+### Add custom renderer
+
+You can add your custom renderer from the CLI using `--custom-renderer` option:
+
+```js
+// renderer.js
+module.exports = (req, res) => {
+    res.jsonp({
+        version: "v1",
+        statusCode: 200,
+        isError: false,
+        message: "The Request successful.",
+        result: res.locals.data,
+    })
+}
+```

+```bash
+json-server db.json --custom-renderer ./renderer.js
