      To complete your setup with SSL certificates, run:
        /root/Tools/post_install_redirector.sh
      
      This script will guide you through:
      - Setting up Let's Encrypt certificates
      - Starting required services
      - Updating NGINX configuration
      
      For enhanced OPSEC, you can also randomize ports:
        /root/Tools/randomize_ports.sh
      
      Run these after you've configured your DNS records to point to this server.
