Is there official documentation for any distro accessible to complete *nix beginners? That is, aimed at the 95% least technical computer users:Assumes an already installed desktop system with working hardware driversNames the already installed programs for common tasks, such as Firefox and LibreOfficeExplains on a very basic level how to launch programs, install programs and upgrades, and shutting down the machineNo mention of command lines, firewalls, dual booting, licenses or other technical/ideological subjectsThe idea is to give people even remotely curious about Linux an idea about just how similar modern *nix desktops are to well known Windows versions, and which immediate practical benefits they get: free as in beer forever, fast startup, simple software installation, and safety against viruses by default.
