+## Mediator
+
+Mediator pattern has behavioral purpose and applies on objects.
+The pattern defines an object that encapsulates how a set of objects interact.
+It promotes loose coupling by keeping objects from referring to each
+other explicitly, and it lets you vary their interaction independently. 
+
+### When to use
+
+* a set of objects communicate in well-defined but complex ways
+* reusing an object is difficult because it refers to and communicates with many other objects
+* a behavior that's distributed between several classes should be customizable without a lot of subclassing
