How to use

How to use

You give Lighthouse a URL to audit, it runs a series of audits against the page, and then it generates a report on how well the page did. 

From there, use the failing audits as indicators on how to improve the page. Each audit has a reference doc explaining why the audit is important, as well as how to fix it.
