+#### Add custom WebSocket handlers
+
+You can create custom WebSocket servers (like [ws](https://github.com/websockets/ws) for example) using `registerWebSocketRoute`:
+
+```js
+function register ({
+  registerWebSocketRoute,
+  peertubeHelpers
+}) {
+  const wss = new WebSocketServer({ noServer: true })
+
+  wss.on('connection', function connection(ws) {
+    peertubeHelpers.logger.info('WebSocket connected!')
+
+    setInterval(() => {
+      ws.send('WebSocket message sent by server');
+    }, 1000)
+  })
+
+  registerWebSocketRoute({
+    route: '/my-websocket-route',
+
+    handler: (request, socket, head) => {
+      wss.handleUpgrade(request, socket, head, ws => {
+        wss.emit('connection', ws, request)
+      })
+    }
+  })
+}
+```

+The `my-websocket-route` route can be accessed using:
+ * `/plugins/:pluginName/:pluginVersion/ws/my-websocket-route`
+ * Or `/plugins/:pluginName/ws/my-websocket-route`

 #### Add external auth methods
 
 If you want to add a classic username/email and password auth method (like [LDAP](https://framagit.org/framasoft/peertube/official-plugins/-/tree/master/peertube-plugin-auth-ldap) for example):
