-  Can be used for "pre-verifying" a PR before uploading the artifacts to the server. It checks
-  whether the author of the PR is a member of one of the specified GitHub teams (therefore allowed
-  to upload build artifacts) or the PR has the specified "trusted PR" label (meaning it has been

   Can be used for updating the docker container (and image) based on the latest changes checked out
   from a git repository. See [here](vm-setup--update-docker-container.md) for more info.
