NixOS Documentation

Complete reference for NixOS and the Nix ecosystem, auto-generated from official repositories:

• nix.dev — tutorials, guides, best practices
• NixOS Manual — from NixOS/nixpkgs
• Nix Pills — progressive learning series
• Release Wiki — NixOS release process

The references/ directory contains full, unmodified documentation from those sources, updated daily.

How to Use

1. Identify the topic from the user's question and read the matching reference file from the tables below.
2. Base answers on those files. If more detail is needed, fetch the latest docs from the raw GitHub URLs in Live Fetching.
3. Distinguish between NixOS module options (services.nginx.enable = true;) and Nix language expressions (pkgs.mkDerivation { ... }).
4. Show examples using current syntax (configuration.nix or flake-based configs). When flakes are relevant, show both the classic (channels) and flakes approach.
5. For packaging, prefer the callPackage pattern over raw import.
6. Beginners: start with references/first-steps.md or references/nix-pills.md. Troubleshooting: check references/troubleshooting.md and references/faq.md first. System issues: references/nixos-administration.md.
