# Add the remote, call it "upstream": git remote add upstream https://github.com/whoever/whatever.git # Fetch all the branches of that remote into remote-tracking branches, # such as upstream/master: git fetch upstream # Make sure that you're on your master branch: git checkout master # Rewrite your master branch so that any commits of yours that # aren't already in upstream/master are replayed on top of that # other branch: git rebase upstream/master
