+# NPM LibP2P Relay Daemon
+
+This utility downloads and runs the [V2](https://github.com/libp2p/specs/blob/master/relay/circuit-v2.md) of the [libp2p relay daemon](https://github.com/libp2p/go-libp2p-relay-daemon).
+
+## Usage
+
+First, create a config.json file.  
+
+```shell
+touch config.json
+```
+
+An example of a config.json file:
+
+```json
+{
+  "RelayV1": {
+    "Enabled": false
+  },
+  "RelayV2": {
+    "Enabled": true
+  },
+  "Network": {
+    "ListenAddrs": ["/ip4/127.0.0.1/tcp/24222/ws"],
+    "AnnounceAddrs": ["/ip4/127.0.0.1/tcp/24222/ws"]
+  },
+  "Daemon": {
+    "PprofPort": -1
+  }
+}
+```
+
+Now let's run the libp2p relay deamon:
+
+```js
+const { run } =  require('npm-libp2p-relay-daemon')
+const os = require('os')
+const path = require('path')
+
+const configPath = 'config.json'
+const identityPath = path.join(os.tmpdir(), `relayd_v2-${Math.random()}.identity`)
+
+run(configPath, identityPath)
+```
