+# bcat's Unicorne layout
+
+This ergo layout follows my preferred [split 3x6 + 3 thumb
+keys](https://github.com/qmk/qmk_firmware/tree/master/layouts/community/split_3x6_3/bcat)
+layout, adding bindings for the two rotary encoders on the bottom row. (The
+left encoder scrolls vertically and the right encoder adjusts volume.) Also,
+since the Unicorne keyboard has a speaker, I added bindings on the adjust layer
+to activate and configure music mode. Finally, an adorable unicorn prances on
+the OLED, running faster the quicker you type.
