+# We recommend that maintainers use this Chrome/Firefox extension so that
+# squashed PRs will have the merged commit message default to the PR title and
+# description:  https://github.com/zachwhaley/squashed-merge-message
+#
+# This avoids the need to amend commits after the fact to match the desired PR
+# syntax.  As long as the PR itself is properly-formatted, this extension will
+# help you commit the right format to the repo, too.  This, in turn, feeds the
+# changelog and release workflows.

+  # NOTE: The automated PRs from release-please-action do not seem to trigger
+  # any of the default PR triggers (opened, synchronize, reopened).  So we need
+  # additional types.  This is a good set that makes it easy to trigger the
+  # workflow manually if needed.
