Github: Import upstream branch into fork

1. Make sure you’ve pulled the new upstream branch into your local repo:

   • First, ensure your working tree is clean (commit/stash/revert any changes)
   • Then, git fetch upstream to retrieve the new upstream branch

2. Create and switch to a local version of the new upstream branch (newbranch):

   • git checkout -b newbranch upstream/newbranch

3. When you’re ready to push the new branch to origin:

   • git push -u origin newbranch

The -u switch sets up tracking to the specified remote (in this example, origin)
