 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. 
 
+## NGINX CONFIGURATION
+Override default configuration by adding `nginx.conf.erb` in the root directory
+
 ## Credits and License
 `buildpack-nginx` is licensed under the CC0 1.0 Universal license and has been informed by many similar projects on the web
