## What it is
An exhaustive, curated checklist of front-end web performance best practices covering HTML, CSS, fonts, images, and JavaScript, with prioritized rules and explanations. It also links to performance testing and monitoring tools and related reference articles.

## Use cases

- you are looking for back-end or server-side performance guidance
- you need executable code or a CLI rather than documentation
