 When the `defaultBootstrap` parameter is set to `true`, your node will be bootstrapped using the [default bootstrap method](/guides/js-waku/configure-discovery#default-bootstrap-method). Have a look at the [Bootstrap Nodes and Discover Peers](/guides/js-waku/configure-discovery) guide to learn more methods to bootstrap nodes.

-A node needs to know how to route messages. In order to do that you can use standard pubsub topic (`/waku/2/default-waku/proto`). If your project uses a different pubsub topic, you can configure this by providing a set of [content topics](/learn/concepts/content-topics) for the node to use with the `contentTopics` parameter or by using the `ShardInfo` parameter:
+A node needs to know how to route messages. By default, it will use The Waku Network configuration (`{ clusterId: 1, shards: [0,1,2,3,4,5,6,7] }`). If your project uses a different network configuration, you can configure this using the `networkConfig` parameter:

 :::tip Congratulations!
 You have successfully sent and received messages over the Waku Network using the `Light Push` and `Filter` protocols. Have a look at the [light-js](https://github.com/waku-org/js-waku-examples/tree/master/examples/light-js) and [light-chat](https://github.com/waku-org/js-waku-examples/tree/master/examples/light-chat) examples for working demos.
