+# heatxsink's keymap for kinesis advantage w/ kinx
+
+## my keymap has three objectives ...
+1. Make it easy to add keyboard layouts (layers).
+2. Easy to swap between keyboard layouts (layers).
+3. Use LED indicators on the kinX controller to provide feedback as to what layer is selected.
+
+## layer description
+0. DEFAULT (function key row, number row, left/right gutter keys, and thumb keys)
+1. QWERTY
+2. CMMDH [Colemak Mod-DH](https://colemakmods.github.io/mod-dh/)
+3. WM [Workman](https://workmanlayout.org/)
+3. Keypad (number pad on the right, media keys on the left)
+
+## layers
+```
+Keymap: DEFAULT
+Description: keys separated by "/" tap for first, hold for second; uses Space Cadet Shifts
