is a chance your keyboard will **explode**. 
+
+## Generating your firmware file
+
+Press the green `Compile` button.
+
+When the compilation is done, you will be able to press the green `Download Firmware` button. 
+
+## Flashing Your Keyboard
+
+Please refer to [Flashing Firmware](newbs_flashing.md)
+
+## Troubleshooting
+
+#### My .json file is not working
+
+If the .json file was generated with QMK Configurator, congratulations you have stumbled upon a bug. File an issue at [qmk_configurator](https://github.com/qmk/qmk_configurator/issues)
+
+If not....how did you miss my 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 bar. The same can be done for backspace and shifts
+
+#### What is the keycode for.......
+
+Please see
+
+[Basic Keycode Reference](https://docs.qmk.fm/#/keycodes_basic)    
+[Advanced Keycode Reference](https://docs.qmk.fm/#/feature_advanced_keycodes)    
+
+#### It won't compile
+
+Please double check the other layers of your keymap to make sure there are no random keys present.

+# Setting up Visual Studio Code for QMK Development
+
+[Visual Studio Code](https://code.visualstudio.com/) (VS Code) is an open-source code editor that supports many different programming languages. 
+
+Using a full-featured editor such as VS Code provides many advantages over a plain text editor, such as:
+* intelligent code completion
+* convenient navigation in the code
+* refactoring tools
+* build automation (no need for the command-line)
+* a graphical front end for GIT
+* many other tools such as debugging, code formatting, showing call hierarchies etc.
+
+The purpose of this page is to document how to set up VS Code for developing QMK Firmware.
+
+This guide covers how to configure everything needed on Windows and Ubuntu 18.04
+
+# Set up VS Code
+Before starting, you will want to make sure that you have all of the build tools set up, and QMK Firmware cloned. Head to the the [Newbs Getting Started Guide](newbs_getting_started.md) to get things set up, if you haven't already.
+
+## Windows
+
+### Prerequisites
+
+* [Git for Windows](https://git-scm.com/download/win) (This link will prompt to save/run the installer)
+  
+  1. Disable all of the options but `Git LFS (Large File Support)` and `Check daily for Git for Windows updates`. 
+  2. Set the default editor to `Use Visual Studio Code as Git's default editor`
+  3. Select the `Use Git from Git Bash only` option, since that's the option that you should use here.
+  4. For the `Choosing HTTPS transport backend`, either option should be fine.
+  5. Select the `Checkout as-is, commit Unix-style line endings` option. QMK Firmware uses Unix style commits.
+  6. For the extra options, leave the default options as is. 
+
+  This software is needed for Git support in VS Code. It may be possible to not include this, but it is much simpler to just use this. 
+
+* [Git Credential Manager for Windows](https://github.com/Microsoft/Git-Credential-Manager-for-Windows/releases) (Optional) 
+
+  This software provides better support for Git by providing secure storage for git credentials, MFA and personal access token generation. 
+  
+  This isn't strictly needed, but we would recommend it. 
+
+
+### Installing VS Code
+
+1. Head to [VS Code](https://code.visualstudio.com/) and download the installer
+2. Run the installer
+
+This part is super simple.  However, there is some configuration that we need to do to ensure things are configured correctly.
+
+### Configuring VS Code
+
+First, we need to set up IntelliSense. This isn't strictly required, but it will make your life a LOT easier. To do this, we need to create the `.vscode/c_cpp_properies.json` file in the QMK Firmware folder, You can do this all manually, but I've done most of the work already. 
+
