+# 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.
