# Original post: http://stackoverflow.com/a/7244456   # 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
