+# Desktop Environments
+
+This directory contains system-level desktop environment configurations.
+
+## Available Desktop Environments
+
+- `hyprland.nix` - Dynamic tiling Wayland compositor
+- `plasma.nix` - KDE Plasma 6 desktop environment
+- `niri.nix` - Scrollable-tiling Wayland compositor
+- `base.nix` - Shared desktop settings (imported by all DEs)
+
+## Usage
+
+Import one desktop environment in your host configuration:
+
+```nix
+# modules/nixos/hosts/your-host.nix
+{
+  imports = [
+    ../desktops/hyprland.nix
+    # OR
+    # ../desktops/plasma.nix
+    # OR
+    # ../desktops/niri.nix
+  ];
+}
+```
+
+## Adding a New Desktop Environment
+
+1. Create a new file (e.g., `gnome.nix`)
+2. Import `./base.nix`
+3. Enable the desktop environment
+4. Add essential system packages
