 The above settings will generate something link `100-some-title-page`. By overriding `to_param` method you don't have to change a thing on your app routes.
 
 If you want to generate unique permalink, use the `:unique` option:
 
-	class Page < ActiveRecord::Base
-	  permalink :title, :unique => true, :to_param => :permalink
-	end
+    class Page < ActiveRecord::Base
+      permalink :title, :unique => true, :to_param => :permalink
+    end
 
 The permalink is generated using `ActiveSupport::Multibyte::Chars` class; this means that characters will properly replaced from `áéíó` to `aeio`, for instance.
 
 The permalink is created when `before_validation` callback is evaluated. This plugin also tries
 to generate a permalink when `before_save` callback is evaluated and the instance has no permalink set.
+
+You can force the permalink generation by setting the `:force` option.
+
+    class Page < ActiveRecord::Base
+      permalink :title, :force => true
+    end
