+## Run Waku node
+
+Running Waku node is a matter of a correct configuration. To enable Waku and JSON-RPC HTTP interface use:
+```shell script
+{
+  "APIModules": "waku",
+  "HTTPEnabled": true,
+  "HTTPHost": "localhost",
+  "HTTPPort": 8545,
+  "WakuConfig": {
+    "Enabled": true
+  }
+}
+```
+
+This command will start a Waku node using the `eth.prod` fleet:
+```shell script
+$ ./build/bin/statusd -c ./_examples/waku.json
+```
+
+From now on, you can interact with Waku using HTTP interface:
+```shell script
+$ curl -XPOST http://localhost:8545 -H 'Content-type: application/json' -d '{"jsonrpc":"2.0","method":"waku_info","params":[],"id":1}'
+```
+
