Documentation

• docs/README.md – structure + commands
• docs/setup-ssh-keys.md – SSH + secrets workflow

Layout

• flake.nix – flake entrypoint
• modules/ – shared module tree (flake outputs, NixOS, Home Manager, host matrix)
• modules/hosts/ – host matrix declaring which module sets each machine uses
• nixos/ – per-host NixOS entrypoints and hardware bits (e.g., nixos/pc/pc.nix)
• wallpapers/ – desktop assets

Why both modules/hosts and nixos/?

• modules/hosts/default.nix is the matrix that maps host names to module sets for both NixOS and Home Manager.
• nixos/<host>/<host>.nix is the system entrypoint that pulls in hardware and per-machine files.
