-# Dokku Buildpack: nginx
+# heroku-buildpack-nginx
 
 This is the official dokku buildpack for static websites, powered by nginx.
 
 ## Usage
 
-All static files that you want to serve should be in the root directory of your repository. No need to use a seperate `www` folder. `buildpack-nginx` will automatically download the buildpack, download NGINX, compile it, and install it. The next time you push your project, the buildpack will reuse the precompiled binaries.

+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).
 
 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.
