Kefir publishes a pre-launch FAQ

The FAQ announcement preceded the opening of Early Access by about a month. The durable documentation is the help centre, organised into Getting Started, Looting and Robbing, Police and Arrests, Money, Transport, Districts, Settlements and Base, Updates and Suggestions, Monetization, Account, and Troubleshooting and Support.

That structure is the backbone of this site's database. Each entry here maps to one or more specific help-centre articles, and the FAQ page links to the articles whose full answers have not been independently checked here.
