 ## Unhandled Rejections
 
-In node lie emits `unhandledRejection` events when promises are not handled in
-line with how [iojs does so](https://iojs.org/api/process.html#process_event_unhandledrejection)

+In Node.js, lie emits an `unhandledRejection` event when a rejected promise isn't caught, in line with [how io.js does it](https://iojs.org/api/process.html#process_event_unhandledrejection). This allows it to act as a promise shim in both Node.js and the browser.
