+# Making a release
+
+Releases are built and uploaded to [PyPI][pypi] by the [Build + Test workflow][ci]
+(`.github/workflows/ci.yml`). Publishing a GitHub release starts the workflow,
+which builds and tests the wheels and the sdist, then uploads them to PyPI using
+trusted publishing. Pushes and pull requests run the same builds and tests but
+never upload anything.
+
+## Updating the CastXML version
+
+Skip this section if the release doesn't change the CastXML version.
+
+Available CastXML archives can be found
+[here](https://data.kitware.com/#folder/57b5de948d777f10f2696370).
+
+1. Install `girder-client`:
+
+   ```bash
+   pip install girder-client
+   ```
+
+2. Run `scripts/update_castxml_version.py` with the CastXML version `X.Y.Z` to
+   package. For example:
+
+   ```bash
+   release=0.4.5
+   python scripts/update_castxml_version.py ${release}
+   ```
+
+   It updates the archive URLs and checksums, the version in `README.md`, and
+   the expected version in the tests:
+
+   ```
+   Collecting URLs and SHAs from 'https://data.kitware.com/#folder/57b5de948d777f10f2696370'
+   Collecting URLs and SHAs from 'https://data.kitware.com/#folder/57b5de948d777f10f2696370' - done
+   Updating 'CastXMLUrls.cmake' with CastXML version 0.4.5
+   Updating 'CastXMLUrls.cmake' with CastXML version 0.4.5 - done
+   Updating README.md
+   Updating README.md - done
+   Updating tests/test_distribution.py
+   Updating tests/test_distribution.py - done
+   ```
+
+3. Commit the changes on a branch named `update-to-castxml-X.Y.Z`:
+
+   ```bash
+   git checkout -b update-to-castxml-${release}
+   git add CastXMLUrls.cmake README.md tests/test_distribution.py
+   git commit -m "Update to CastXML ${release}"
+   ```
+
+4. Open a pull request, and merge it once CI passes.
+
+## Cutting the release
+
+1. Choose the release version.
+
+   ```bash
+   release=X.Y.Z
+   ```
+
+   The git tag *is* the package version: setuptools-scm reads it at build time.
+   Use the bare form `X.Y.Z` with no `v` prefix. For a packaging-only fix to a
+   version that's already on PyPI, use `X.Y.Z.postN`.
+
+2. Make sure your local `master` matches what CI tested:
+
+   ```bash
+   git checkout master
+   git pull origin master
+   ```
+
+3. Tag the release and push the tag:
+
+   ```bash
+   git tag --sign -m "CastXML-python-distributions ${release}" ${release} master
+   git push origin ${release}
+   ```
+
+   Signing the tag with a [GPG key][gpg] is recommended. Pushing the tag on its
+   own doesn't start a build.
+
+4. Publish a GitHub release for the tag. This is what starts the release build:
+
+   ```bash
+   gh release create ${release} --verify-tag --title "CastXML-python-distributions ${release}" --generate-notes
+   ```
+
+   Alternatively, in the GitHub UI, go to **Releases → Draft a new release**,
+   choose the tag, and click **Publish release**. Saving a draft doesn't start
+   the workflow; only publishing does.
+
+5. Follow the run in the repository's **Actions** tab, or with `gh run watch`.
+   If the `pypi` environment requires reviewers, the `publish` job waits until
+   you approve it with **Review deployments** on the run page.
+
+6. Once the run finishes, check that the wheels and sdist are on [PyPI][pypi].
+
+7. Test the installation in a clean environment:
+
+   ```bash
+   python -m venv /tmp/castxml-${release}-test
+   /tmp/castxml-${release}-test/bin/pip install castxml==${release}
+   /tmp/castxml-${release}-test/bin/castxml --version
+   rm -rf /tmp/castxml-${release}-test
+   ```
+
+## If something goes wrong
+
+- **The build or tests fail:** nothing was uploaded, because the `publish` job
+  only runs after every build succeeds. Fix the problem on `master`, delete the
+  release and its tag, and start again from step 2:
+
+  ```bash
+  gh release delete ${release} --cleanup-tag --yes
+  git tag -d ${release}
+  ```
+
+- **A broken release reached PyPI:** PyPI never accepts the same version twice,
+  even after it's deleted. Fix the problem and release `X.Y.Z.post1`.

-================
-Making a release
-================
-
-A core developer should use the following steps to create a release `X.Y.Z` of
-**CastXML-python-distributions** on `PyPI`_.
-
-This is usually done after :ref:`updating_castxml_version`.
-
--------------
-Prerequisites
--------------
-
-* All CI tests are passing on `AppVeyor`_, `CircleCI`_ and `Travis CI`_.
-
-* You have a `GPG signing key <https://help.github.com/articles/generating-a-new-gpg-key/>`_.
-
--------------------------
-Documentation conventions
--------------------------
-
-The commands reported below should be evaluated in the same terminal session.
