+## Updating the workflow
+
+If a new change needs to be deployed a new tag needs to be created. Currently this process is not automatated, so you need to run:
+```
+git tag <tagname>
+git push origin --tags
+```
+This will allow you to test out the workflow first if you'd like (we have a ruleset called CLA check (dev)), otherwise update the main ruleset CLA-check with the correct tag.
