+# Example: Enabling LXQt with Niri Window Manager
+
+To use LXQt with Niri as the window manager in your NixOS configuration, add the following to your host configuration:
+
+```nix
+{
+  imports = lib.flatten [
+    # ... other imports ...
+    "hosts/common/optional/lxqt-niri.nix"
+    "hosts/common/optional/gdm.nix"  # or sddm.nix for SDDM display manager
+    # ... other imports ...
+  ];
+}
+```
+
+## What this provides