+Grab [this file](https://gist.github.com/drashna/48e2c49ce877be592a1650f91f8473e8) and save it.  You may need to edit this file, if you didn't install MSYS2 to the default location, or are using WSL/LxSS.  
+
+Once you have saved this file, you will need to reload VS Code, if it was already running. 
+
+?> You should see an `extensions.json` and `settings.json` file in the `.vscode` folder, as well.
+
+
+Now, we will set up the MSYS2 window to show up in VSCode as the integrated terminal.  This has a number of advantages. Mostly, you can control+click on errors and jump to those files.  This makes debugging much easier.  It's also nice, in that you don't have to jump to another window. 
+
+1. Click <kbd><kbd>File</kbd> > <kbd>Preferences ></kbd> > <kbd>Settings</kbd> </kbd>
+2. Click on the <kbd>{}</kbd> button, in the top right to open the `settings.json` file. 
+3. Set the file's content to: 
+
+   ```json
+   {
+        "terminal.integrated.shell.windows": "C:\\msys64\\usr\\bin\\bash.exe",
+        "terminal.integrated.env.windows": {
+            "MSYSTEM": "MINGW64",
+            "CHERE_INVOKING": "1"
+        },
+        "terminal.integrated.shellArgs.windows": [
+            "--login"
+        ],
+        "terminal.integrated.cursorStyle": "line"
+    }
+    ```
+
+   If there are settings here already, then just add everything between the first and last curly brackets.  
+
+?> If you installed MSYS2 to a different folder, then you'll need to change the path for `terminal.integrated.shell.windows` to the correct path for your system. 
+
+4. Hit Ctrl-` (grave) to bring up the terminal.  
+
+   This should start the terminal in the workspace's folder (so the `qmk_firmware` folder), and then you can compile your keyboard. 
+
+
+## Every other Operating System
+
+1. Head to [VS Code](https://code.visualstudio.com/) and download the installer
+2. Run the installer
+3. That's it
+
+No, really, that's it.  The paths needed are already included when installing the packages, and it is much better about detecting the current workspace files and parsing them for IntelliSense. 
+
+## Plugins
+
+There are a number of extensions that you may want to install:
+
+* [Git Extension Pack](https://marketplace.visualstudio.com/items?itemName=donjayamanne.git-extension-pack) - 
+This installs a bunch of Git related tools that may make using Git with QMK Firmware easier.
+* [EditorConfig for VS Code](https://marketplace.visualstudio.com/items?itemName=EditorConfig.EditorConfig) - _[Optional]_ -  Helps to keep the code to the QMK Coding Conventions.
+* [Bracket Pair Colorizer 2](https://marketplace.visualstudio.com/items?itemName=CoenraadS.bracket-pair-colorizer-2) - _[Optional]_ - This color codes the brackets in your code, to make it easier to reference nested code.
+* [Github Markdown Preview](https://marketplace.visualstudio.com/items?itemName=bierner.github-markdown-preview) - _[Optional]_ - Makes the markdown preview in VS Code more like GitHub's.
+* [VS Live Share Extension Pack](https://marketplace.visualstudio.com/items?itemName=MS-vsliveshare.vsliveshare-pack) - _[Optional]_ - This extension allows somebody else to access your workspace (or you to access somebody else's workspace) and help out.  This is great if you're having issues and need some help from somebody.
+* [VIM Keymap](https://marketplace.visualstudio.com/items?itemName=GiuseppeCesarano.vim-keymap) - _[Optional]_ - For those that prefer VIM style keybindings. There are other options for this, too. 
+* [Travis CI Status](https://marketplace.visualstudio.com/items?itemName=felixrieseberg.vsc-travis-ci-status) - _[Optional]_ - This shows the current Travis CI status, if you have it set up.
+
+Restart once you've installed any extensions
+
+# Configure VS Code for QMK

