Use this section to choose the shortest path to your first useful DiffPal review.
Before you start, have:
- a repository on GitHub, GitLab, or Azure DevOps;
- permission to add CI configuration and repository secrets;
- one supported review provider or ACP-compatible agent;
- a pull request or merge request you can use for a trusted first test.
If the terms are new, read How DiffPal works and the Glossary first. Before adding provider secrets, read Secrets and fork PRs.

| Azure Pipelines | Azure Pipelines guide |
| Custom CI/CD | Custom CI/CD guide |
The fastest GitHub path uses the Codex API-key recipe because it is ready to copy. Codex is not the product boundary: the same DiffPal workflow works with other supported providers and ACP-compatible agents.

The GitHub quickstart uses review so the first run shows the full review
surface.
Use GitHub quickstart to install DiffPal in a new GitHub repository, then use Verify First Review to confirm the first run worked. After that, continue with Next Steps.
