 h2. Usage
 
 To give this some context; this is how we use @Yaml2Env@ to initialize "Hoptoad":http://hoptoadapp.com:
 
 <pre>
-  Yaml2Env.load 'config/hoptoad.yml', {'HOPTOAD_API_KEY' => 'api_key'}
+  Yaml2Env.load! 'config/hoptoad.yml', {'HOPTOAD_API_KEY' => 'api_key'}
 
+  # ...or if a warning note in the logs is enough:
+  #   Yaml2Env.load 'config/hoptoad.yml', {'HOPTOAD_API_KEY' => 'api_key'}
+
   if defined?(HoptoadNotifier)
     HoptoadNotifier.configure do |config|
       config.api_key = ENV['HOPTOAD_API_KEY']
     end
   end
