 # Prerequisites:
-# - Run as root on a fresh Debian 12 or Ubuntu server (e.g., sudo ./setup_harden_debian_ubuntu.sh or run as root ./setup_harden_debian_ubuntu.sh).
+# - Run as root on a fresh Debian 12 or Ubuntu server (e.g., sudo ./du_setup.sh or run as root ./du_setup.sh).
 # - Internet connectivity is required for package installation.

 #
 # Options:
 #   --quiet: Suppress non-critical output for automation. (Not recommended always best to review all the options)
 #
 # Notes:
-# - The script creates a log file in /var/log/setup_harden_debian_ubuntu_*.log.
+# - The script creates a log file in /var/log/du_setup_*.log.
 # - Critical configurations are backed up before modification. Backup files are at /root/setup_harden_backup_*.
