Update Git repo from remote

The most common use case for this would be to sync a forked GitHub repo with the repo you forked it from. It is also the same process you would use in a non-Github workflow to keep your repo up-to-date with all the changes in a remote.

The example below assumes that you, want to:

• Name the remote “upstream”

• Want to update your main branch to match the remote’s main branch

  # 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/main:
  
  git fetch upstream
  
  # Make sure that you're on your main branch:
  
  git checkout main
  
  # Rewrite your main branch so that any commits of yours that
  # aren't already in upstream/main are replayed on top of that
  # other branch:
  
  git rebase upstream/main
