 This section is intended for maintainers of the project. It describes how new
 versions of StagPy are released on PyPI.
 
-Version numbers are tracked with git tags thanks to `setuptools_scm`. Marking
-a new version merely consists in tagging the `HEAD` of the `master` branch.
+The version number lives in `pyproject.toml`. Releases are tagged, with the
+annotations of the tag containing release notes.
 Please make sure to always provide a patch version number (i.e. use a version
 number with *three* levels such as `1.0.0` instead of `1.0`).
 
 ```sh title="shell"
+# edit version number in pyproject.toml
+git add pyproject.toml
+git commit -m "release vX.Y.Z"
 git tag -a vX.Y.Z
 git push --follow-tags
 ```
