 #### Custom Matchers API
 
-Matchers should return an object (or a Promise of an object) with two keys. `pass` indicates whether there was a match or not, and `message` provides a function with no arguments that return an error message in case of failure. Thus, when `pass` is false, `message` should return the error message for when `expect(x).yourMatcher()` fails. And when `pass` is true, `message` should return the error message for when `expect(x).not.yourMatcher()` fails.
