+## Configuring the Behavior of Mousekeys with 3-speed constant movement
+
+In your keymap's `config.h`, you must add the line:
+```
+#define MK_3_SPEED
+```
+Then you can precisely define 3 different speeds for both the cursor and the mouse wheel, and also whether speed selection is momentary or tap-to-select.
+For each speed, you can specify how many milliseconds you want between reports(interval), and how far you want to it to move per report(offset).
+
+For example:
+
+```
+#define MK_3_SPEED
+#define MK_MOMENTARY_ACCEL // comment this out for tap-to-select acceleration
+// cursor speeds:
+#define MK_C_OFFSET_SLOW     1 // pixels
+#define MK_C_INTERVAL_SLOW 100 // milliseconds
+#define MK_C_OFFSET_MED      4
+#define MK_C_INTERVAL_MED   16
+#define MK_C_OFFSET_FAST    12
+#define MK_C_INTERVAL_FAST  16
+// scroll wheel speeds:
+#define MK_W_OFFSET_SLOW     1 // wheel clicks
+#define MK_W_INTERVAL_SLOW 400 // milliseconds
+#define MK_W_OFFSET_MED      1
+#define MK_W_INTERVAL_MED  200
+#define MK_W_OFFSET_FAST     1
+#define MK_W_INTERVAL_FAST 100
+```
+
+Medium values will be used as the default or unmodified speed.
+The speed at which both the cursor and scrolling move can be selected with KC_ACL0, KC_ACL1, KC_ACL2 for slow, medium, and fast. However, if you leave MK_MOMENTARY_ACCEL defined then there is no need to ever send KC_ACL1, since that will be the unmodified speed.

+It's a Taco with a side of HASL. A 12 key fiesta of a board.
+
+Keyboard Maintainer: [Jeremy Bernhardt](https://github.com/germ)  
+Hardware Supported: ErgoTaco  
+Hardware Availability: [gboards.ca](http://gboards.ca)  
+
+## Firmware building
+Clone the QMK Repo and install dfu-programmer, flash with:
+
+    make ergotaco:default:dfu
+
+And reset your keyboard!
+
+To just test if your build system is sane, try compiling the default keymap using:
+   
+    make ergotaco:default
+
+See the [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) and the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information. Brand new to QMK? Start with our [Complete Newbs Guide](https://docs.qmk.fm/#/newbs).

+# E6-V2 Bootmapper Client (ps2avrgb)
+
+These docs are for the BMC version of the E6-V2 PCB which has an atmega32a microcontroller. Please do not flash this `.hex` file on your atmega32u4 equipped E6-V2. 
+
+Keyboard Maintainer: [MechMerlin](https://github.com/mechmerlin)  
+Hardware Supported: ps2avrgb E6-V2 with atmega32a microcontroller  
+Hardware Availability: [geekhack.org/index.php?topic=90787.0](https://geekhack.org/index.php?topic=90787.0)  
+
+Make example for this keyboard (after setting up your build environment):
+
+    make exclusive/e6v2/bmc:default
+
+Flashing
+
+ps2avr(GB) boards use an atmega32a microcontroller and a different bootloader. It is not flashable using the regular QMK methods. 
+
+**Reset Key:**  Hold down the key located at `K00`, commonly programmed as left control while plugging in the keyboard. You may also hold down the key located at `K50`, commonly programmed as the escape key. 
+
+Windows: 
+1. Download [HIDBootFlash](http://vusb.wikidot.com/project:hidbootflash).
+2. Place your keyboard into reset. 
+3. Press the `Find Device` button and ensure that your keyboard is found.
+4. Press the `Open .hex File` button and locate the `.hex` file you created.
+5. Press the `Flash Device` button and wait for the process to complete. 
+
+macOS:
+1. Install homebrew by typing the following:   
+    ```
+    /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
+    ```
+2. Install `crosspack-avr`.  
+    ```
+    brew cask install crosspack-avr
+    ```
+3. Install the following packages:
+    ```
+    brew install python
+    pip3 install pyusb
+    brew install --HEAD`https://raw.githubusercontent.com/robertgzr/homebrew-tap/master/bootloadhid.rb
+
+4. Place your keyboard into reset. 
+5. Flash the board by typing `bootloadHID -r` followed by the path to your `.hex` file. 
+
+See the [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) and the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information. Brand new to QMK? Start with our [Complete Newbs Guide](https://docs.qmk.fm/#/newbs).

+driver. It configures V-USB for USB D+ connected to Port D bit 2 (which is
+also hardware interrupt 0 on many devices) and USB D- to Port D bit 4. You may
+wire the lines to any other port, as long as D+ is also wired to INT0 (or any
+other hardware interrupt, as long as it is the highest level interrupt, see
+section at the end of this file).

+ * Descriptor properties are or-ed or added together, e.g.:
+ * #define USB_CFG_DESCR_PROPS_DEVICE   (USB_PROP_IS_RAM | USB_PROP_LENGTH(18))

+It is an approximation of a 60% layout with the alternate layers set up for programming,
+with brackets and parenthesis on the homerow
+Other things I changed were swapping around delete, backspace, and capslock around
+It also uses layer based rgb underglow, and the underglow flashes when capslock is enabled

+# msiu's keymap for katana: standard QWERTY layout with planck like layers
+
+This layout take a standard QWERTY default layer, with raise and lower layers similar to planck. It is for me to easily transition between keyboards. I put a few nav keys in the 'tree' middle, but I have come to realise I rarely use them as I am used to the planck layering. Top of the tree is a toggle for Dvorak layer.
