+When you have an instance running that Backstage can hook into, first install the plugin into your app:
+
+\`\`\`sh
+$ yarn add @backstage/plugin-lighthouse
+\`\`\`
+
+Then make sure to export the plugin in your app's [\`plugins.ts\`](https://github.com/backstage/backstage/blob/master/packages/app/src/plugins.ts) to enable the plugin:
 
 \`\`\`js
 export { plugin as LighthousePlugin } from '@backstage/plugin-lighthouse';
 \`\`\`
 
-Then, you need to use the \`lighthouseApiRef\` exported from the plugin to initialize the Rest API in
-your [\`apis.ts\`](https://github.com/backstage/backstage/blob/master/packages/app/src/apis.ts).
+Modify your app routes in \`App.tsx\` to include the Router component exported from the plugin, for example:
 
 \`\`\`js
-import { ApiHolder, ApiRegistry } from '@backstage/core';
-import {
-  lighthouseApiRef,
-  LighthouseRestApi,
-} from '@backstage/plugin-lighthouse';
+// At the top imports
+import { Router as LighthouseRouter } from '@backstage/plugin-lighthouse';
 
-const builder = ApiRegistry.builder();
+// Inside App component
+<Routes>
+  // ...
+  <Route path="/lighthouse/*" element={<LighthouseRouter />} />
+  // ...
+</Routes>;
+\`\`\`
 
-export const lighthouseApi =
-  new LighthouseRestApi(/* your service url here! */);
-builder.add(lighthouseApiRef, lighthouseApi);
+Then configure the \`lighthouse-audit-service\` URL in your [\`app-config.yaml\`](https://github.com/backstage/backstage/blob/master/app-config.yaml).
 
-export default builder.build() as ApiHolder;
+\`\`\`yaml
