   1. Ensure you have defined default url options in your environments files. Here
      is an example of default_url_options appropriate for a development environment
      in config/environments/development.rb:
 
-       config.action_mailer.default_url_options = { :host => 'localhost:3000' }
+       config.action_mailer.default_url_options = { host: 'localhost:3000' }
 
      In production, :host should be set to the actual host of your application.
 
   2. Ensure you have defined root_url to *something* in your config/routes.rb.
      For example:
 
-       root :to => "home#index"
+       root to: "home#index"
 
   3. Ensure you have flash messages in app/views/layouts/application.html.erb.
      For example:
 
        <p class="notice"><%= notice %></p>
