  ## Deploying

  If you have previously run the `./bin/setup` script,
  you can deploy to staging and production with:

      $ ./bin/deploy staging
      $ ./bin/deploy production

  We currently use the following buildpacks:

  - heroku/nodejs
  - heroku/ruby
  - https://github.com/febeling/webpack-rails-buildpack.git

  Please be sure to configure these buildpacks in the same sequence
  presented here in both staging and production, or else the deploy will
  not work.
  MARKDOWN

  @app_builder.append_file "README.md", instructions
end
