+      Pushing a release tag results in this action running twice:
+
+      Once to run ``towncrier`` and consolidate the changelog fragments into a
+      single update of the CHANGELOG file.
+
+      Once to release the package after the CHANGELOG file has been updated.
+
+      There are two options when making a release for your repository:
+
+      1. You pushed a tag from a release branch (``release-from-main`` is ``false``)
+
+        This is the most common case for PyAnsys repositories. The following steps are
+        performed when ``release-from-main`` is ``false``:
+
+        a) Find a release branch that has the same major and minor version of the
+        tag that was pushed. For example, if your tag was "v0.1.2", it looks for
+        a release branch named "release/0.1". If the release branch cannot be found, a
+        temporary branch is used named "maint/changelog-update-vTAG_VERSION".
+
+        b) Checkout the release or temporary branch, update the CHANGELOG file
+        using ``towncrier``, and push the updates to the respective branch.
+
+        c) Checkout the main branch and create a pull request branch named
+        "maint/vTAG_VERSION-changelog". Delete the pull request branch from the remote
+        if it exists, checkout the pull request branch, cherry pick the commit
+        containing the CHANGELOG file changes from the previous step, push the
+        pull request branch, and create a pull request from the branch into main.
+
+        d) Checkout the release or temporary branch, delete the tag locally and
+        on the remote, create the new tag locally, and push the tag on the remote.
+        Delete the temporary branch if one was used to update the CHANGELOG file.
+
+        e) Exit on error if the CHANGELOG is updated, so that the package is not released from
+        this instance of the workflow.
+
+      2. You pushed a tag from the main branch (``release-from-main`` is ``true``)
+
+        The following steps are performed when ``release-from-main`` is ``true``:
+
+        a) Checkout the main branch, update the CHANGELOG file using ``towncrier``,
+        and push the updates to the main branch.
+
+        b) Checkout the main branch, delete the tag locally and on the remote,
+        create the new tag locally, and push the new tag on the remote.
+
+        c) Exit on error if the CHANGELOG is updated, so that the package is not released from
+        this instance of the workflow.
