-# Mobile App Sync Testing Guide
-
-## Overview
-This guide helps you test the bi-directional synchronization between the Trackeep mobile app and web dashboard.
-
-## Prerequisites
-
-1. **Backend Server**: Ensure your Trackeep backend is running
-2. **Web Dashboard**: Access the web dashboard at `http://localhost:3000` (or your configured URL)
-3. **Mobile App**: Run the React Native app using:
-   ```bash
-   npm start
-   npm run android  # or npm run ios
-   ```
-
-## First Launch Setup
-
-1. **Server Configuration**: On first launch, the mobile app will show the server setup screen:
-   - Enter your backend URL (e.g., `http://localhost:8080`)
-   - Enter your credentials
-   - Test connection before completing setup
-
-2. **Authentication**: After setup, you'll be redirected to login with your existing credentials
-
-## Testing Real-Time Sync
-
-### Test 1: Create Content on Mobile, Verify on Web
-
-1. **On Mobile App**:
-   - Open the Dashboard
-   - Tap the FAB (+) button
-   - Create a new task, bookmark, or note
-   - Verify it appears in the mobile dashboard
-
-2. **On Web Dashboard**:
-   - Navigate to the corresponding section (Tasks, Bookmarks, or Notes)
-   - The new item should appear within seconds (if WebSocket is connected)
-   - If not, refresh the page to see the synced item
-
-### Test 2: Create Content on Web, Verify on Mobile
-
-1. **On Web Dashboard**:
-   - Create a new task, bookmark, or note
-   - Save the item
-
-2. **On Mobile App**:
-   - The item should appear automatically if real-time sync is working
-   - Pull to refresh on the dashboard to force sync
-   - Check the specific section to verify the item appears
-
-### Test 3: Offline Mode Testing
-
-1. **Enable Offline Mode**:
-   - Turn off internet connection on your mobile device
-   - The app should show "🔴 Offline" status
-
-2. **Create Content Offline**:
-   - Create several tasks, bookmarks, or notes
-   - Notice the pending changes counter increases
-
-3. **Restore Connection**:
-   - Turn internet back on
-   - App should show "🟢 Connected" and auto-sync
-   - Verify items appear on web dashboard
-
-### Test 4: Conflict Resolution
-
-1. **Simulate Conflict**:
-   - Create the same item on both mobile and web while offline
-   - Bring both online simultaneously
-   - Verify how conflicts are resolved (last write wins or merge)
-
-## Key Features to Test
-
-### Real-Time Updates
-- ✅ WebSocket connection status
-- ✅ Instant updates across devices
-- ✅ Connection recovery after disconnection
-
-### Offline Support
-- ✅ Offline data persistence
-- ✅ Pending changes tracking
-- ✅ Automatic sync when online
-- ✅ Manual sync button
-
-### Data Integrity
-- ✅ All data types sync correctly (tasks, bookmarks, notes)
-- ✅ Timestamps preserved
-- ✅ User associations maintained
-- ✅ Tags and metadata sync
-
-## Troubleshooting
-
-### Common Issues
-
-1. **WebSocket Connection Failed**:
-   - Check if backend WebSocket endpoint is accessible
-   - Verify firewall settings
-   - Check browser console for WebSocket errors
-
-2. **Sync Not Working**:
-   - Verify server URL in mobile app settings
-   - Check authentication tokens
-   - Review backend logs for sync errors
-
-3. **Offline Mode Not Detected**:
-   - Check network permissions on mobile device
-   - Verify NetInfo plugin is working
-   - Test with airplane mode
-
-### Debug Tools
-
-1. **Mobile App Debugging**:
-   ```bash
-   # Enable debug mode
-   npx react-native log-android
-   npx react-native log-ios
-   ```
-
-2. **Backend Logs**:
-   - Monitor sync endpoint logs
-   - Check WebSocket connection logs
-   - Review database transaction logs
-
-3. **Browser Console**:
-   - Monitor WebSocket connections
-   - Check for real-time update events
-   - Verify API responses
-
-## Performance Testing
-
-### Test Scenarios
-
-1. **Large Dataset Sync**:
-   - Create 100+ items on one device
-   - Measure sync time to other device
-   - Verify no data loss
-
-2. **Concurrent Updates**:
-   - Multiple users updating same data
-   - Test conflict resolution
-   - Verify data consistency
-
-3. **Network Conditions**:
-   - Test on slow networks (2G/3G)
-   - Test with intermittent connectivity
-   - Verify sync resilience
-
-## Expected Results
-
-### Successful Sync Indicators
-
-1. **Mobile App**:
-   - Status shows "🟢 Connected"
-   - Last sync time updates
-   - No pending changes counter
-   - Real-time updates received
-
-2. **Web Dashboard**:
-   - New items appear without refresh
-   - WebSocket connection established
-   - No sync errors in console
-
-### Performance Benchmarks
-
-- **Small items** (< 1KB): Should sync within 1-2 seconds
-- **Large items** (> 100KB): Should sync within 5-10 seconds
-- **Batch sync** (50+ items): Should complete within 30 seconds
-
-## Automated Testing
-
-For comprehensive testing, consider implementing:
-
-1. **Unit Tests**:
-   - Sync logic validation
-   - Offline queue management
-   - Conflict resolution
-
-2. **Integration Tests**:
-   - End-to-end sync workflows
-   - WebSocket connection testing
-   - API integration validation
-
-3. **E2E Tests**:
-   - Multi-device sync scenarios
-   - Offline/online transitions
-   - User interaction flows
-
-## Reporting Issues

