### You should look at the following URL's in order to grasp a solid understanding# of Nginx configuration files in order to fully unleash the power of Nginx.# https://www.nginx.com/resources/wiki/start/# https://www.nginx.com/resources/wiki/start/topics/tutorials/config_pitfalls/# https://wiki.debian.org/Nginx/DirectoryStructure## In most cases, administrators will remove this file from sites-enabled/ and# leave it as reference inside of sites-available where it will continue to be# updated by the nginx packaging team.## This file will automatically load configuration files provided by other# applications, such as Drupal or Wordpress.
