+This library is an abstraction of [`react-tree-walker`](https://github.com/ctrlplusb/react-tree-walker), that allows you to attach an `asyncBootstrap` method to your React "class" components.
 
-Within the `asyncBootstrap` you can do any work/bootstrapping that you like and then return a `Promise` that should resolve to either `true` (which indicates back to the bootstrapping process that it should continue down the current branch of your application in order to locate and resolve any nested `asyncBootstrap` instances), or `false` (which indicates that traversal of the current branch of your application can stop).
+Within the `asyncBootstrap` you can do any asynchronous work you like (e.g. fetching data) that you like, returning a `Promise` to indicate when the asynchronous work has completed.
 
 ## Naive Example
 
 ```jsx
 import asyncBootstrapper from 'react-async-bootstrapper'
