+To associate a component with a previously created entity call ``Entity::assign<C>()`` with the component type, and any component constructor arguments:
 
 ```c++
 // Assign a Position with x=1.0f and y=2.0f to "entity"
-entities.assign<Position>(entity, 1.0f, 2.0f);
+entity.assign<Position>(1.0f, 2.0f);
 ```
 
 You can also assign existing instances of components:
 
 ```c++
 boost::shared_ptr<Position> position = boost::make_shared<Position>(1.0f, 2.0f);
-entities.assign(entity, position);
+entity.assign(position);