-# OAuth Service Configuration Changes
-
-## Summary of Changes
-
-### 1. CORS Configuration Updated
-- **Before**: Restricted to specific origins (`http://localhost:5173,http://localhost:8080`)
-- **After**: Allows all origins (`*`) for maximum flexibility
-- **Implementation**: Updated CORS middleware to handle wildcard origins properly
-
-### 2. Dynamic Client URL Detection
-- **Before**: Hardcoded default client URL (`http://localhost:5173`)
-- **After**: Dynamically determines client URL from:
-  - Query parameter `redirect_uri` (highest priority)
-  - Request `Origin` header
-  - Request `Referer` header
-  - Fallback to `DEFAULT_CLIENT_URL` environment variable
-- **Implementation**: Enhanced `initiateGitHubOAuth` function with URL parsing logic
-
-### 3. Service Domain Configuration
-- **Added**: New `SERVICE_DOMAIN` environment variable
-- **Purpose**: Identifies the OAuth service domain in logs and webhook responses
-- **Current Value**: `https://oauth.tdvorak.dev`
-
-### 4. Enhanced Webhook Handling
-- **Before**: Basic webhook processing with minimal logging
-- **After**: 
-  - Proper webhook secret configuration check
-  - Enhanced logging with service domain identification
-  - Detailed event type handling with better payload logging
-  - Response includes service domain information
-
-### 5. Environment Files Updated
-- **`.env`**: Updated with new configuration values
-- **`.env.example`**: Updated to reflect the new structure for other deployments
-
-## Key Benefits
-
-1. **Multi-domain Support**: Service can now handle requests from any domain
-2. **Dynamic Client Detection**: Automatically redirects users back to their originating domain
-3. **Better Debugging**: Enhanced logging makes troubleshooting easier
-4. **Production Ready**: Configuration is more flexible for different deployment scenarios
-
-## Security Considerations
-
-- While CORS is set to allow all origins, the OAuth flow itself remains secure
-- State parameter validation prevents CSRF attacks
-- JWT tokens are still properly validated
-- Webhook signature validation is in place (though secret needs to be configured)
-
-## Usage
-
-The service will now:
-1. Accept OAuth requests from any domain
-2. Automatically detect the client's origin for proper redirects
-3. Handle webhooks with better logging and domain identification
-4. Work seamlessly with the user's domain (`tdvorak.dev`) and any other domains

