+
+  1. Connect to the SPICE display:
+     remote-viewer spice://127.0.0.1:5930
+
+  2. Follow the graphical installer in the window
+     - Choose "Install Xubuntu"

+     - Complete the installation process
+
+  Note: This is a manual desktop installation, not automated.
+
+  Required: Install SPICE viewer first
+    brew install virt-viewer
+
+  After installation, the desktop will boot into the GUI.
