 This repository is the JavaScript client for Node. There is also a **[browser client](https://github.com/sciactive/nymph-client)**.  For more information, you can see the [main Nymph repository](https://github.com/sciactive/nymph).
 
-The Nymph client requires some browser globals that Node doesn't provide, so this client sets up some globals to provide them.
-
-It also sets up Nymph.init to also call PubSub.init with your configs, so you don't need to set up PubSub yourself.
+This package provides fetch and WebSocket ponyfills to Nymph, handles Tilmeld auth tokens, and sets up `Nymph.init` to also call `PubSub.init` with your configs if you provide a `pubsubURL`.
