 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. By default, it will use The Waku Network configuration (`{ clusterId: 1, shards: [0,1,2,3,4,5,6,7] }`). For most applications, it's recommended to use autosharding:
+
+```js
+// Create node with auto sharding (recommended)
+const node = await createLightNode({
+  defaultBootstrap: true,
+  networkConfig: {
+    clusterId: 1,
+    contentTopics: ["/my-app/1/notifications/proto"],
+  },
+});
+```
+
+### Alternative network configuration
+
+If your project requires a specific network configuration, you can use static sharding:
+
+```js
+// Create node with static sharding
+const node = await createLightNode({
+  defaultBootstrap: true,
+  networkConfig: {
+    clusterId: 1,
+    shards: [0, 1, 2, 3],
+  },
+});
+```

 In this example, users send and receive messages on a shared content topic. However, real applications may have users broadcasting messages while others listen or only have 1:1 exchanges. Waku supports all these use cases.
