Unofficial Documentation
Some documents don't fit in Gentoo's main repository or are too immature to be stored there. Or perhaps I'm writing a few documents with a license that doesn't match Gentoo's documentation license requirements. These documents find a home at this site.
Linux Sea
Linux Sea (PDF) is a work-in-progress book about (Gentoo) Linux as an operating system,
targeting the end-user. It covers Operating System concets, the Linux command-line, Linux/Unix concepts (permissions, users, processes ...) and system
management tasks. A simple changelog file is available at GitHub (together with the sources).

Gentoo Security Benchmark
Gentoo Security Benchmarks are security guides on how to configure Gentoo Linux and other services securely (hardening it). Sources are available on github.
