 ## Usage
 
 This module provides a function to wrap your components in a finite state machine.
+This gives your component to additional props: `status` and `transition`.
+
+The status is the current status of the component.
+Transition is a function that takes as first argument `this`, and as second an object with 
+`type` key that contains the `Action`.
