+# Xton has a tiny keyboard! With Vim!
+
+Based on the standard Planck layout with a few changes:
+
+* Escape moved to dual-function with control.
+* Dedicated movement and mouse layers.
+* Top and middle row swapped in `_RAISE` and `_LOWER` because I never use F-keys.
+* Vim layers! See `users/xtonhasvim`.
