 # Multiple Callback Resolver

 This project contains a simple class that allows you to instantiate callback functions
 and then execute a final callback when all of the generated callbacks complete. This
 is especially useful in testing that a set of events is emitted in a test case or in
-fanning out a set of work and then 
+fanning out a set of work and running some code after all of a set of callbacks has
+been invoked.
 
 Let's say you have a class called `Something` and it emits 3 events when
 when the `run()` method is processed.
