# Plan on Pull Request

Review infrastructure changes before merging a pull request. Run an Atmos plan in GitHub Actions and publish the results as job summaries, checks, and pull request comments.

Use [Setup Atmos](/integrations/github-actions/setup-atmos) to pin the Atmos container version, enable [native CI reporting](/ci#quick-start), and configure [authentication and permissions](/integrations/github-actions/authentication) for your repository.
