What is NixOS?

While Nix can run as a stand-alone package manager on any Linux system, and even on macOS, there's only so much that it can do without control over the rest of the system. NixOS is a Linux distribution that takes the concept of Nix a step further, by making it possible to use Nix for managing your entire system - from software, to services, to kernel settings, to container management, all using the same language.

This wiki is for learning both Nix and NixOS - NixOS-specific sections will be marked as such.
