Go and check out Chorizo!'s new Help Center. We extended the existing tutorials and provide a smooth overview about the current documentation. Included is an overview about all the scanner plugins Chorizo! is using and explain a bit what each plugin does.
There are "Getting Started" guides offered, video tutorials, details on each of the plugins (PHPversions, XSS plugin, Session injection, etc), some of the features of the scanner, and some general troubleshooting information.