-# Centralized OAuth Service
-
-This is a **standalone OAuth service** that handles GitHub authentication and email verification for all users. Users never need to set up their own OAuth applications - everything is centralized.
-
-## 🎯 **How It Works**
-
-### **For Users:**
-1. **GitHub OAuth**: Click "Connect GitHub" → GitHub authorization → Automatic login with GitHub profile
-2. **Email Verification**: Enter email → Receive verification code → Verify email for 2FA
-
-### **For Developers:**
-1. **Zero setup** - No OAuth app creation needed
-2. **Simple integration** - Just redirect to our service
-3. **Secure authentication** - We handle all the complexity
-4. **User management** - Centralized user database
-
-## 🚀 **Quick Start**
-
-### **1. Setup the OAuth Service**
-
-```bash
-# Navigate to the OAuth service
-cd oauth-service
-
-# Run the setup script
-./setup.sh
-
-# Edit the .env file with your GitHub OAuth credentials
-nano .env
-
-# Start the service
-go run main.go
-```
-
-### **2. GitHub OAuth App Setup (One Time)**
-
-1. Go to GitHub Settings → Developer settings → OAuth Apps
-2. Create a new OAuth app with:
-   - **Application name**: Trackeep OAuth Service
-   - **Homepage URL**: `http://localhost:9090`
-   - **Authorization callback URL**: `http://localhost:9090/auth/github/callback`
-3. Copy the Client ID and Client Secret to `.env`
-
-### **3. Email Verification Setup (One Time)**
-
-1. Configure smtp.purelymail.com for sending verification emails:
-   - **SMTP Host**: `smtp.purelymail.com`
-   - **SMTP Port**: `587`
-   - **Username**: Your purelymail SMTP username
-   - **Password**: Your purelymail SMTP password
-2. Add SMTP credentials to `.env` file
-3. The service will send 6-digit verification codes for 2FA
-
-### **4. Integration in Your App**
-
-```javascript
-// Redirect to GitHub OAuth
-const connectGitHub = () => {
-  window.location.href = 'http://localhost:9090/auth/github?redirect_uri=' + 
-    encodeURIComponent(window.location.origin);
-};
-
-// Send email verification code
-const sendEmailVerification = (email) => {
-  fetch('http://localhost:9090/api/v1/email/send', {
-    method: 'POST',
-    headers: { 'Content-Type': 'application/json' },
-    body: JSON.stringify({ email })
-  }).then(response => response.json())
-    .then(data => {
-      if (data.demo_code) {
-        console.log('Demo verification code:', data.demo_code);
-      }
-    });
-};
-
-// Verify email code
-const verifyEmailCode = (email, code) => {
-  fetch('http://localhost:9090/api/v1/email/verify', {
-    method: 'POST',
-    headers: { 'Content-Type': 'application/json' },
-    body: JSON.stringify({ email, code })
-  }).then(response => response.json())
-    .then(data => {
-      if (data.verified) {
-        console.log('Email verified successfully!');
-      }
-    });
-};
-
-// Handle callback (works for both GitHub and Email)
-const handleCallback = () => {
-  const urlParams = new URLSearchParams(window.location.search);
-  const token = urlParams.get('token');
-  const username = urlParams.get('user');
-  
-  if (token) {
-    localStorage.setItem('token', token);
-    localStorage.setItem('username', username);
-    // Redirect to dashboard
-    window.location.href = '/app';
-  }
-};
-```

-
-```javascript
-// App 1
-window.location.href = 'http://localhost:9090/auth/github?redirect_uri=http://app1.com';
-
-// App 2  
-window.location.href = 'http://localhost:9090/auth/github?redirect_uri=http://app2.com';

