+# Cloud Recording
+
+![cloud](./assets/cloud.png)
+
+To save `recordings` on a different `server` or `cloud service` copy this `cloud folder` to the desired server.
+
+## Quick Start
+
+```bash
+# Install dependencies
+npm install
+
+# Start the server
+npm start
+```
+
+## Edit config.js
+
+In the MiroTalk SFU `app/src/config.js` file, change the endpoint to send recording chunks:
+
+```js
+recording: {
+	endpoint: 'http://localhost:8080', // Change it with your Server endpoint
+	dir: 'rec',
+	enabled: true,
+},
+```
