+# Nwaku Service Node
+
+JS-Waku nodes join the Waku network by connecting to service nodes using secure websocket.
+
+[Nwaku (prev. nim-waku)](https://github.com/status-im/nim-waku/tree/master/waku/v2)
+is the reference implementation of the Waku v2 protocol and can be used as a service node.
+
+When using [`{ bootstrap: { default: true } }`](https://js-waku.wakuconnect.dev/interfaces/discovery.BootstrapOptions.html#default),
+the js-waku node connects to a fleet of nwaku nodes operated by Status.
+
+It is also possible to deploy your own nwaku node by following [these instructions](https://github.com/status-im/nim-waku/tree/master/waku/v2#enabling-websocket).
+Be sure to setup your nwaku node with a valid SSL certificate or js-waku nodes may fail silently to connect to it.
+
+{{< hint info >}}
+We are making it easier for operators to run their own nodes,
+this is effort is tracked with [status-im/nim-waku#828](https://github.com/status-im/nim-waku/issues/828).
+{{< /hint >}}
+
+You may wish to connect your nwaku node to the rest of the fleet.
+This can be done with the `--staticnode` or `--dns-discovery-url`.
+For example:
+
+```sh
+`wakunode2 \
+  --dns-discovery=true \
+  --dns-discovery-url=enrtree://ANTL4SLG2COUILKAPE7EF2BYNL2SHSHVCHLRD5J7ZJLN5R3PRJD2Y@prod.waku.nodes.status.im
+```
+
+You can then use [`bootstrap.peers`](https://js-waku.wakuconnect.dev/interfaces/discovery.BootstrapOptions.html#peers)
+to pass the multiaddr of your node.
+
+For example (replace the multiaddr with your node's).
+
+```js
+import { Waku } from "js-waku";
+
+const waku = await Waku.create({
+  bootstrap: {
+    peers: [
+      "/dns4/node-01.ac-cn-hongkong-c.wakuv2.test.statusim.net/tcp/443/wss/p2p/16Uiu2HAkvWiyFsgRhuJEb9JfjYxEkoHLgnUQmr1N5mKWnYjxYRVm",
+    ],
+  },
+});
+```