+# Converting a board to use the Proton C
+
+If a board currently supported in QMK uses a Pro Micro (or compatible board) and you want to use the Proton C, you can generate the firmware by appending `CONVERT_TO_PROTON_C=yes` (or `CTPC=yes`) to your make argument, like this:
+
+    make 40percentclub/mf68:default CTPC=yes
+
+You can add the same argument to your keymap's `rules.mk`, which will accomplish the same thing.
+
+This exposes the `CONVERT_TO_PROTON_C` flag that you can use in your code with `#ifdef`s, like this:
+
+    #ifdef CONVERT_TO_PROTON_C
+        // Proton C code
+    #else
+        // Pro Micro code
+    #endif
+
+Before being able to compile, you may get some errors about `PORTB/DDRB`, etc not being defined, so you'll need to convert the keyboard's code to use the [GPIO Controls](internals_gpio_control.md) that will work for both ARM and AVR. This shouldn't affect the AVR builds at all.
+
+The Proton C only has one on-board LED (C13), and by default, the TXLED (D5) is mapped to it. If you want the RXLED (B0) mapped to it instead, add this like to your `config.h`:
+
+    #define CONVERT_TO_PROTON_C_RXLED

+
+This page covers how to properly support keyboards in the [QMK Configurator](https://config.qmk.fm/).
+
+
+## How the Configurator Understands Keyboards
+
+To understand how the Configurator understands keyboards, first one must understand layout macros. For this exercise, we're going to imagine a 17-key numpad PCB, which we're going to call `numpad`.
+
+```
+┌───┬───┬───┬───┐
+│NLk│ / │ * │ - │
+├───┼───┼───┼───┤

+```
+
+?> For more on layout macros, see [Understanding QMK: Matrix Scanning](understanding_qmk.md?id=matrix-scanning) and [Understanding QMK: Matrix to Physical Layout Map](understanding_qmk.md?id=matrix-to-physical-layout-map).
+
+The Configurator's API reads the keyboard's `.h` file from `qmk_firmware/keyboards/<keyboard>/<keyboard>.h`. For our numpad, this file would be `qmk_firmware/keyboards/numpad/numpad.h`:
+
+```c
+#pragma once
+
+#define LAYOUT( \
+    k00, k01, k02, k03, \
+    k10, k11, k12, k13, \
+    k20, k21, k22,      \
+    k30, k31, k32, k33, \
+    k40,      k42       \
+  ) { \
+    { k00, k01,   k02, k03   }, \
+    { k10, k11,   k12, k13   }, \
+    { k20, k21,   k22, KC_NO }, \
+    { k30, k31,   k32, k33   }, \
+    { k40, KC_NO, k42, KC_NO }  \
+}
+```
+
+QMK uses `KC_NO` to designate places in the switch matrix where there is no switch. Sometimes, `XXX`, `___` or `____` are used as shorthand to make this section easier to read if it needs to be debugged. This is usually defined near the beginning of the `.h` file:
+
+```c
+#pragma once
+
+#define XXX KC_NO
+
+#define LAYOUT( \
+    k00, k01, k02, k03, \
+    k10, k11, k12, k13, \
+    k20, k21, k22,      \
+    k30, k31, k32, k33, \
+    k40,      k42       \
+  ) { \
+    { k00, k01, k02, k03 }, \
+    { k10, k11, k12, k13 }, \
+    { k20, k21, k22, XXX }, \
+    { k30, k31, k32, k33 }, \
+    { k40, XXX, k42, XXX }  \
+}
+```
+
+!> This usage differs from that of keymap macros, which almost always use `XXXXXXX` (seven capital X's) for `KC_NO` and `_______` (seven underscores) for `KC_TRNS`.
+
+!> To prevent user confusion, using `KC_NO` is preferred.
+
+The layout macro tells the Configurator that our keyboard has 17 keys, arranged in five rows of four columns each. Our switch positions are named `k<row><column>`, counting from 0. The names themselves actually don't matter, as long as they match between the top section, which receives the keycodes from the keymap, and the bottom half which designates where each key is in the matrix.
+
+To display our keyboard in a way that resembles the physical keyboard, we need to build a JSON file that tells the Configurator how to tie the physical locations and sizes of our keys to our switch matrix.
+
+## Building the JSON file
+
+To build the JSON file, the easiest way is to build the layout in [Keyboard Layout Editor](http://www.keyboard-layout-editor.com/) ("KLE"), from which we'll feed the Raw Data into a QMK tool that converts this data into a JSON the Configurator will read and use. Since KLE opens by default with a numpad layout, we're just going to remove the Getting Started instructions, and use what's left.
+
+Once the layout is as desired, move to the Raw Data tab in KLE, and copy the contents:
+
+```
+["Num Lock","/","*","-"],
+["7\nHome","8\n↑","9\nPgUp",{h:2},"+"],
+["4\n←","5","6\n→"],
+["1\nEnd","2\n↓","3\nPgDn",{h:2},"Enter"],
+[{w:2},"0\nIns",".\nDel"]
+```
+
+To convert this data into our JSON, go to the [QMK KLE-JSON Converter](https://qmk.fm/converter/), paste the Raw Data into the Input field, and click the Convert button. After a moment, our JSON data will appear in the Output field. Copy the contents to a new text document, and name the document `info.json`, saving it in the same folder that contains `numpad.h`.
+
+Use the `keyboard_name` object to set the name of the keyboard. The `bootloader` object is deprecated, so it can be deleted. For instruction purposes, we will put each key's object on its own line. This is only to make the file more human-readable, and does not affect the Configurator's functionality.
+

