 distributions_]. Users are responsible for preparing dists for upload
 by putting them into the `dist/` folder prior to running this Action.

+> distribution packages, though. It is strongly advised to separate jobs
+> for building the OS-specific wheels from the publish job. This allows
+> one to (1) test exactly the same artifacts that are about to be
+> uploaded to PyPI, (2) prevent parallel unsynchronized jobs from
+> publishing only part of the dists asynchronously (in case when part of
+> the jobs fail and others succeed ending up with an incomplete release
+> on PyPI) and (3) make an atomic upload to PyPI (when part of the dists
+> appear on PyPI, installers like pip will use that version for the
+> dependency resolution but this may cause some environments to use
+> sdists while the wheels for their runtime is not yet available).

+> To implement this sort of orchestration, please use
+> `actions/upload-artifact` and `actions/download-artifact` actions for
+> sharing the built dists across stages and jobs. Then, use the `needs`
+> setting to order the build, test and publish stages.
