Each guide answers one question in a few steps and links to the pages that cover the details.

| Guide | What it covers |
| --- | --- |
| [Move your GitHub Actions workflows to Diffinery](https://diffinery.com/docs/guides/move-github-actions-workflows) | What runs unchanged, runner labels and sizes, marketplace actions, secrets, caches, Docker, OIDC, environments, self-hosted runners for macOS, Windows and Arm, and a checklist. |
| [Make your CI faster on Diffinery](https://diffinery.com/docs/guides/faster-ci) | Runner sizes and automatic sizing, caching, setup and Docker head starts, matrices, cancelling superseded runs, and measured numbers. |
| [Give an AI coding agent its own account, with guardrails](https://diffinery.com/docs/guides/ai-agent-with-guardrails) | Create an agent and its token, what the server enforces, connecting Claude Code, Codex or any MCP client, reviewing and merging agent pull requests, and auditing what agents did. |
| [Run Diffinery CI while your code stays on GitHub](https://diffinery.com/docs/guides/mirror-from-github) | Mirror every GitHub push to Diffinery, copy the secrets your workflows need, and fail on GitHub when Diffinery's runs fail. |
