 ## Publishing (to PyPI)
-If the repository has been provided with a `PYPI_APIKEY` **Secret**
-the GitHub `pip-release` workflow action will automatically publish the package to
-PyPI when you create a new **Release**. The package version will be set using
-the release `tag_name`.
+We rely on out **release** GitHub workflow to publish to PyPI, something that
+is done automatically when the repository main branch is tagged.
