  ==> Caveats
  Docroot is: /opt/homebrew/var/www
  
  The default port has been set in /opt/homebrew/etc/nginx/nginx.conf to 8080 so that
  nginx can run without sudo.
  
  nginx will load all files in /opt/homebrew/etc/nginx/servers/.
  
  To have launchd start nginx now and restart at login:
    brew services start nginx
  Or, if you don‘t want/need a background service you can just run:
    nginx
