+# Firebase Google Sign-In setup
+
+## Quick setup (Ubuntu CLI)
+
+Reload your shell after the first run (or open a new terminal):
+
+```bash
+source ~/.bashrc
+```
+
+One-shot setup (installs tools, logs in, configures FlutterFire, registers debug SHA-1):
+
+```bash
+cd ~/cyberhybridhub.com
+chmod +x scripts/setup-firebase-google-auth.sh scripts/get-android-sha.sh
+
+# Optional: set your Firebase project id to skip the interactive picker
+export FIREBASE_PROJECT_ID=your-firebase-project-id
+
+./scripts/setup-firebase-google-auth.sh
+```
+
+Or run step by step:
+
+```bash
+# 1. Tools (if not already installed)
+npm install -g firebase-tools
+dart pub global activate flutterfire_cli
+
+# 2. Login (FlutterFire uses the Firebase CLI session)
+firebase login
+
+# 3. Register apps + download config (android, ios, web)
+cd ~/cyberhybridhub.com
+flutterfire configure \
+  --project=YOUR_FIREBASE_PROJECT_ID \
+  --platforms=android,ios,web \
+  --android-package-name=com.cyberhybridhub.cyberhybridhub \
+  --ios-bundle-id=com.cyberhybridhub.cyberhybridhub \
+  --out=lib/firebase_options.dart
+
+# 4. Debug SHA-1 (Android Google Sign-In)
+./scripts/get-android-sha.sh
+firebase apps:list --project=YOUR_FIREBASE_PROJECT_ID
+firebase apps:android:sha:create ANDROID_APP_ID YOUR_SHA1 --project=YOUR_FIREBASE_PROJECT_ID
+flutterfire configure --project=YOUR_FIREBASE_PROJECT_ID --platforms=android,ios,web --yes
+
+# 5. Enable Google provider (browser — required)
+#    https://console.firebase.google.com/ → Authentication → Sign-in method → Google → Enable
+
+# 6. Run
+flutter pub get && flutter run
+```
+
+`~/.bashrc` includes `~/.pub-cache/bin` (for `flutterfire`) and `CYBERHYBRIDHUB_ROOT`.
+
+---
+
+## Linux desktop development (`flutter run -d linux`)
+
+Official FlutterFire does not register native plugins on Linux, so this app uses:
+
+- `google_sign_in_all_platforms` (system browser OAuth)
+- Firebase Auth REST (`signInWithIdp`) with web API key from `lib/firebase_options.dart`
+
+### One-time Linux OAuth setup
+
+1. [Google Cloud Console](https://console.cloud.google.com/) → project **cyberhybridhub** → **APIs & Services** → **Credentials**
+2. Open your **Web application** OAuth 2.0 client (or create one)
+3. Add authorized redirect URI: `http://127.0.0.1`
+4. Copy **Client ID** and **Client secret** into `lib/config/auth_config.dart`:
+
+```dart
+const String? googleWebOAuthClientId = 'YOUR_CLIENT_ID.apps.googleusercontent.com';
+const String? googleOAuthDesktopClientSecret = 'YOUR_CLIENT_SECRET';
+```
+
+### Web browser (`flutter run -d web-server` or Chrome)
+
+Uses the same `googleWebOAuthClientId`. In Google Cloud, on that Web OAuth client, add **Authorized JavaScript origins**:
+
+- `http://localhost`
+- `http://127.0.0.1`
+
+(Uncomment the `google-signin-client_id` meta tag in `web/index.html` only if you prefer HTML config over Dart.)
+
+5. Enable Google sign-in in Firebase Console (if not already)
+6. Run:
+
+```bash
+flutter run -d linux
+```
+
+---
+
+## Manual checklist
+
+Complete these steps to replace placeholder config files and enable Google authentication.
+
+App identifiers used by this project:
+
+| Platform | Identifier |
+|----------|------------|
+| Android package | `com.cyberhybridhub.cyberhybridhub` |
+| iOS bundle ID | `com.cyberhybridhub.cyberhybridhub` |
+
+---
+
+## 1. Create a Firebase project
+
+- [ ] Open [Firebase Console](https://console.firebase.google.com/).
+- [ ] Create a project (or select an existing one).
+- [ ] Enable **Google Analytics** only if you need it (optional for auth).