-# Trackeep Integration Guide
-
-## Architecture Overview
-
-This OAuth service is designed **only for authentication**. Trackeep instances (user-hosted) handle all GitHub data tracking directly.
-
-## How It Works
-
-### 1. User Authentication Flow
-1. User clicks "Login with GitHub" in Trackeep
-2. Trackeep redirects to: `https://oauth.tdvorak.dev/auth/github?redirect_uri=https://user-trackeep-instance.com`
-3. OAuth service handles GitHub authentication
-4. OAuth service redirects back: `https://user-trackeep-instance.com/auth/callback?token=JWT&user=username`
-
-### 2. What Trackeep Receives
-The JWT token contains:
-```json
-{
-  "user_id": 123,
-  "github_id": 456789,
-  "username": "johndoe",
-  "email": "john@example.com",
-  "access_token": "gho_16C7e42F292c6912E7710c838347Ae178B4a",
-  "token_type": "bearer",
-  "expires_at": 1738123456,
-  "exp": 1738123456,
-  "iat": 1737518656
-}
-```
-
-### 3. Trackeep GitHub API Access
-Trackeep instances can now make GitHub API calls using the user's `access_token`:
-
-```javascript
-// Example: Get user repositories
-const response = await fetch('https://api.github.com/user/repos', {
-  headers: {
-    'Authorization': `Bearer ${accessToken}`,
-    'Accept': 'application/vnd.github.v3+json'
-  }
-});
-
-// Example: Get commits for a repo
-const commits = await fetch(`https://api.github.com/repos/${owner}/${repo}/commits`, {
-  headers: {
-    'Authorization': `Bearer ${accessToken}`,
-    'Accept': 'application/vnd.github.v3+json'
-  }
-});
-```
-
-## Trackeep Implementation Guide
-
-### 1. OAuth Login Button
-```html
-<a href="https://oauth.tdvorak.dev/auth/github?redirect_uri=https://your-trackeep-instance.com">
-  Login with GitHub
-</a>
-```
-
-### 2. Handle OAuth Callback
-```javascript
-// In your /auth/callback route
-async function handleOAuthCallback(req, res) {
-  const { token, user: username } = req.query;
-  
-  // Decode and verify JWT
-  const jwtPayload = decodeJWT(token);
-  
-  // Store user session
-  req.session.user = {
-    id: jwtPayload.user_id,
-    username: jwtPayload.username,
-    email: jwtPayload.email,
-    githubAccessToken: jwtPayload.access_token,
-    tokenType: jwtPayload.token_type,
-    expiresAt: jwtPayload.expires_at
-  };
-  
-  // Redirect to dashboard
-  res.redirect('/dashboard');
-}
-```
-
-### 3. GitHub API Helper
-```javascript
-class GitHubAPI {
-  constructor(accessToken) {
-    this.accessToken = accessToken;
-  }
-  
-  async makeRequest(url) {
-    const response = await fetch(url, {
-      headers: {
-        'Authorization': `Bearer ${this.accessToken}`,
-        'Accept': 'application/vnd.github.v3+json'
-      }
-    });
-    return response.json();
-  }
-  
-  async getUserRepos() {
-    return this.makeRequest('https://api.github.com/user/repos');
-  }
-  
-  async getRepoCommits(owner, repo) {
-    return this.makeRequest(`https://api.github.com/repos/${owner}/${repo}/commits`);
-  }
-  
-  async getRepoPulls(owner, repo) {
-    return this.makeRequest(`https://api.github.com/repos/${owner}/${repo}/pulls`);
-  }
-  
-  async getBranches(owner, repo) {
-    return this.makeRequest(`https://api.github.com/repos/${owner}/${repo}/branches`);
-  }
-}
-```
-
-### 4. Track Data Collection
-```javascript
-// Example: Track repository activity
-async function trackRepositoryActivity(user, repoFullName) {
-  const [owner, repo] = repoFullName.split('/');
-  const github = new GitHubAPI(user.githubAccessToken);
-  
-  // Get commits
-  const commits = await github.getRepoCommits(owner, repo);
-  
-  // Get pull requests
-  const pulls = await github.getRepoPulls(owner, repo);
-  
-  // Store in your local database
-  await storeActivityData({
-    userId: user.id,
-    repo: repoFullName,
-    commits: commits.length,
-    pullRequests: pulls.length,
-    lastActivity: new Date()
-  });
-}
-```
-
-## Security Considerations
-
-### 1. Token Storage
-- Store GitHub access tokens securely (encrypted at rest)
-- Never expose tokens in client-side JavaScript
-- Use secure, HTTP-only cookies for session management
-
-### 2. Token Expiration
-- Monitor `expires_at` field in JWT
-- Refresh tokens before expiration if needed
-- Handle token expiry gracefully
-
-### 3. Rate Limiting
-- GitHub API has rate limits (5,000 requests/hour for authenticated users)
-- Implement caching to reduce API calls
-- Handle rate limit responses (HTTP 429)
-
-## Available GitHub Scopes
-
-The OAuth service requests these scopes:
-- `user:email` - Read user email addresses
-- `read:user` - Read user profile data  
-- `repo` - Access to repositories (full control)
-
-This allows Trackeep instances to:
-- Read repository data
-- Access commit history
-- Monitor pull requests
-- Track branch activity
-
-## API Endpoints
-
-### OAuth Service
-- `GET /auth/github` - Initiate OAuth flow
-- `GET /auth/github/callback` - Handle GitHub callback
-- `GET /api/v1/user/me` - Get current user info
-
-### GitHub API (via access token)
-- `GET /user/repos` - User repositories
-- `GET /repos/{owner}/{repo}/commits` - Repository commits
-- `GET /repos/{owner}/{repo}/pulls` - Pull requests
-- `GET /repos/{owner}/{repo}/branches` - Branches
-- And all other GitHub API endpoints
-
-## Benefits of This Architecture
-
-1. **Separation of Concerns** - OAuth service only handles authentication
-2. **User Privacy** - GitHub data stays in user's Trackeep instance
-3. **Scalability** - Each user instance handles its own GitHub API calls
-4. **Security** - No centralized GitHub data storage
-5. **Flexibility** - Trackeep can implement custom tracking logic
-

