A peer created a new branch. I ran
git checkout newBranch
Because as far as I understand it
git branch only lists your local branches. Your repository still has the remote branch there, hence why you can checkout the branch. And once you checkout that branch you've create your local version of said branch.
git branch now shows the branch after you checked it out.
git branch -a - Lists all branches, both local and remote-tracking branches git branch or git branch --list - Lists all existing local branches git branch -r - Lists remote-tracking branches
