Git rebase into forked repo

Excerpted from here

  1. Add the remote (original repo that you forked) and call it “upstream”
git remote add upstream https://github.com/original-repo/goes-here.git
  1. Fetch all branches of remote upstream
git fetch upstream
  1. Rewrite your master with upstream’s master using git rebase.
git rebase upstream/master
  1. Push your updates to master. You may need to force the push with “--force”.
git push origin master --force
