Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# NixOS Documentation

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

- [nix.dev](https://nix.dev/) - tutorials, guides, best practices
- [NixOS Manual](https://nixos.org/manual/nixos/stable/) - from `NixOS/nixpkgs`
- [Nix Pills](https://nixos.org/guides/nix-pills/) - progressive learning series
- [Release Wiki](https://nixos.github.io/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`.

How to install

The exact contents, by fingerprint
mdr add marceloeatworld/nixos-ai-skill/nixos@sha256:1a06935874bc6544

The line at the top of this page pins the label v0.2.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
