+## New Backend System
+
+The code coverage 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';
++ import { codeCoveragePlugin } from '@backstage/plugin-code-coverage-backend';
+  const backend = createBackend();
+  // ... other feature additions
++ backend.add(codeCoveragePlugin());
+  backend.start();
+```
+
+Alternatively, you can actually remove the import line above, and do this instead.
+
+```diff
+  backend.add(explorePlugin());
++ backend.add(import('@backstage/plugin-explore-backend'));
+
+```
+
 ## Configuring your entity
 
 In order to use this plugin, you must set the `backstage.io/code-coverage` annotation.
