2. create all the folders and DNS entries on cPanel
3. WPMU DEV Dashboard
4. Domain Mapping plugin installed copied sunrise.php to "/home/content/29/11531829/html/wp-content/sunrise.php"
added "
define('WP_DEBUG', false);
define('WP_ALLOW_MULTISITE', true);

define('MULTISITE', true);
define('SUBDOMAIN_INSTALL', true);
define('DOMAIN_CURRENT_SITE', 'dryer-vent-duct-cleaning.com');
define('PATH_CURRENT_SITE', '/');
define('SITE_ID_CURRENT_SITE', 1);
