# Add the remote, call it "upstream":
git remote add upstream https://github.com/desktop-cgi/desktop-cgi.git

# Fetch all the branches of that remote into remote-tracking branches
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
