Some setup you must do manually if you haven’t yet:

1. Restart your server. app/cables has been added to the load path, and it
   is necessary to restart your web server and any non-async job queues.

   ActionCable requires that you use a servers such as Puma as your development
   webserver.

2. Ensure you're using a shared cache store. Rails by default uses an
   in-memory cache store, which can't be accessed between processes.
   http://guides.rubyonrails.org/caching_with_rails.html#activesupport-cache-filestore

     # config/environments/development.rb
     config.cache_store = :file_store, "tmp/cache"

3. Add the get_schwifty javascript to your application.js

     //= require get_schwifty

4. Setup your first cable to get schwifty

     rails g get_schwifty:cable Dashboard fibonacci
