-[co] allows you to use generators to manage async flow.

 ### Running generators
 
-A generator can `yield` a thunk or promise. Using `co()` will immediately invoke the block inside it.

 ```js
 co(function * () {
   yield Promise.resolve(true)
 }).then(...)
 ```

+A generator can `yield` a thunk or promise. Using `co()` will immediately invoke the block inside it.
 
-Use `co.wrap()`. Most of the time, you'll be using co.wrap.
