-This is a collection of my most commonly used QMK functions
+This is a collection of my most commonly used QMK features. 
+
+A majority of my keyboards are smaller than 75%, ANSI, and staggered. 
+
+## Layers
+----
+
+### _BL (Base Layer)
+Typical standard QWERTY keymap.
+
+### _FL (Function Layer)
+This layer is commonly accessed via `MO(_FL)` on the base layer. It consists of your typical function key F1 through F12 and some RGB and Backlight controls. 
+
+### _AL (Arrow Layer)
+This layer is only present on my 60% boards. I habitually use the bottom right modifiers as arrows. 
+
+### _CL (Control Layer)
+This is not defined in here as it's present only on `LAYOUT_66` boards, or to be specific, my clueboard. It currently uses the default clueboard controls.
+
+## Custom Keycodes
+----
+
+### KC_FNX (Fn Extended)
+
+`KC_FNX` functions as a hold for `MO(X)` and tap for `TG(Y)`. Layer X and Y are different layers. 
+
+It is used primarily on my `LAYOUT_60_ansi` boards as my regular toggle (the 1u key to the right of right shift), is not present there. 
+
+### KC_CTCP (Control Caps)
+
+This is just a wrapper for `CTL_T(KC_CAPS)`. This is a hold for control and tap for caps lock. 
+
+## QMK Features
+----
+
+### RGBLIGHT_SLEEP
+
+Ensures that when my computer is in sleep mode, the keyboard underglow lights will also be off.
