+Assisted injection
+------------------
+Sometimes there are classes that have injectable and non-injectable parameters in their
+constructors. Let's have for example::
+
+    >>> Database = Key('Database')
+    >>> class User(object):
+    ...     def __init__(self, name):
+    ...         self.name = name
+
+    >>> class UserUpdater(object):
+    ...     @inject(db = Database)
+    ...     def __init__(self, db, user):
+    ...         pass 
+
+ You may want to have database connection ``db`` injected into ``UserUpdater`` constructor,
+ but in the same time provide ``user`` object by yourself, and assuming that ``user`` object
+ is a value object and there's many users in your application it doesn't make much sense
+ to inject objects of class ``User``. 
+
+ In this situation there's technique called Assisted injection::
+
+    >>> UserUpdaterFactory = Key('UserUpdaterFactory')
+    >>> def module(binder):
+    ...     binder.bind(UserUpdaterFactory, to=AssistedFactoryProvider(UserUpdater))
+
+    ... injector = Injector(module)
+    ... factory = injector.get(UserUpdaterFactory)
+    ... user = User('John')
+    ... user_updater = factory.create(user=user)
+
+ This way we don't make ``UserUpdater`` directly injectable - we provide injectable factory.
+ Such factory has ``create(**kwargs)`` method which takes non-injectable parameters, combines
+ them with injectable dependencies of ``UserUpdater`` and calls ``UserUpdater`` initializer
+ using all of them.
