  +## Angular: Commit Header
  +```
  +It looks like you need to update your commit header to match our requirements. This is different from the PR title. To update the commit header, use the command `git commit --amend` and update the header there.
  +
  +Once you've finished that update, you will need to force push using `git push [origin name] [branch name] --force`. That should address this.
  +```
  +
  +## Angular: Rebase and Squash
  +```
  +Please rebase and squash your commits. To do this, make sure to `git fetch upstream` to get the latest changes from the angular repository. Then in your branch run `git rebase upstream/main -i` to do an interactive rebase. This should allow you to fixup or drop any unnecessary commits. After you finish the rebase, force push using `git push [origin name] [branch name] --force`.