+# Database
+DB_HOST=postgres
+DB_PORT=5432
+DB_USER=trackeep
+DB_PASSWORD=<strong-password>
+DB_NAME=trackeep
+DB_SSL_MODE=disable
+
+# Security
+JWT_SECRET=<generate-with-openssl-rand-base64-32>

+# Optional: Search
+BRAVE_API_KEY=<your-key>
+
+# Optional: GitHub Integration
+GITHUB_CLIENT_ID=<your-client-id>
+GITHUB_CLIENT_SECRET=<your-client-secret>
+```
+
+## Deployment Steps
+
+### 1. Clone and Configure
+
+```bash
+# Clone repository
+git clone https://github.com/Dvorinka/Trackeep.git
+cd Trackeep
+
+# Copy environment template
+cp .env.example .env
+
+# Edit .env with your production values
+nano .env
+```
+
+### 2. Generate Security Keys
+
+```bash
+# Generate JWT secret
+openssl rand -base64 32
+
+# Generate encryption key
+openssl rand -base64 32
+
+# Add these to your .env file
+```
+
+### 3. Build and Deploy with Docker
+
+```bash
+# Build images
+docker-compose -f docker-compose.prod.yml build
+
+# Start services
+docker-compose -f docker-compose.prod.yml up -d
+
+# Check logs
+docker-compose -f docker-compose.prod.yml logs -f
+```
+
+### 4. Database Initialization
+
+The database will auto-migrate on first startup. To verify:
+
+```bash
+# Check database connection
+docker-compose -f docker-compose.prod.yml exec trackeep-backend /app/trackeep health
+
+# View migration logs
+docker-compose -f docker-compose.prod.yml logs trackeep-backend | grep migration
+```
+
+### 5. Create Admin User
+
+```bash
+# Access backend container
+docker-compose -f docker-compose.prod.yml exec trackeep-backend sh
+
+# Use the API to create first user (will be admin by default)
+curl -X POST http://localhost:8080/api/v1/auth/register \
+  -H "Content-Type: application/json" \
+  -d '{
+    "email": "admin@example.com",
+    "username": "admin",
+    "password": "SecurePassword123!",
+    "fullName": "Admin User"
+  }'
+```
+
+## Production Configuration
+
+### Nginx Reverse Proxy (Recommended)
+
+```nginx
+server {
+    listen 80;
+    server_name trackeep.example.com;
+    
+    # Redirect to HTTPS
+    return 301 https://$server_name$request_uri;
+}
+
+server {
+    listen 443 ssl http2;
+    server_name trackeep.example.com;
+
+    # SSL Configuration
+    ssl_certificate /etc/ssl/certs/trackeep.crt;
+    ssl_certificate_key /etc/ssl/private/trackeep.key;
+    ssl_protocols TLSv1.2 TLSv1.3;
+    ssl_ciphers HIGH:!aNULL:!MD5;
+
+    # Security Headers
+    add_header Strict-Transport-Security "max-age=31536000; includeSubDomains" always;
+    add_header X-Frame-Options "SAMEORIGIN" always;
+    add_header X-Content-Type-Options "nosniff" always;
+    add_header X-XSS-Protection "1; mode=block" always;
+
+    # Proxy to backend
+    location /api/ {
+        proxy_pass http://localhost:8080;
+        proxy_http_version 1.1;
+        proxy_set_header Upgrade $http_upgrade;
+        proxy_set_header Connection 'upgrade';
+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+        proxy_set_header X-Forwarded-Proto $scheme;
+        proxy_cache_bypass $http_upgrade;
+        
+        # Timeouts
+        proxy_connect_timeout 60s;
+        proxy_send_timeout 60s;
+        proxy_read_timeout 60s;
+    }
+
+    # Proxy to frontend
+    location / {
+        proxy_pass http://localhost:80;
+        proxy_http_version 1.1;
+        proxy_set_header Upgrade $http_upgrade;
+        proxy_set_header Connection 'upgrade';
+        proxy_set_header Host $host;
+        proxy_cache_bypass $http_upgrade;
+    }
+
+    # File upload size
+    client_max_body_size 100M;
+}
+```
+
+### Database Backup
+
+```bash
+# Create backup script
+cat > /usr/local/bin/backup-trackeep.sh << 'EOF'
+#!/bin/bash
+BACKUP_DIR="/var/backups/trackeep"
+DATE=$(date +%Y%m%d_%H%M%S)
+mkdir -p $BACKUP_DIR
+
