Here is how you can create your own ZMK keymap for the Urchin.
- Fork this repository
- Enable actions on your fork. (click on the actions tab and enable actions)
- Edit the
zmk-urchin/config/urchin.keymap
file to your liking. (See the ZMK Codes reference) - When you push the changes an action will start that will build your firmware. If the action is successful the file will be available in it's assets. Check the ZMK docs if you need a visual guide.
