+### New Backend System
+
+The Playlist backend plugin has support for the [new backend system](https://backstage.io/docs/backend-system/), here's how you can set that up:
+
+In your `packages/backend/src/index.ts` make the following changes:
+
+```diff
+import { createBackend } from '@backstage/backend-defaults';
+
+const backend = createBackend();
+
+backend.add(import('@backstage/plugin-playlist-backend'));
+// ... other feature additions
+
+backend.start();
+```