+            ]
+        }
+    }
+}
+```
+
+The `layouts` object contains the data that represents the physical layout of the keyboard. It has an object `LAYOUT`, which needs to match the name of our layout macro from `numpad.h`. The `LAYOUT` object itself has an object named `layout`, which contains one JSON object for each physical key on our keyboard, formatted as follows:
+
+```
+  ┌ The name of the key. Not displayed in the Configurator.
+  │                   ┌ The key's X-axis location, in key units from the
+  │                   │ keyboard's left edge.
+  │                   │      ┌ The key's Y-axis location, in key units from
+  │                   │      │ the keyboard's top (rear-facing) edge.
+  ↓                   ↓      ↓
+{"label":"Num Lock", "x":0, "y":0},
+```
+
+Some objects will also have `"w"` and `"h"` keys, which represent a key's width and height, respectively.

+When a user selects the top-left key in the Configurator, and assigns Num Lock to it, the Configurator builds a keymap file with `KC_NLCK` as the first key, and so on as the keymap is built. The `label` keys are not used; they are only for the user's reference in identifying specific keys when debugging the `info.json` file.
+
+
+## Issues and Hazards
+
+Currently, the Configurator does not support key rotation or non-rectangular key shapes like ISO Enter. Additionally, keys that are vertically-offset from their "row" &mdash; the arrow keys on 1800-layouts like the [TKC1800](https://github.com/qmk/qmk_firmware/tree/4ac48a61a66206beaf2fdd5f2939d8bbedd0004c/keyboards/tkc1800/) being a prominent example &mdash; confuse the KLE-to-JSON Converter, if not adjusted for by the contributor of the `info.json` file.
+
+### Workarounds
+
+#### Non-rectangular keys
+
+For ISO Enter keys, QMK custom is to display it as a rectangular key, 1.25u wide and 2u high, aligned so its right edge is aligned with the right edge of the alphanumeric key block.

