+  # The following options are available, assuming the engine is mounted as:
+  #
+  #     mount MyEngine, at: '/my_engine'
+  #
+  # The router that invoked `devise_for`, in the example above, would be:

+  # config.omniauth_path_prefix = '/my_engine/users/auth'
+
+  # ==> Turbolinks configuration
+  # If your app is using Turbolinks, Turbolinks::Controller needs to be included to make redirection work correctly:

+  # ActiveSupport.on_load(:devise_failure_app) do
+  #   include Turbolinks::Controller
+  # end
+
+  # ==> Configuration for :registerable
