@adyoun2 Looks like you are having some issues with your Git, I've been
there many times... But I'm sure we can get it working.
Make sure that after you rebase your Github fork you push the changes back
to Github. Right now Github thinks you made a lot of extra changes to your
branch that you didn't (thus the ~500 changed files). Also, when you squash,
don't squash your changes in with another users, just squash your own changes.
