Add section on pruning deleted remote branches
Since gitlab uses branches for merge requests there is going to be a lot of branches being created and deleted. The issue is that when a branch is deleted from the remote gitlab repository it is not deleted from the users local references. This could result in the users local copy showing lots of remote branches that have been deleted from the remote-repository.
List branches on the local machine
git branch -a
List branches that can be delete/pruned on your local
git remote prune origin --dry-run
Actually delete/prune the local references
git remote prune origin