-
-Commands to evaluate starts with a dollar sign. For example::
-
-  $ echo "Hello"
-  Hello
-
-means that ``echo "Hello"`` should be copied and evaluated in the terminal.
-
-
----------------------
-`PyPI`_: Step-by-step
----------------------
-
-1. Make sure that all CI tests are passing on `AppVeyor`_, `CircleCI`_ and `Travis CI`_.
-
-
-2. Download the latest sources
-
-  .. code::
-
-    $ cd /tmp && \
-      git clone git@github.com:CastXML/CastXML-python-distributions CastXML-python-distributions-release && \
-      cd CastXML-python-distributions-release
-
-3. List all tags sorted by version
-
-  .. code::
-
-    $ git fetch --tags && \
-      git tag -l | sort -V
-
-
-4. Choose the next release version number
-
-  .. code::
-
-    $ release=X.Y.Z
-
-  .. warning::
-
-      To ensure the packages are uploaded on `PyPI`_, tags must match this regular
-      expression: ``^[0-9]+(\.[0-9]+)*(\.post[0-9]+)?$``.
-
-
-5. In `README.md`, update `PyPI`_ download count after running ``pypistats overall CastXML``
-   and commit the changes.
-
-  .. code::
-
-    $ git add README.rst && \
-      git commit -m "README: Update download stats"
-
-  ..  note::
-
-    To learn more about `pypistats`, see https://pypi.org/project/pypistats/
-
-
-6. Tag the release
-
-  .. code::
-
-    $ git tag --sign -m "CastXML-python-distributions ${release}" ${release} master
-
-  .. warning::
-
-      We recommend using a `GPG signing key <https://help.github.com/articles/generating-a-new-gpg-key/>`_
-      to sign the tag.
-
-
-7. Publish the release tag
-
-  .. code::
-
-    $ git push origin ${release}
-
-  .. note:: This will trigger builds on each CI services and automatically upload the wheels \
-            and source distribution on `PyPI`_.
-
-8. Check the status of the builds on `AppVeyor`_, `CircleCI`_ and `Travis CI`_.
-
-9. Once the builds are completed, check that the distributions are available on `PyPI`_.
-
-10. Create a clean testing environment to test the installation
-
-  .. code::
-
-    $ pushd $(mktemp -d) && \
-      mkvirtualenv CastXML-${release}-install-test && \
-      pip install CastXML && \
-      castxml --version
-
-  .. note::
-
-      If the ``mkvirtualenv`` command is not available, this means you do not have `virtualenvwrapper`_
-      installed, in that case, you could either install it or directly use `virtualenv`_ or `venv`_.
-
-11. Cleanup
-
-  .. code::
-
-    $ popd && \
-      deactivate  && \
-      rm -rf dist/* && \
-      rmvirtualenv CastXML-${release}-install-test
-
-12. Publish master branch
-
-  .. code::
-
-    $ git push origin master
-
-.. _virtualenvwrapper: https://virtualenvwrapper.readthedocs.io/
-.. _virtualenv: http://virtualenv.readthedocs.io
-.. _venv: https://docs.python.org/3/library/venv.html

-
-============================
-Updating the CastXML version
-============================
-
-A developer should use the following steps to update the version ``X.Y.Z``
-of CastXML associated with the current CastXML python distributions.
-
-Available CastXML archives can be found `here <https://data.kitware.com/#folder/57b5de948d777f10f2696370>`_.
-
-1. Install `girder-client`::
-
-    $ pip install girder-client
-
-2. Execute `scripts/update_castxml_version.py` command line tool with the desired
-   ``X.Y.Z`` CastXML version available for download. For example::
-
-    $ release=0.4.5
-    $ python scripts/update_castxml_version.py ${release}
-
-    Collecting URLs and SHAs from 'https://data.kitware.com/#folder/57b5de948d777f10f2696370'
-    Collecting URLs and SHAs from 'https://data.kitware.com/#folder/57b5de948d777f10f2696370' - done
-    Updating 'CastXMLUrls.cmake' with CastXML version 0.4.5
-    Updating 'CastXMLUrls.cmake' with CastXML version 0.4.5 - done
-    Updating README.md
-    Updating README.md - done
-    Updating docs/update_castxml_version.rst
-    Updating docs/update_castxml_version.rst - done
-    Updating tests/test_distribution.py
-    Updating tests/test_distribution.py - done
-
-3. Create a topic named `update-to-castxml-X.Y.Z` and commit the changes.
-   For example::
-
-    release=0.4.5
-    git checkout -b update-to-castxml-${release}
-    git add CastXMLUrls.cmake README.md docs/update_castxml_version.rst tests/test_distribution.py
-    git commit -m "Update to CastXML ${release}"
-
-4. Create a `Pull Request`.
-
-5. If all CI tests are passing, merge the topic and consider `making a new
-   release <https://github.com/CastXML/CastXML-python-distributions/blob/master/docs/make_a_release.rst>`_.
