+## Contributing
+
+Do you think you have found a bug? Then please report it via the Github issue tracker. Make sure to
+attach any problematic files that can be used to reproduce the issue. Such files are also used to
+create regression tests that ensure that your bug will never return.
+
+When submitting pull requests, please prefix your commit messages with `fix:` or `feat:` for bug
+fixes and new features respectively. This is the
+[Conventional Commits](https://www.conventionalcommits.org/en/v1.0.0/) scheme that is used to
+automate some maintenance chores such as generating the changelog and inferring the next version
+number.