+# Backup database
+docker-compose -f /path/to/docker-compose.prod.yml exec -T postgres \
+  pg_dump -U trackeep trackeep | gzip > $BACKUP_DIR/db_$DATE.sql.gz
+
+# Backup uploads
+tar -czf $BACKUP_DIR/uploads_$DATE.tar.gz /path/to/uploads
+
+# Keep only last 30 days
+find $BACKUP_DIR -name "*.gz" -mtime +30 -delete
+
+echo "Backup completed: $DATE"
+EOF
+
+chmod +x /usr/local/bin/backup-trackeep.sh
+
+# Add to crontab (daily at 2 AM)
+echo "0 2 * * * /usr/local/bin/backup-trackeep.sh" | crontab -
+```
+
+### Monitoring Setup
+
+```bash
+# Install monitoring tools
+docker-compose -f docker-compose.prod.yml -f docker-compose.monitoring.yml up -d
+
+# Access Grafana
+# http://localhost:3000 (default: admin/admin)
+
+# Access Prometheus
+# http://localhost:9090
+```
+
+## Security Checklist
+
+- [ ] Change all default passwords
+- [ ] Generate strong JWT_SECRET and ENCRYPTION_KEY
+- [ ] Enable HTTPS with valid SSL certificate
+- [ ] Configure firewall (allow only 80, 443)
+- [ ] Set up database backups
+- [ ] Enable rate limiting
+- [ ] Configure CORS properly
+- [ ] Set secure cookie flags
+- [ ] Enable audit logging
+- [ ] Set up monitoring and alerts
+- [ ] Review and restrict API access
+- [ ] Enable 2FA for admin accounts
+
+## Performance Optimization
+
+### Database Connection Pooling
+
+```go
+// Already configured in backend/config/database.go
+sqlDB, _ := DB.DB()
+sqlDB.SetMaxOpenConns(25)
+sqlDB.SetMaxIdleConns(10)
+sqlDB.SetConnMaxLifetime(time.Hour)
+sqlDB.SetConnMaxIdleTime(10 * time.Minute)
+```
+
+### Frontend Optimization
+
+```bash
+# Build optimized frontend
+cd frontend
+npm run build
+
+# Verify build size
+du -sh dist/
+```
+
+## Troubleshooting
+
+### Backend Won't Start
+
+```bash
+# Check logs
+docker-compose -f docker-compose.prod.yml logs trackeep-backend
+
+# Common issues:
+# 1. Database connection failed - check DB_HOST, DB_PASSWORD
+# 2. Port already in use - change BACKEND_PORT
+# 3. Missing environment variables - check .env file
+```
+
+### Database Connection Issues
+
+```bash
+# Test database connection
+docker-compose -f docker-compose.prod.yml exec postgres \
+  psql -U trackeep -d trackeep -c "SELECT version();"
+
+# Reset database (WARNING: deletes all data)
+docker-compose -f docker-compose.prod.yml down -v
+docker-compose -f docker-compose.prod.yml up -d
+```
+
+### High Memory Usage
+
+```bash
+# Check container stats
+docker stats
+
+# Restart services
+docker-compose -f docker-compose.prod.yml restart
+
+# Adjust memory limits in docker-compose.prod.yml
+```
+
+## Maintenance
+
+### Update Application
+
+```bash
+# Pull latest changes
+git pull origin main
+
+# Rebuild and restart
+docker-compose -f docker-compose.prod.yml build
+docker-compose -f docker-compose.prod.yml up -d
+
+# Check for migrations
+docker-compose -f docker-compose.prod.yml logs trackeep-backend | grep migration
+```
+
+### Database Maintenance
+
+```bash
+# Vacuum database
+docker-compose -f docker-compose.prod.yml exec postgres \
+  psql -U trackeep -d trackeep -c "VACUUM ANALYZE;"
+
+# Check database size
+docker-compose -f docker-compose.prod.yml exec postgres \
+  psql -U trackeep -d trackeep -c "SELECT pg_size_pretty(pg_database_size('trackeep'));"
+```
+
+### Log Rotation
+
+```bash
+# Configure Docker log rotation
+cat > /etc/docker/daemon.json << 'EOF'
+{
+  "log-driver": "json-file",
+  "log-opts": {
+    "max-size": "10m",
+    "max-file": "3"
+  }
+}
+EOF
+
+systemctl restart docker
+```
+
+## Scaling
+
+### Horizontal Scaling
+
+```yaml
+# docker-compose.prod.yml
+services:
+  trackeep-backend:
+    deploy:
+      replicas: 3
+      resources:
+        limits:
+          cpus: '1'
+          memory: 1G
+```
+
+### Load Balancer Configuration
+
+```nginx

