# Guides

- [Start the environment](https://kerno.gitbook.io/docs/guides/start-the-environment.md): Point Kerno at your running application so it can test against it.
- [Capture a baseline](https://kerno.gitbook.io/docs/guides/capture-a-baseline.md): Generate your first tests for an endpoint and review the plan before anything is written.
- [Validate code changes](https://kerno.gitbook.io/docs/guides/validate-code-changes.md): Re-run an endpoint's tests after a change, read the result, and bring the tests along when the change was intentional.
