+The keys here are labeled as per Qwerty, with L1, L2, L3, R3, R2, and R1 for the thumbs.
+
+The firmware follows the `LAYOUT_split_3x5_3` QMK community layout convention, making it much
+easier to use with an existing layout like Miryoku.
 
 The first physical PCB for this was designed using the [Gamma Omega
 keyboard](https://github.com/unspecworks/gamma-omega) footprint from Ergogen.
