+#### Add custom routes
+
+You can create custom routes using an [express Router](https://expressjs.com/en/4x/api.html#router) for your plugin:
+
+```js
+const router = getRouter()
+router.get('/ping', (req, res) => res.json({ message: 'pong' }))
+```
+
+The `ping` route can be accessed using:
+ * `/plugins/:pluginName/:pluginVersion/router/ping`
+ * Or `/plugins/:pluginName/router/ping`
+
+
