Development Setup

To get your development environment setup going, start at the basic setup docs, and make sure you can build and flash your own locally built firmware.


ZMK uses clang-format to ensure consist formatting for our source code. Before submitting your changes, make sure you've manually run clang-format, or have your IDE configured to auto-format on save.

The ZMK project is working towards, but not yet enforcing, the use of conventional commits for commit messages.

Further documentation and details will be provided here soon.
