+# Memento
+
+## Purpose
+
+Provide the ability to restore an object to its previous state (undo via rollback).
+
+The memento pattern is implemented with three objects: the originator, a caretaker and a memento.
+The originator is some object that has an internal state.
+The caretaker is going to do something to the originator, but wants to be able to undo the change.
+The caretaker first asks the originator for a memento object. Then it does whatever operation (or sequence of operations) it was going to do.
+To roll back to the state before the operations, it returns the memento object to the originator.
+The memento object itself is an opaque object (one which the caretaker cannot, or should not, change).
+When using this pattern, care should be taken if the originator may change other objects or resources - the memento pattern operates on a single object.
+
+## Examples
+
+* The seed of a pseudorandom number generator
+* The state in a finite state machine
