 ## Deployment
 
 This code is deployed to Heroku as a static site, served by Rack. All files under the 'public' directory are served as static files (using [Rack::Static][] middleware). The [Rack::Rewrite][] middleware ensures that the index.html file is served for the root path: '/'. This is configured in the [config.ru][] file.
