This is the default keymap for Georgi, it's based heavily off of the naps62 ErgoDox and the Gergo layout. It is both a ergonomic and programmer friendly keymap.
Ideally you should copy this directory and make your changes there. If you come up with a good layout submit a PR!
If you find yourself running out of space for dictionary entries, disabling mousekeys in rules.mk will save you about 4k for entries! Get a free 1k by deleting the Gaming layers from the keymap!
