+
+> **Manager Pattern**: _(Bonus pattern)_ Manages multiple entities of the same or similar type.
+
+Unlike the factory patterns which handle object creation or the
+mediator pattern which handles interaction between related objects, the 
+manager pattern has the role of managing multiple identical or related objects.
+
+For example in the Python standard library the [`Manager` object](https://docs.python.org/3/library/multiprocessing.html#multiprocessing.Manager)
+in the `multiprocessing` library manages shared objects between child
+processes.
