+## Contributing
+
+To contribute to this repository you must create a pull request into main. Before merging you must increase the version number in the [pyproject.toml](./pyproject.toml) file (see [this guide](https://packaging.python.org/en/latest/specifications/version-specifiers/#version-specifiers) for versioning scheme).
+A GitHub check will ensure that the repository version is valid and greater than the version on the main branch. This is essential as we currently do not publish to PyPi.
+The pull request may be merged only when this check passes.  Bypassing this check is not permitted, nor are direct pushes to main. Once merged, a version tag is automatically generated.
+
+> [!IMPORTANT]
+> Tests in this repository are run by both the [iblrig](https://github.com/int-brain-lab/iblrig) and [ibllib](https://github.com/int-brain-lab/ibllib) CI.
