 A modular, offline-first Flutter boilerplate for apps that store, sync, and share media and metadata across centralized (Immich, Firebase) and decentralized (Nostr) systems.
 
-## Phase 8 - Navigation & UI Scaffold
+## Navigation & UI Scaffold
+
+The app uses a custom bottom navigation bar with 4 main tabs and a centered Add Recipe button:
+
+### Main Navigation Tabs
+
+1. **Home** (`lib/ui/home/home_screen.dart`) - Displays local storage items and cached content
+2. **Recipes** (`lib/ui/recipes/recipes_screen.dart`) - Recipe collection (ready for LocalStorageService integration)
+3. **Favourites** (`lib/ui/favourites/favourites_screen.dart`) - Favorite recipes
+4. **User/Session** (`lib/ui/session/session_screen.dart`) - User session management and login
+
+### Add Recipe Button
+
+- **Add Recipe** - Centered button in the bottom navigation bar
+- Opens full-screen Add Recipe form (`lib/ui/add_recipe/add_recipe_screen.dart`)
+- Positioned in the center of the bottom navigation bar (between Recipes and Favourites)
+- Ready for ImmichService integration for image uploads
+
+### Settings & Relay Management
+
+- **Settings Icon** (cog) - Appears in the top-right AppBar of all main screens
+- Tapping it navigates to **Relay Management** screen (`lib/ui/relay_management/`)
+- Accessible from any screen for global relay configuration
+
+### Navigation Architecture
+
+- **MainNavigationScaffold** (`lib/ui/navigation/main_navigation_scaffold.dart`) - Main app shell with bottom nav
+- **AppRouter** (`lib/ui/navigation/app_router.dart`) - Named route management for full-screen navigation
+- **PrimaryAppBar** (`lib/ui/shared/primary_app_bar.dart`) - Shared AppBar widget with settings icon
+- Uses `IndexedStack` for tab navigation (preserves state)
+- Uses `MaterialPageRoute` for full-screen navigation (Add Recipe, Relay Management)
+
+### Screen Structure

+```
+
+### Testing
+
+Run navigation tests:
+```bash
+flutter test test/ui/navigation/main_navigation_scaffold_test.dart
+```
 
-- 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
+Tests verify:
+- Bottom navigation bar displays correctly
+- Tab switching works
+- Add Recipe button (centered in bottom nav) opens Add Recipe screen
+- Settings icon appears in all AppBars
+- Settings icon navigates to Relay Management
