+## A note on github tag action
+
+This repository is setup to automatically create tags on merge to
+master using .github/workflows/bumpversion.yml It uses
+https://github.com/mathieudutour/github-tag-action  to look for
+keywords in commit messages and determine what the new version should
+be.  The default if no keywords is found is to bump the patch version.
