+# Default Unicorne Layout
+
+This is the default layout for Unicorne. The "lower" layer consists of symbols
+and navigation, while "raises' has numbers, some other symbols and function
+keys.
+
+Press `lower` and `raise` together activates `adjust` layer, with RGB controls,
+as well as access to reset/bootloader.
