+# Authentication Navigation Implementation - Setup Guide
+
+## ✅ Implementation Complete!
+
+All authentication navigation components have been created successfully. Follow these steps to get the app running:
+
+## Step 1: Install Dependencies
+
+The following packages need to be installed:
+
+```bash
+cd nftopia-mobile-app
+
+# Using npm
+npm install @react-navigation/native @react-navigation/stack zustand react-native-screens react-native-safe-area-context
+
+# Or using pnpm (if available)
+pnpm install
+```
+
+### If you encounter PowerShell execution policy errors on Windows:
+
+**Option 1: Run as Administrator**
+- Right-click PowerShell → "Run as Administrator"
+- Execute: `Set-ExecutionPolicy RemoteSigned -Scope CurrentUser`
+- Then run the install command
+
+**Option 2: Use cmd instead**
+- Open Command Prompt (cmd)
+- Navigate to the mobile app directory
+- Run: `npm install`
+
+**Option 3: Bypass for single command**
+```powershell
+powershell -ExecutionPolicy Bypass -Command "npm install"
+```
+
+## Step 2: Verify Installation
+
+After installing dependencies, verify everything is set up correctly:
+
+```bash
+# Start the development server
+npm start
+
+# For Android
+npm run android
+
+# For iOS (requires macOS and Xcode)
+npm run ios
+```
+
+## Step 3: Test the Authentication Flow
+
+1. **First Launch**: You should see the splash screen briefly, then the onboarding screen
+2. **Wallet Creation Flow**: 
+   - Tap "Get Started"
+   - Select "Create New Wallet"
+   - Enter and confirm password (min 8 characters)
+   - Tap "Create Wallet"
+3. **Wallet Import Flow**:
+   - From Wallet Selection, select "Import Wallet"
+   - Enter a valid Stellar secret key (starts with 'S')
+   - Enter password for encryption
+   - Tap "Import Wallet"
+4. **Email Authentication Flow**:
+   - From Onboarding, tap "Sign In with Email"
+   - Toggle between Sign In and Sign Up
+   - Enter valid email and password

+### Core Navigation
+- ✅ `navigation/AppNavigator.tsx` - Main conditional router
+- ✅ `navigation/AuthNavigator.tsx` - Auth stack navigator  
+- ✅ `navigation/MainNavigator.tsx` - Main app placeholder
+- ✅ `navigation/index.ts` - Navigation exports
+
+### Auth Screens
+- ✅ `screens/Auth/OnboardingScreen.tsx`
+- ✅ `screens/Auth/WalletSelectionScreen.tsx`
+- ✅ `screens/Auth/WalletCreateScreen.tsx`
+- ✅ `screens/Auth/WalletImportScreen.tsx`
+- ✅ `screens/Auth/EmailLoginScreen.tsx`
+- ✅ `screens/Auth/EmailRegisterScreen.tsx`
+
+### State Management
+- ✅ `stores/authStore.ts` - Zustand auth store
+- ✅ `types/auth.ts` - Type definitions
+
+### Components
+- ✅ `components/SplashScreen.tsx` - Loading screen
+
+### App Entry
+- ✅ `App.tsx` - Updated with navigation container
+
+### Documentation
+- ✅ `NAVIGATION-README.md` - Comprehensive documentation
+- ✅ `__tests__/auth-navigation.test.ts` - Test suite
+
+## 🎯 Key Features Implemented
+
+### 1. Conditional Routing
+- Automatic redirect based on authentication state
+- Splash screen during auth check
+- Persistent login across app restarts
+
+### 2. Navigation Stack
+- Smooth transitions between screens
+- Gesture-based navigation (swipe to go back)
+- Proper back button behavior
+
+### 3. State Management
+- Zustand store for global auth state
+- Secure storage integration
+- Clean state on logout
+
+### 4. Security
+- Password encryption for wallets
+- Secure credential storage
+- Input validation
+
+## 🔧 Configuration
+
+### TypeScript Paths
+
+The following path aliases are configured in `tsconfig.json`:
+
+```json
+{
+  "@/*": "./*",
+  "@/components/*": "components/*",
+  "@/screens/*": "screens/*",
+  "@/navigation/*": "navigation/*",
+  "@/stores/*": "stores/*",
+  "@/types/*": "types/*"
+}
+```
+
+### Package.json Updates
+
+Make sure your `package.json` includes:
+
+```json
+{
+  "dependencies": {
+    "@react-navigation/native": "^7.0.14",
+    "@react-navigation/stack": "^7.1.1",
+    "zustand": "^5.0.2",
+    "react-native-screens": "^4.6.0",
+    "react-native-safe-area-context": "^5.1.0"
+  }
+}
+```
+
+## 🐛 Troubleshooting
+
+### Issue: Module not found errors
+**Solution**: Run `npm install` to install all dependencies
+
+### Issue: Navigation doesn't work
+**Solution**: Ensure all React Navigation dependencies are installed and peer dependencies are satisfied
+
+### Issue: TypeScript errors
+**Solution**: 
+1. Make sure dependencies are installed
+2. Restart TypeScript server in your IDE
+3. Check that tsconfig.json paths are correct
+
+### Issue: App crashes on startup
+**Solution**:
+1. Clear Metro bundler cache: `npm start -- --reset-cache`
+2. Rebuild the app
+3. Check console for error messages
+
+### Issue: SecureStore not working
+**Solution**: Ensure expo-secure-store is installed (it comes with Expo)
+
+## 📱 Next Steps
+
+After getting the navigation working:
+
+1. **Implement Backend Integration**: Connect to actual API endpoints
+2. **Add Biometric Auth**: Implement Face ID/Touch ID
+3. **Enhance Validation**: Add more robust input validation
+4. **Add Loading States**: Show loading indicators during async operations
+5. **Error Handling**: Implement comprehensive error handling
+6. **Analytics**: Add tracking for user flows
+7. **Accessibility**: Ensure all screens are accessible
+
+## 🤝 Testing Checklist
+
+Before considering implementation complete, test:
+
+- [ ] Splash screen appears on app launch
+- [ ] Onboarding screen displays correctly
+- [ ] Navigation to WalletSelection works
+- [ ] Wallet creation flow completes successfully
+- [ ] Wallet import validates secret keys
+- [ ] Email login/register forms validate inputs
+- [ ] Back navigation works as expected
+- [ ] Auth state persists after app restart
+- [ ] Logout clears all user data
+- [ ] No console errors or warnings
+
+## 📚 Additional Resources
+

+
+The implementation follows best practices for:
+- React Native navigation patterns
+- State management with Zustand
+- Security with encrypted storage
+- User experience with smooth transitions
+- Code organization and maintainability
