-# KidBrazil's custom CRKBD Layout
-
-![Loose Transistor Crkbd](https://user-images.githubusercontent.com/4823043/71268460-0862c000-231b-11ea-8f32-2fe8da4d348a.jpg)
-
-This is a simple layout that I use for both programming and gaming. It is very
-closely based on the original CRKBD layout with some modifications to the
-position of CTRL and SHIFT.
-
-## Layers
-This keymap includes a total of 4 Layers:
-- QWERTY
-- NUMBERS
-- SYMBOLS
-- GAMING
-- WEAPONS
-
-The first three layers are pretty self explanatory and follow closely the
-default keymap for this keyboard. The magic really starts to happen with the
-gaming layer.
-
-### Gaming Layer
-The gaming layer can be toggled on/off from the SYMBOLS layer. Once on the
-gaming layer it will stay there until you toggle it off again. The gaming layer
-includes normal WASD and most of the keys FPS games use on the left hand. On the
-right hand we have F1-F12 and a few other special keys for games that require
-it.
-
-### Weapon
-The weapon layer is a momentary layer that can only be reached from the gaming
-layer. This layer preserves the left hand almost unchanged, except for when the
-layer is activated the top row becomes NUM 1 - 6 for wepon selection. The right
-hand is KC_TRNS the whole way so basically it is still the gaming layer.
-
-## Custom Font
-This keymap includes a custom font for my LooseTransistor logo. It is fine if
-you want to use it I certainly don't mind but if you want your own, just replace
-the glcdfont file here and you should be fine.
-
-Alternatively you could remove the font config line from the config.h file so it
-will use the default QMK one.
-
-## OLED
-This Keymap is setup to use the newer OLED API. Some work has been done to
-customize this with showing layer and USB information. I also tried my best to
-get a dormant / sleep state going but it is hit or miss and often only works on
-the master hand.
-
-## OLED & RGB Matrix timeout
-This keymap will set a automated timeout system for the OLED screen and the RGB
-matrix. After 3 minutes or so the LED screen will display the logo on both
-halves and 5 minutes after that both the LED and the Matrix will be switched
-off.
-
-Once a user hits the keys again, the LED matrix will turn back on unless the
-user has disabled it via RGB_TOG.
-
-## Flashing
-To flash this on your CRKBD simply use the `make crkbd:kidbrazil:flash`
-command.
-
-### TODO
-- Wait for Spit_common to be implemented in CRKBD and revisit the special color
-  layers and animations
