+## Contributing
+
+PRs are appreciated, just make sure your PR title starts with one of the
+following keywords so that the CI works:
+- `[MAJOR]`: breaking changes
+- `[MINOR]`: feature changes
+- `[PATCH]`: fixes
+- `[CONFIG]`: changes only related to GitHub (CI, .gitignore, etc.) -> won't trigger a package release
