 # Important: This script should never cause the pipeline to fail, so that the tags can be created outside of it.
+# To run it locally, you need pass the version, i.e. export VERSION=2.39.x
 # If run locally, it:
-# - does not need to run inside pmm-submodules as it clones all the necessary repos
+# - it clones the pmm-submodules repo and checks out the branch corresponding to the version
 # - does not need to configure git to push using ssh, this user should set it all up ahead of time
 # - will use the user's creds and email to tag the repos, therefore sufficient permissions are required
