+- Complete navigation structure connecting all main modules
+- Bottom navigation bar with 5 main screens: Home, Immich, Nostr Events, Session, Settings
+- Route guards requiring authentication for protected screens
+- Placeholder screens for all modules ready for custom UI implementation
+- Modular navigation architecture with testable components
+- Comprehensive UI tests for navigation and route guards
 
 ## Quick Start
 
@@ -141,24 +105,96 @@ Service for managing user sessions, login, logout, and session isolation. Provid
 
 **Usage:** Initialize `SessionService` with `LocalStorageService` and optional `SyncEngine`. Call `login()` to start a session, `logout()` to end it, and `switchSession()` to change users.
 
+## Firebase Layer
+
+Optional Firebase integration providing cloud sync, storage, authentication, push notifications, and analytics. Fully modular - can be enabled or disabled without affecting offline-first functionality. Integrates with local storage and session management to maintain offline-first behavior.
+
+**Files:**
+- `lib/data/firebase/firebase_service.dart` - Main Firebase service
+- `lib/data/firebase/models/firebase_config.dart` - Firebase configuration model
+- `test/data/firebase/firebase_service_test.dart` - Unit tests
+
+**Key Methods:** `initialize()`, `loginWithEmailPassword()`, `logout()`, `syncItemsToFirestore()`, `syncItemsFromFirestore()`, `uploadFile()`, `getFcmToken()`, `logEvent()`
+
+**Features:** Firestore cloud sync, Firebase Storage for media, Firebase Auth for authentication, Firebase Cloud Messaging for push notifications, Firebase Analytics for analytics, all optional and modular
+
+**Usage:** Create `FirebaseService` with `FirebaseConfig` (disabled by default). Pass to `SessionService` for automatic sync on login/logout. Initialize Firebase with `initialize()` before use. All services gracefully handle being disabled.
+
+**Note:** Firebase requires actual Firebase project setup with `google-services.json` (Android) and `GoogleService-Info.plist` (iOS) configuration files. The service handles missing configuration gracefully and maintains offline-first behavior.
+
+## Navigation & UI Scaffold
+
+Complete navigation structure connecting all main modules with bottom navigation bar. Includes route guards for protected screens and placeholder screens ready for custom UI implementation.
+
+**Files:**
+- `lib/ui/navigation/main_navigation_scaffold.dart` - Main navigation scaffold with bottom nav
+- `lib/ui/navigation/app_router.dart` - Router with route guards and route generation
+- `lib/ui/home/home_screen.dart` - Home screen (local storage items)
+- `lib/ui/immich/immich_screen.dart` - Immich media screen (placeholder)
+- `lib/ui/nostr_events/nostr_events_screen.dart` - Nostr events screen (placeholder)
+- `lib/ui/session/session_screen.dart` - Session management (login/logout)
+- `lib/ui/settings/settings_screen.dart` - Settings screen
+- `test/ui/navigation/main_navigation_scaffold_test.dart` - Navigation tests
+
+**Navigation Structure:**
+- **Home** - Local storage and cached content (no auth required)
+- **Immich** - Immich media integration (requires login)
+- **Nostr Events** - Nostr events display (requires login)
+- **Session** - User login/logout (no auth required)
+- **Settings** - App settings and Relay Management access (no auth required)
+
+**Route Guards:** Immich and Nostr Events screens require authentication. Unauthenticated users see a login prompt with option to navigate to Session screen.
+
+**Usage:** The app automatically uses `MainNavigationScaffold` after initialization. All services are passed to the scaffold for dependency injection. Customize placeholder screens by editing the respective screen files in `lib/ui/`.
+
+**Running UI Tests:**
+```bash
+flutter test test/ui/navigation/main_navigation_scaffold_test.dart
+```
+
 ## Configuration
 
 **Configuration uses `.env` files for sensitive values (API keys, URLs) with fallback defaults in `lib/config/config_loader.dart`.**
 
 ### Setup .env File

    ```bash
    cp .env.example .env

-   - `IMMICH_API_KEY_PROD` - Your production Immich API key
-   - `NOSTR_RELAYS_DEV` - Comma-separated Nostr relay URLs for dev
-   - `NOSTR_RELAYS_PROD` - Comma-separated Nostr relay URLs for prod
-   - Other configuration values as needed
+4. Edit `.env` with your actual configuration values.
 
