# 7. Use Nginx mode
# 7. Use DNS mode:
**(requires you to be root/sudoer, since it is required to interact with Nginx server)**
If you are running a web server, Apache or Nginx, it is recommended to use the `Webroot mode`.
Particularly, if you are running an nginx server, you can use nginx mode instead. This mode doesn't write any files to your web root folder.
Just set string "nginx" as the second argument.
It will configure nginx server automatically to verify the domain and then restore the nginx config to the original version.
So, the config is not changed.
