+# Script: hass_backup.sh
+# Description: This script securely backs up Home Assistant to a designated 
+#              mounted drive using rsync. It includes pre-run checks to ensure 
+#              the source files and destination are valid, and sends ntfy 
+#              notifications for each task.
+# Usage:       sudo ./hass_backup.sh
+# Notes:       This script may require sudo/root privileges to access files.
+# ==============================================================================
+
+# ==============================================================================
+# Define Variables for Source and Destination
+# ==============================================================================
+# This makes the script easier to read and modify.