 **Important:** The `.env` file is in `.gitignore` and should never be committed to version control. Only commit `.env.example` as a template.

+## App Name Configuration
+
+# 1. Set APP_NAME in your .env file
+# 2. Run the script
+./scripts/set_app_name.sh
+
+To make this easier, you can use the provided script that reads `APP_NAME` from `.env` and automatically updates all platform files:
+
+```bash
+# Make sure APP_NAME is set in your .env file first
+./scripts/set_app_name.sh
+```
+
+This script will:
+1. Read `APP_NAME` from your `.env` file
+2. Update `android/app/src/main/AndroidManifest.xml`
+3. Update `macos/Runner/Configs/AppInfo.xcconfig`
+
+**Manual Setup:** If you prefer to set it manually, just update the files listed above directly.
+
+## App Icon Configuration
+
+App icons are platform-specific and must be placed in the correct directories with the correct formats.
+
+### Android Icons
+
+**Location:** `android/app/src/main/res/mipmap-*/`
+
+**Format:** PNG files
+
+**Required Sizes:**
+- `mipmap-mdpi/ic_launcher.png` - 48x48 px
+- `mipmap-hdpi/ic_launcher.png` - 72x72 px
+- `mipmap-xhdpi/ic_launcher.png` - 96x96 px
+- `mipmap-xxhdpi/ic_launcher.png` - 144x144 px
+- `mipmap-xxxhdpi/ic_launcher.png` - 192x192 px
+
+**Instructions:**
+1. Create your app icon as a square image (recommended: 1024x1024 px source)
+2. Generate all required sizes using an icon generator tool (e.g., [App Icon Generator](https://www.appicon.co/))
+3. Replace the existing `ic_launcher.png` files in each `mipmap-*` directory
+4. The icon is referenced in `AndroidManifest.xml` as `@mipmap/ic_launcher`
+
+**Best Practices:**
+- Use PNG format (no transparency for launcher icons on some Android versions)
+- Keep icon simple and recognizable at small sizes
+- Follow Material Design guidelines for Android icons
+- Ensure icon works on both light and dark backgrounds
+
+### macOS Icons
+
+**Location:** `macos/Runner/Assets.xcassets/AppIcon.appiconset/`
+
+**Format:** PNG files
+
+**Required Sizes:**
+- `app_icon_16.png` - 16x16 px
+- `app_icon_32.png` - 32x32 px
+- `app_icon_64.png` - 64x64 px
+- `app_icon_128.png` - 128x128 px
+- `app_icon_256.png` - 256x256 px
+- `app_icon_512.png` - 512x512 px
+- `app_icon_1024.png` - 1024x1024 px
+
+**Instructions:**
+1. Create your app icon as a square image (recommended: 1024x1024 px source)
+2. Generate all required sizes
+3. Replace the existing PNG files in `AppIcon.appiconset/` directory
+4. The `Contents.json` file defines which sizes map to which files - update if needed
+
+**Best Practices:**
+- Use PNG format
+- macOS icons can have transparency
+- Follow macOS Human Interface Guidelines
+- Icon should be recognizable at 16x16 size
+
+### iOS Icons (if adding iOS support)
+
+**Location:** `ios/Runner/Assets.xcassets/AppIcon.appiconset/`
+
+**Format:** PNG files (no transparency for some sizes)
+
+**Required Sizes:** iOS requires many sizes. Use Xcode's App Icon set or a tool like [App Icon Generator](https://www.appicon.co/) to generate all required sizes automatically.
+
+**Best Practices:**
+- Use PNG format
+- Some sizes require no transparency (check iOS guidelines)
+- Follow iOS Human Interface Guidelines
+- Generate all sizes from a 1024x1024 px source
+
+### Icon Generation Tools
+
+Recommended tools for generating all required icon sizes:
+- [AppIcon.co](https://www.appicon.co/) - Online tool, supports multiple platforms
+- [IconKitchen](https://icon.kitchen/) - Google's icon generator
+- [MakeAppIcon](https://makeappicon.com/) - Generates all sizes from one image
+- Xcode (for macOS/iOS) - Built-in asset catalog editor
+
+### Quick Setup
+
+1. **Prepare your icon:** Create a 1024x1024 px square PNG image
+2. **Generate sizes:** Use one of the tools above to generate all required sizes
+3. **Replace files:** Copy generated icons to the appropriate directories
+4. **Test:** Run the app and verify icons appear correctly
