You need to add a new data domain including a table (mshop_faq), create
manager and item implementations, add a panel to the admin backend for
managing these FAQs, create a controller in the ai-controller-frontend
extension and add a HTML client component as well as a JSON API endpoint.

The CMS extension is a good code base for copy&paste of the necessary code:

For 2021.10, the code looks a bit different, especially the migrations
because we've switched to Upscheme (https://upscheme.org):
