Caution
Don't bother with this repository, it will not work with an actual Corne keyboard.
This repository is no longer relevant. Originally it existed to provide a quick way to get your own repository up and running with Keymap Editor, using a popular keyboard.
The biggest hurdle for most people was having a layout definition, which I've started to auto-generate when possible and in some cases I've started to compile them in the keymap-editor-contrib repo. If you want to see what the Keymap Editor's layout metadata looks like, check that repo out.
If you're looking for a starter for your ZMK keyboard code, look through ZMK's documentation Installing ZMK.
