+  # is mountable, there are some extra configurations to be taken into account.
+  # 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

+  # end
