+# Example: Swap GNOME Desktop with COSMIC Desktop
+###############################################################################
+# This example demonstrates replacing the GNOME desktop environment with
+# System76's COSMIC desktop from their COPR repository.
+#
+# COSMIC is a new desktop environment built in Rust by System76.
+# https://github.com/pop-os/cosmic-epoch
+#
+# To use this script:
+# 1. Rename to remove .example extension: mv 30-cosmic-desktop.sh.example 30-cosmic-desktop.sh
+# 2. Build - scripts run in numerical order automatically
+#
+# WARNING: This removes GNOME and replaces it with COSMIC. Only use this if
+# you want COSMIC as your desktop environment instead of GNOME.
