-# Firebase Configuration Required
-
-## ⚠️ IMPORTANT: Replace google-services.json
-
-The current `google-services.json` file is a **PLACEHOLDER** and will **NOT** work.
-
-### Steps to get your real google-services.json:
-
-1. Follow the instructions in `/FIREBASE_SETUP.md` in the project root
-2. Download the real `google-services.json` from Firebase Console
-3. Replace the file in this directory: `android/app/google-services.json`
-
-### Quick Link:
-[Firebase Console](https://console.firebase.google.com/)
-
-### Package Name (must match):
-```
-com.github.mystiatech.sage
-```
-
-Without the real Firebase configuration file, household sharing will not work across devices!
