+* Lambdas are usually executed in the represented object's context. If your writing a `Decorator` representer and you need to execute lambdas in its context use the `:representer_exec` option.
 
+    class SongRepresenter < Representable::Decorator
+      property :title, :representer_exec => true, :getter => lambda {..}
+    end
+
+You can still access the represented object in the lambda using `represented`. In a module representer this option is ignored.
