+## This is a Work In Progress

+You can track progress on the [project board](https://github.com/status-im/js-waku/projects/1)
+
+## Examples
+
+## Chat app
+
+A node chat app is provided as a working example of the library.
+It is interoperable with the [nim-waku chat app example](https://github.com/status-im/nim-waku/blob/master/examples/v2/chat2.nim).
+To run the chat app:
+
+```shell
+npm install
+npm run chat:app -- --staticNode /ip4/134.209.139.210/tcp/30303/p2p/16Uiu2HAmPLe7Mzm8TsYUubgCAW1aJoeFScxrLj8ppHFivPo97bUZ --listenAddr /ip4/0.0.0.0/tcp/55123
+```
+
+The `--listenAddr` parameter is optional, however [NAT passthrough](https://github.com/status-im/js-waku/issues/12) is not yet supported so you'll need the listen port to be opened to the internet to receive messages from the fleet.
