It must remain compatible with all supported board versions and stay easy to read. We are happy to review pull requests that align with that requirement. Feature work that is not suitable for `main` can still be linked from the README or kept in a dedicated feature branch. --- # Agent Instructions This documentation is published with GitBook.
