Contribution Guidelines

We ask that you follow these guidelines when contributing to any of our repositories:

  • Use the rebase workflow to avoid unnecessary merge commits. This helps us keep a clean & linear commit history that's easy to review. We understand that this workflow can be intimidating for those new to git; please let us know if this is the case, we can help you clean up branch history before merging. See this tutorial for an explanation of the rebase workflow.
  • Avoid excessively large commits, as it's difficult for us to review.
  • Commit messages should follow conventional commits. We aren't super strict with these, but we prefer commits that are prefixed with feat: fix: or chore: at least.
  • Commit messages should be descriptive. Avoid generic and nondescript messages like "fix: fixed bug" or "fix: mistake".
