Contributing

Read CONTRIBUTING.md for the code of conduct and the process for submitting pull requests, and use the pull request template when you open one. The code of conduct applies to every project space.

Unlike many kernel projects, RMP explicitly welcomes beginners. A good first contribution is a port to a chip you already own, a missing benchmark row, or a documentation fix — the platform layer is small enough to review.
