Congratulations on taking the next step, and making use of your keyboard's open-source nature! There's so much power to unlock — this is going to be fun. :)
Here are some initial pointers to get you started:
- Use the documentation at https://docs.qmk.fm/ to set up your environment for building your firmware.
- Build your layout against https://github.com/zsa/qmk_firmware/ which is our QMK fork (instead of qmk/qmk_firmware). This is what Oryx (the graphical configurator) uses, so it's guaranteed to work.
- Create a folder with a simple name (no spaces!) for your layout inside the qmk_firmware/keyboards/ergodox_ez/keymaps/ folder.
- Copy the contents of the *_source folder (in the .zip you downloaded from Oryx) into this folder.
- Make sure you've set up your environment per the QMK docs so compilation would actually work.
- From your shell, make sure your working directory is qmk*firmware, then enter the command
make ergodox_ez:_layout_, substituting the name of the folder you created for "layout".
Good luck on your journey! And remember, if you get stuck, you can always get back to your original layout from Oryx.
