+* nixos-configuration
+
+This repository is for my [[https://nixos.org/][NixOS]] configuration.
+
+** Setup
+
+1. Clone or symlink to =/etc/nixos=
+2. If necessary, re-create relevant files in =./private=
+3. Run =nixos-generate-config= if on a fresh machine
+4. Remove =configuration.nix=
+5. Link a machine configuration to =configuration.nix=
+6. Apply configuration with =nixos-rebuild= or =nixos-install=
