 To enable it, add the `VueComponentDebug` plugin to your Vue application. This can be done in your main entry file (e.g., `main.js` or `main.ts`):
 
 ```javascript
-import { createApp } from 'vue'
-import VueComponentDebug from 'vue-component-debug'
-import App from './App.vue'
+import { createApp } from 'vue';
+import VueComponentDebug from 'vue-component-debug';

+app.use(VueComponentDebug);
 
-app.mount('#app')

 ```
 
-Comments will only be added in development mode.
+By default, comments will always be outputted while in development mode and removed in production mode. However, you're welcome to override this behavior by passing an `enabled` option to the plugin:

+app.use(VueComponentDebug, { enabled: false });