+server {
+    listen 80;
+    server_name your-domain.com;
+    
+    location / {
+        proxy_pass http://localhost:80;
+        proxy_http_version 1.1;
+        proxy_set_header Upgrade $http_upgrade;
+        proxy_set_header Connection 'upgrade';
+        proxy_set_header Host $host;
+        proxy_cache_bypass $http_upgrade;
+    }
+    
+    location /api/ {
+        proxy_pass http://localhost:8080;
+        proxy_http_version 1.1;
+        proxy_set_header Upgrade $http_upgrade;
+        proxy_set_header Connection 'upgrade';
+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

+        proxy_cache_bypass $http_upgrade;
+    }
+    
+    client_max_body_size 100M;
+}
+```
+
+Enable and configure SSL:
+
+```bash
+# Enable site
+sudo ln -s /etc/nginx/sites-available/trackeep /etc/nginx/sites-enabled/
+
+# Test configuration
+sudo nginx -t
+
+# Install Certbot
+sudo apt install certbot python3-certbot-nginx -y
+
+# Get SSL certificate
+sudo certbot --nginx -d your-domain.com
+
+# Reload Nginx
+sudo systemctl reload nginx
+```
+
+## Optional: Configure Automated Backups
+
+```bash
+# Create backup script
+sudo nano /usr/local/bin/backup-trackeep.sh
+```
+
+Paste this script:
+
+```bash
+#!/bin/bash
+BACKUP_DIR="/var/backups/trackeep"
+DATE=$(date +%Y%m%d_%H%M%S)
+mkdir -p $BACKUP_DIR
+
+# Backup database
+docker-compose -f /path/to/Trackeep/docker-compose.prod.yml exec -T postgres \
+  pg_dump -U trackeep trackeep | gzip > $BACKUP_DIR/db_$DATE.sql.gz
+
+# Backup uploads
+tar -czf $BACKUP_DIR/uploads_$DATE.tar.gz /path/to/Trackeep/uploads
+
+# Keep only last 30 days
+find $BACKUP_DIR -name "*.gz" -mtime +30 -delete
+
+echo "Backup completed: $DATE"
+```
+
+Make it executable and schedule:
+
+```bash
+# Make executable
+sudo chmod +x /usr/local/bin/backup-trackeep.sh
+
+# Add to crontab (daily at 2 AM)
+(crontab -l 2>/dev/null; echo "0 2 * * * /usr/local/bin/backup-trackeep.sh") | crontab -
+```
+
+## Troubleshooting
+
+### Services won't start
+
+```bash
+# Check logs
+docker-compose -f docker-compose.prod.yml logs
+
+# Check specific service
+docker-compose -f docker-compose.prod.yml logs trackeep-backend
+
+# Restart services
+docker-compose -f docker-compose.prod.yml restart
+```

