+If you don't want EVERY request to automatically be converted to :mobile if the device
+is mobile, you can enable the plugin with:
+
+    class ApplicationController < ActionController::Base
+      enable_mobile_fu
+    end
+
+And then in the controller that has mobile views you do:
+
+    class WhateverController < ApplicationController
+      before_filter :set_mobile_format
+    end
+
+If you want "test mode", or to always see the mobile view use:
+
+    class WhateverController < ApplicationController
+      before_filter :force_mobile_format
+    end
+
 I recommend that you setup a before_filter that will redirect to a specific page
 depending on whether or not it is a mobile request.  How can you check this?
