-Buswerks' 4x12 Ortholinear Layout
-============================
-For use on Planck, Let's Split, and similar keyboards

-### Layout Overview
+# Logan's Ortho 4x12 Layout
 
-- Main Layer
-	- Enter is located on the Raise key (layer-tap)
-	- Space Cadet shift keys
-		- Lower + shift keys = Brackets[]
-		- Raise + shift keys = Braces{}
-	- The bottom left key is the Adjust modifier
-	- Escape is in the traditional Caps Lock position
-		- Holding down the escape key acts as LGUI (intended for macOS use)
-- Lower
-	- There is a numpad on the right hand (4, 5, and 6 are located under JKL/NEI/HTN)
-	- Plus and minus keys are located to the right of the numpad
-	- There are macOS desktop navigation keys and volume controls under the left hand
+This layout is what I use on my Planck. Some features of the layout:
 
-- Raise
-	- Vim-style arrow keys
-		- Below the arrow keys are home, end, pgup, and pgdn
-	- Symbols are located on the right side of the keyboard, in a somewhat logical order
-		- Symbols from the number row are in order, starting on the left pinky.
-		- Equals and underscore are in easily accessible spots, since they're commonly used in programming
-		- The ampersand is less common, so it's to the right of the equals symbol
-		
-- Adjust
-	- Function keys are located along the top row (reset is moved to the Colemak 'R' position)
+- Rotary encoder support (no function for clicking yet)
+- Numpad under right hand (I find this much more comfortable than touch-typing the number row)
+- Space cadet shift
+- Curly braces are under the home row (makes programming much more comfortable)
+
+Also, another note: the QWERTY layout uses `LGUI_T(KC_ESC)` and the COLEMAK/DVORAK layouts use `LCTL_T(KC_ESC)`. This is because I use the QWERTY layout on my Mac laptop so that I don't have to change the software remapping every time I dock my laptop. This also allows a convenient remapping of the modifier keys. I use the hardware mapped COLEMAK layout on Linux.
