+# Default Layer #
+
+I'm using the colemak layer -- customized a bit to work a bit better when using spacemacs as my editor.
+
+![default-layer](https://i.imgur.com/7uRqlWw.png)
+
+## Special Keys ##
+
+`SC1` => `LGUI + TAB`
+
+`SC2` => `LGUI + SPACE + TAB`
+
+`L1` => Switch to QWERTY Layout
+
+`T(L2)` => Toggle Symbol Layer
+
+`T(L3)` =>  Toggle Number and D-Pad Layer
+
+# QWERTY #
+
+Nothing special here -- just need this layer tucked away for the `WASD`.  Which is literally the only reason I use it.
+Just have the same button to toggle back to colemak.
+
+# Symbol Layer #
+
+![symbol-layer](https://i.imgur.com/ppT0rIU.png)
+
+This is just putting matching closing symbols next to each other -- useful when editing lisp.
+
+# Number and D-Pad Layer #
+
+Just a basic number layer with a D-PAD on the other side.
