How to: How do I author custom audits to extend Lighthouse?
> **Tip**: see [Lighthouse Architecture](./docs/architecture.md) for more information
on terminology and architecture.

Lighthouse can be extended to run custom audits and gatherers that you author.
This is great if you're already tracking performance metrics in your site and
want to surface those metrics within a Lighthouse report.

If you're interested in running your own custom audits, check out our
[Custom Audit Example](./docs/recipes/custom-audit) over in recipes.