+
+```bash
+# Check database is running
+docker-compose -f docker-compose.prod.yml ps postgres
+
+# Check database logs
+docker-compose -f docker-compose.prod.yml logs postgres
+
+# Verify credentials in .env
+cat .env | grep DB_
+```
+
+### Port already in use
+
+```bash
+# Check what's using the port
+sudo lsof -i :8080
+sudo lsof -i :80
+

-### Service Architecture
+**Why this is CasaOS-ready:**
+- **Single service** — PostgreSQL runs inside the same container
+- **No `BACKEND_PORT`** — internal backend runs on 8081, only port 8080 is exposed
+- **Named volumes** — CasaOS handles them automatically
+- **Optional env vars** — if `DB_PASSWORD` or `JWT_SECRET` are empty, the container auto-generates them
+- **Icon header** — CasaOS reads the `icon:` field for the app tile
 
-Trackeep production deployment consists of **3 essential services**:
+### Optional Environment Variables
 
-#### **🎯 Frontend Service**
-- **Image**: `ghcr.io/dvorinka/trackeep/frontend:latest`
-- **Ports**: `80:80`, `443:443`
-- **Purpose**: Web interface and user experience
-- **Health**: Depends on backend service
-
-#### **🔧 Backend Service**
-- **Image**: `ghcr.io/dvorinka/trackeep/backend:latest`
-- **Ports**: `8080:8080`
-- **Purpose**: API server and business logic
-- **Health**: Built-in health check endpoint
-
-#### **🗄️ Database Service**
-- **Image**: `postgres:15-alpine`
-- **Purpose**: Data persistence and storage
-- **Health**: PostgreSQL readiness check
-- **Storage**: Persistent volume for data

-### Required Environment Variables
-
-Create a `.env` file from the provided `.env.example` and configure these required variables:
+All variables have sensible defaults. Only override what you need:
 
 ```env
-# Database Configuration
-DB_PASSWORD=your_secure_password
-POSTGRES_PASSWORD=your_secure_password

-# Security Configuration
-JWT_SECRET=your_jwt_secret_key
-ENCRYPTION_KEY=your_32_character_encryption_key

+DB_USER=trackeep
+DB_NAME=trackeep
+JWT_SECRET=your_jwt_secret_here         # auto-generated & persisted if empty
 ```
 
+**Note:** The frontend automatically connects to the backend via nginx proxy — no `VITE_API_URL` or additional configuration needed.

+## Desktop App (Tauri v2)
+
+Trackeep now includes a cross-platform desktop shell in [`desktop/`](./desktop/), powered by [Tauri v2](https://v2.tauri.app/).
+
+The desktop app opens each user's own self-hosted Trackeep instance URL, so everything stays connected to that instance:
+
+- Login/session handling
+- File upload/download
+- Realtime and API communication
+- Server-managed update behavior from your backend deployment
+- Native desktop integrations (sync folder, native file picker upload, quick sync actions)
+- Quick share actions with generated file share links copied to clipboard
+- Permission-aware token validation for desktop integrations
+- Cloud-drive ready workflows by selecting a OneDrive/Dropbox/Google Drive local folder as desktop sync source
+
+### Desktop development
+
+```bash
+cd desktop
+npm install
+npm run tauri:dev
+```
+
+### Desktop build (Linux / Windows / macOS)
+
+```bash
+cd desktop
+npm install
+npm run tauri:build
+```
+
+See [`desktop/README.md`](./desktop/README.md) for full setup details and prerequisites.
