Approving a pull request with required reviews
If your repository requires reviews, pull requests must have a specific number of approving reviews from people with write or admin permissions in the repository before they can be merged.
Reverting a pull request
You can revert a pull request after it's been merged to the upstream branch.
Why are my commits linked to the wrong user?
GitHub Enterprise Cloud uses the email address in the commit header to link the commit to a GitHub user. If your commits are being linked to another user, or not linked to a user at all, you may need to change your local Git configuration settings, add an email address to your account email settings, or do both.
