It looks like you already use the private repo but you can read about authors working in the public repo for more information.

If you do need help getting set up to work in the private repo, see Get started contributing to the Microsoft Learn platform.

Important: Contributor guidance has moved to https://learn.microsoft.com/help/

After you make your changes in the private repo, review the articles on staging, and fix any validation issues, you can add the #sign-off comment to let PR reviewers know that the updates are ready to be merged.
