    We've set up the basics of webpack-rails for you, but you'll still
    need to:

      1. Add the 'application' entry point in to your layout, and
        e.g. <%= javascript_include_tag *webpack_asset_paths('application') %>
      2. Add an element with an id of 'app' to your layout
      3. Enable hot module replacement by adding <script src="http://localhost:3808/webpack-dev-server.js"></script> to your layout
      4. Run 'foreman start' to run the webpack-dev-server and rails server

      Example app/views/layouts/application.html.erb
      <!DOCTYPE html>
      <html>
        <head>
          <title>WebpackDemo</title>
          <%= stylesheet_link_tag    'application', media: 'all' %>
          <%= javascript_include_tag 'application' %>
          <script src="http://localhost:3808/webpack-dev-server.js"></script>
          <%= csrf_meta_tags %>
        </head>
        <body>

          <%= yield %>
          <%= javascript_include_tag *webpack_asset_paths('application') %>
        </body>
      </html>


    See the README.md for this gem at
    https://github.com/wdjungst/webpack-rails-react/blob/master/README.md
    for more info.

    Thanks for using webpack-rails-react!
