+# OCM Helper Scripts
+
+These scripts help in the process of releasing new versions of `ocm`.
+
+Once all changes for a specific release are in `main`, the next step is to
+create a release commit:
+
+	./hack/commit-release.sh
+
+This creates a new branch, updates the OCM build version and changelog file
+then commits and pushes to GitHub. Any potentially destructing action has a
+confirmation prompt.
+
+Once this new branch is pushed, someone has to merge it. Once merged, make sure
+to update your local copy. Then you can tag the actual release:
+
+	./hack/tag-release.sh
+
+This will create a new annotated tag and push it to the upstream OCM
+repository.
+
+Now that the tag is in place, you will go to the
+[tags page](https://github.com/openshift/ocm/tags) and edit the latest one. In
+there make sure that the release title and description match the release tag
+annotation.
+
+Publish the release and you're done.
