+### Using Fake Generated Messages for UI Development
+
+If you're working on the UI and need to see how it interacts with messages, you have the option to enable the generation of fake messages. You can set the `VITE_USE_DUMMY_DATA` environment variable to `"true"` either by exporting it in your terminal or by adding it to your `src/.env` file:
+
+**Setting in the `src/.env` file:**
+
+```env
+VITE_USE_DUMMY_DATA=true
+```
+
+Once this flag is set to `"true"`, the app will switch to using the `useMessageListenerDev` hook instead of the `useMessageListenerProd` hook. This will generate fake messages at regular intervals, allowing you to test the UI without requiring a backend service for messages.
