* Up

* Added mocha.opts file with recursive param

* Replaced chainable with resolvable

* Added SimpleResolvable class

 ## Usage
 ### Create your first resolver using the `chain`, `protect` or `apply` api
 
-#### `chain` api
-
-Create a new resolver chaining the ones in the supplied array. *The order matters from left to right*.
-The last resolver being the one return the final expect value.
+#### `chain`
+Return a resolver that is the sum of the ones in the supplied array.
+*The execution order follows the order from left to right*.
