+# bcat's 60% Tsangan HHKB layout
+
+This is a normal Tsangan/HHKB (split backspace, split right shift) layout with
+arrow and navigation keys that match a standard HHKB layout, as well as media
+keys centered around the WASD cluster. Additionally, the redundant right Super
+key on the bottom row actives an adjust layer to control RGB underglow.