+
+---
+
+## 2. Register the Flutter app in Firebase
+
+- [ ] In Firebase Console → **Project settings** → **Your apps**, add:
+  - [ ] **Android** app with package name `com.cyberhybridhub.cyberhybridhub`
+  - [ ] **iOS** app with bundle ID `com.cyberhybridhub.cyberhybridhub`
+  - [ ] **Web** app (required for the web OAuth client used by Google Sign-In on mobile)
+- [ ] Download config files when prompted:
+  - [ ] `google-services.json` → replace `android/app/google-services.json`
+  - [ ] `GoogleService-Info.plist` → replace `ios/Runner/GoogleService-Info.plist`
+
+### Recommended: FlutterFire CLI
+
+```bash
+dart pub global activate flutterfire_cli
+flutterfire configure
+```
+
+This regenerates `lib/firebase_options.dart` and downloads the platform config files.
+
+---
+
+## 3. Enable Google sign-in in Firebase
+
+- [ ] Firebase Console → **Build** → **Authentication** → **Sign-in method**
+- [ ] Enable **Google**
+- [ ] Set a support email and save
+
+---
+
+## 4. Google Cloud Console (OAuth & credentials)
+
+Firebase links to a Google Cloud project. Open it from Firebase → **Project settings** → **General** → **Google Cloud Platform resource location** → link to GCP, or go to [Google Cloud Console](https://console.cloud.google.com/) and select the same project.
+
+### 4.1 OAuth consent screen
+
+- [ ] **APIs & Services** → **OAuth consent screen**
+- [ ] Choose **External** (or Internal for Workspace-only)
+- [ ] Fill app name, user support email, developer contact
+- [ ] Add scopes if needed (default `email`, `profile`, `openid` are usually enough)
+- [ ] Add test users while the app is in **Testing** mode
+
+### 4.2 OAuth 2.0 Client IDs
+
+- [ ] **APIs & Services** → **Credentials**
+- [ ] Confirm these clients exist (Firebase often creates them automatically):
+
+| Client type | Purpose |
+|-------------|---------|
+| **Web application** | `serverClientId` / ID token for Firebase Auth on Android |
+| **Android** | Package name + SHA-1 certificate fingerprints |
+| **iOS** | Bundle ID |
+
+#### Android SHA-1 fingerprints
+
+Debug keystore (local development):
+
+```bash
+keytool -list -v -keystore ~/.android/debug.keystore -alias androiddebugkey -storepass android -keypass android
+```
+
+Release keystore (production):
+
+```bash
+keytool -list -v -keystore /path/to/your-release.keystore -alias your-alias
+```
+
+- [ ] Add **SHA-1** (and **SHA-256** if offered) to the Android OAuth client in Google Cloud Console
+- [ ] Re-download `google-services.json` after adding fingerprints
+
+#### iOS URL scheme
+
+- [ ] Open `ios/Runner/GoogleService-Info.plist` and copy `REVERSED_CLIENT_ID`
+- [ ] In Xcode (or `ios/Runner/Info.plist`), add a URL type:
+  - **URL Schemes**: value of `REVERSED_CLIENT_ID`
+  - Example: `com.googleusercontent.apps.123456789-abcdef`
+
+---
+
+## 5. App code configuration
+
+- [ ] Replace placeholders in `lib/firebase_options.dart` (or run `flutterfire configure`)
+- [ ] If sign-in fails on Android with a `serverClientId` error, set the Web client ID in `lib/config/auth_config.dart`:
+
+```dart
+const String? googleSignInServerClientId = 'YOUR_WEB_CLIENT_ID.apps.googleusercontent.com';
+```
+
+Find the Web client ID in Firebase → Project settings → Your apps → Web app, or in `google-services.json` under `oauth_client` with `"client_type": 3`.
+
+---
+
+## 6. Verify
+
+```bash
+flutter pub get
+flutter run
+```
+
+- [ ] Tap **Continue with Google** on the login screen
+- [ ] Complete Google account selection
+- [ ] Confirm the home screen shows your name and email
+- [ ] Sign out and sign in again
+
+---
+
+## Troubleshooting
+
+| Symptom | Likely fix |
+|---------|------------|
+| `clientConfigurationError` | Wrong package/bundle ID, missing SHA-1, or invalid `google-services.json` |
+| Sign-in cancels immediately after account pick | Missing web OAuth client in `google-services.json` or wrong SHA-1 |
+| `serverClientId must be provided on Android` | Add Web app in Firebase, re-download `google-services.json`, or set `googleSignInServerClientId` |
+| iOS sign-in fails after Google UI | Add `REVERSED_CLIENT_ID` URL scheme to `Info.plist` |
+| `REPLACE_ME` / invalid API key at runtime | Run `flutterfire configure` or paste real values from Firebase |

+# Launch Screen Assets
+
+You can customize the launch screen with your own desired assets by replacing the image files in this directory.
+
+You can also do it by opening your Flutter project's Xcode project with `open ios/Runner.xcworkspace`, selecting `Runner/Assets.xcassets` in the Project Navigator and dropping in the desired images.