+#### Vertically-offset keys

+# `info.json`
+
+This file is used by the [QMK API](https://github.com/qmk/qmk_api). It contains the information [QMK Configurator](https://config.qmk.fm/) needs to display a representation of your keyboard. You can also set metadata here.
+
+You can create `info.json` files at every level under `qmk_firmware/keyboards/<name>` to specify this metadata. These files are combined, with more specific files overriding keys in less specific files. This means you do not need to duplicate your metadata information. For example, `qmk_firmware/keyboards/clueboard/info.json` specifies `manufacturer` and `maintainer`, while `qmk_firmware/keyboards/clueboard/66/info.json` specifies more specific information about Clueboard 66%.
+
+## `info.json` Format
+
+The `info.json` file is a JSON formatted dictionary with the following keys available to be set. You do not have to set all of them, merely the keys that apply to your keyboard.
+
+* `keyboard_name`
+  * A free-form text string describing the keyboard.
+  * Example: `Clueboard 66%`
+* `url`
+  * A URL to the keyboard's product page, [QMK.fm/keyboards](https://qmk.fm/keyboards) page, or other page describing information about the keyboard.
+* `maintainer`
+  * GitHub username of the maintainer, or `qmk` for community maintained boards
+* `width`
+  * Width of the board in Key Units
+* `height`
+  * Height of the board in Key Units
+* `layouts`
+  * Physical Layout representations. See the next section for more detail.
+
+### Layout Format
+
+Within our `info.json` file the `layouts` portion of the dictionary contains several nested dictionaries. The outer layer consists of QMK layout macros, for example `LAYOUT_ansi` or `LAYOUT_iso`. Within each layout macro are keys for `width`, `height`, and `key_count`, each of which should be self-explanatory.
+
+* `width`
+  * Optional: The width of the layout in Key Units
+* `height`
+  * Optional: The height of the layout in Key Units
+* `key_count`
+  * **Required**: The number of keys in this layout
+* `layout`
+  * A list of Key Dictionaries describing the physical layout. See the next section for more details.
+
+### Key Dictionary Format
+
+Each Key Dictionary in a layout describes the physical properties of a key. If you are familiar with the Raw Code for <http://keyboard-layout-editor.com> you will find many of the concepts the same. We re-use the same key names and layout choices wherever possible, but unlike keyboard-layout-editor each key is stateless, inheriting no properties from the keys that came before it.
+
+All key positions and rotations are specified in relation to the top-left corner of the keyboard, and the top-left corner of each key.
+
+* `x`
+  * **Required**: The absolute position of the key in the horizontal axis, in Key Units.
+* `y`
+  * **Required**: The absolute position of the key in the vertical axis, in Key Units.
+* `w`
+  * The width of the key, in Key Units. Ignored if `ks` is provided. Default: `1`
+* `h`
+  * The height of the key, in Key Units. Ignored if `ks` is provided. Default: `1`
+* `r`
+  * How many degrees clockwise to rotate the key.
+* `rx`
+  * The absolute position of the point to rotate the key around in the horizontal axis. Default: `x`
+* `ry`
+  * The absolute position of the point to rotate the key around in the vertical axis. Default: `y`
+* `ks`
+  * Key Shape: define a polygon by providing a list of points, in Key Units.
+  * **Important**: These are relative to the top-left of the key, not absolute.
+  * Example ISO Enter: `[ [0,0], [1.5,0], [1.5,2], [0.25,2], [0.25,1], [0,1], [0,0] ]`
+* `label`
+  * What to name this position in the matrix.
+  * This should usually be the same name as what is silkscreened on the PCB at this location.
+
+## How is the Metadata Exposed?
+
+This metadata is primarily used in two ways:
+
+* To allow web-based configurators to dynamically generate UI
+* To support the new `make keyboard:keymap:qmk` target, which bundles this metadata up with the firmware to allow QMK Toolbox to be smarter.
+
+Configurator authors can see the [QMK Compiler](https://docs.api.qmk.fm/using-the-api) docs for more information on using the JSON API.

+
+## 什麼是QMK固件？
+
+QMK是一個由社群維護的開源鍵盤韌體，其中包含了QMK Toolbox、qmk.fm和其它文件。QMK韌體是以[tmk\_keyboard](http://github.com/tmk/tmk_keyboard)為基礎，讓一些有用的功能在Atmel AVR控制器實現，使用於[OLKB](https://olkb.com)、[ergodox EZ](http://www.ergodox-ez.com)，和[Clueboard](http://clueboard.co/)的產品中。它也被移植到使用ChibiOS的ARM晶片上。你也可以用它來讓你徒手佈線，或是客製的鍵盤PCB發揮功能。
+
+## 如何得到QMK
+
+如果你打算貢獻鍵盤佈局，鍵盤或功能QMK，最容易做的事情是[叉通過Github上爬行](https://github.com/qmk/qmk_firmware#fork-destination-box)，和克隆你爬在本地進行更改，推動他們，然後打開從你的叉子[拉請求](https://github.com/qmk/qmk_firmware/pulls)。
+
+否則，您可以直接下載([拉鍊](https://github.com/qmk/qmk_firmware/zipball/master) [焦油](https://github.com/qmk/qmk_firmware/tarball/master))，或者通過GIT中克隆它(`git@github.com:qmk/qmk_firmware.git`)或HTTP(`https://github.com/qmk/qmk_firmware.git`)。
+
+## 如何編譯
+
+你可以編譯之前，你需要[安裝環境](getting_started_build_tools.md)用於AVR或/和ARM開發。一旦完成，你會使用`make`命令建立一個鍵盤並用以下符號鍵盤佈局
+
+    make planck/rev4:default
+
+這將建立`rev4` `planck`的修訂與`default`鍵盤映射。並非所有鍵盤有一個修訂版(也稱為子項目或文件夾)，在這種情況下，它可以被省略：
+
+    make preonic:default
+
+## 如何赶近
+
+QMK有很多[特點](features.md)探索和很好的協議[參考文獻](http://docs.qmk.fm)挖通的。大部分功能通過修改[鍵盤映射(keymap.md)，並改變[鍵碼](keycodes.md)冤大頭。
