Insufficient documentation for the programmatic unlighthouse api

[BennyAlex]

Details

Hello, my problem is that most of the documenation only focus on the cli and ci tools, but the informations on how to use unlighthouse in own scripts in not really there, exepct for this page: https://unlighthouse.dev/guide/getting-started/how-it-works
This page is missing key informations like imports. Where is hooks comming from?
Also there is no explanation how to install it. npm install unlighthouse ? or something else?

Thanks for any help.
