+# glennigen's NixOS config

+Flake-baseret NixOS config med KDE Plasma 6 + home-manager.

+├── home.nix                  # Brugerpakker (kun glennigen)

+```
+
+## Første gang på ny maskine
+
+```bash
+# Hardware-config genereres
+nixos-generate-config --show-hardware-config > hardware-configuration.nix
+
+# Byg systemet
+sudo nixos-rebuild switch --flake ~/nix#nixos
+```
+
+## Opdatering
+
+```bash
+cd ~/nix
+nix flake update              # opdater nixpkgs + home-manager
+sudo nixos-rebuild switch --flake .#nixos
+```
+
+## Tilføj pakker
+
+**System (alle brugere):** `modules/apps/native.nix`
