+## 5 Release
+
+To release a new version of Mattermost Operator you need to:
+
+- Have the repository up-to-date
+- Have the remote upstream configured
+- Have a clean repo, not pending commits and changes
+
+We have a script that changes some files, commit those changes and then tag the main branch.
+
+To run you can issue the following command:
+
+```console
+./scripts --tag=<DESIRED_TAG>
+````
+
+where:
+
+- <DESIRED_TAG> can be 1.10.1 for example
