 ## Configuration
 
-You can override the nginx root via setting the `NGINX_ROOT` environment variable. This should be a relative path in your repository (for example `dokku config:set <app> NGINX_ROOT=_site` if you are deploying a Jekyll site).
+### Custom nginx root
+
+You can override the nginx root via setting the `NGINX_ROOT` environment variable. This should be a relative path in your repository.
+
+```shell
+# where the app is named `static-app`
+# and the root dir is _site
+dokku config:set static-app NGINX_ROOT=_site
+````
+
+### Custom nginx config file
 
 You may completely override the built-in nginx config by placing an `app-nginx.conf.sigil` file in the root, modeled after our own [`conf/app-nginx.conf.sigil`](https://github.com/dokku/buildpack-nginx/blob/master/conf/app-nginx.conf.sigil). This will be used inside of the container, and not by the host Dokku instance. See the [sigil project](https://github.com/gliderlabs/sigil) for more information concerning the sigil format.
