+### 1. Create Admin User
+
+```bash
+cd server
+node -e "
+const { User } = require('./models');
+(async () => {
+  try {
+    const admin = await User.create({
+      name: 'Admin User',
+      email: 'admin@yourdomain.com',
+      preferences: { role: 'admin' },
+      isActive: true
+    });
+    console.log('✅ Admin user created:', admin.email);
+  } catch(e) {
+    console.error('❌ Error:', e.message);
+  }
+})();
+"
+```
+
+### 2. Load Default Assistants (Optional)
+
+If you have the assistant data file:
+
+```bash
+cd server
+node -e "
+const fs = require('fs');
+const { Assistant } = require('./models');
+const assistantsData = JSON.parse(fs.readFileSync('./data/assistants.json'));
+(async () => {
+  try {
+    await Assistant.bulkCreate(assistantsData);
+    console.log('✅ Default assistants loaded');
+  } catch(e) {
+    console.error('❌ Error:', e.message);
+  }
+})();
+"
+```
+
+### 3. Verify Data
+
+```bash
+psql -h localhost -U ideas_gen_user -d ideas_gen_dev -c "SELECT COUNT(*) FROM assistants;"
+psql -h localhost -U ideas_gen_user -d ideas_gen_dev -c "SELECT COUNT(*) FROM users;"

+    return 301 https://$server_name$request_uri;
+}
+
+server {
+    listen 443 ssl http2;
+    server_name your-domain.com;
+
+    ssl_certificate /path/to/your/certificate.crt;
+    ssl_certificate_key /path/to/your/private.key;
+
+    # Frontend static files
+    location / {
+        root /var/www/ideas-gen-2025/admin/dist;
+        try_files $uri $uri/ /index.html;
+    }
+
+    # API proxy
+    location /api {
+        proxy_pass http://localhost:3000;
+        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;
+    }
+}
+```
+
+### 2. Setup SSL (Let's Encrypt)
+
+```bash
+sudo apt install certbot python3-certbot-nginx
+sudo certbot --nginx -d your-domain.com
+```
+
+### 3. Setup Process Manager
+
+```bash
+cd server
+pm2 start index.js --name "ideas-gen-2025" --env production
+pm2 save
+pm2 startup
+```
+
+## 🔍 Troubleshooting
+
+### Common Issues

+
+**Solutions**:
+```bash
+# Check PostgreSQL status
+sudo systemctl status postgresql
+
+# Restart PostgreSQL
+sudo systemctl restart postgresql
+
+# Verify database exists
+psql -l | grep ideas_gen
+
+# Recreate database if needed
+createdb -U ideas_gen_user ideas_gen_dev
+```
+
+#### 2. OpenAI API Errors
+
+**Error**: `Invalid API key` or `Rate limit exceeded`
+
+**Solutions**:
+- Verify API key in `.env` file
+- Check OpenAI account billing and limits

+curl -H "Authorization: Bearer $OPENAI_API_KEY" \
+     https://api.openai.com/v1/models
+```
+
+#### 3. File Upload Issues
+
+**Error**: `ENOENT: no such file or directory`
+
+**Solutions**:
+```bash
+# Create uploads directory
+mkdir -p server/uploads
+chmod 755 server/uploads
+
+# Check file size limits in .env
+MAX_FILE_SIZE=10485760  # 10MB
+```
+
+#### 4. Frontend Build Errors
+
+**Error**: `Module not found` or build failures
+
+**Solutions**:

+# Clear Vite cache
+rm -rf admin/.vite
+```
+
+#### 5. CORS Issues
+
+**Error**: `blocked by CORS policy`
+
+**Solutions**:
+- Check `CORS_ORIGIN` in server `.env`
+- Verify frontend URL matches CORS setting
+- For development, use: `CORS_ORIGIN=http://localhost:5173`
+
+### Debug Commands
+
+```bash
+# Check server logs
+cd server && npm run dev
+
+# Test database connection
+node -e "const {sequelize} = require('./models'); sequelize.authenticate().then(() => console.log('✅ DB OK')).catch(console.error);"
+
+# Test API endpoints
+curl http://localhost:3000/health
+curl http://localhost:3000/api/assistants
+
+# Check frontend build
+cd admin && npm run build
+
+# Test production build locally
+cd admin && npm run preview
+```
+
+## 🔧 Maintenance
+
+### Regular Tasks
+
+#### 1. Database Backups
+
+```bash
+# Create backup script
+#!/bin/bash
+DATE=$(date +%Y%m%d_%H%M%S)
+pg_dump -h localhost -U ideas_gen_user ideas_gen_prod > backup_$DATE.sql
+
+# Automate with cron
+echo "0 2 * * * /path/to/backup_script.sh" | crontab -
+```
+
+#### 2. Log Rotation
+
+```bash
+# Setup logrotate for PM2
+sudo nano /etc/logrotate.d/pm2
+
+/home/user/.pm2/logs/*.log {
+    daily
+    missingok
+    rotate 7
+    compress
+    notifempty
+    create 0644 user user
+    postrotate
+        pm2 reloadLogs
+    endscript
+}
+```
+
+#### 3. Security Updates
+
+```bash
+# Update dependencies monthly
+cd server && npm audit fix
+cd admin && npm audit fix
+
+# Update system packages
+sudo apt update && sudo apt upgrade
+```
+
+#### 4. Performance Monitoring
+
+```bash
+# Monitor with PM2
+pm2 monit
+
+# Check system resources
+htop
+df -h
+free -h
+
+# Monitor database
+psql -c "SELECT * FROM pg_stat_activity;"
+```
+
+### Scaling Considerations
+
+#### 1. Database Scaling
+- Consider PostgreSQL read replicas for heavy read workloads
+- Implement connection pooling with `pg-pool`
+- Monitor query performance and add indexes
+
+#### 2. Application Scaling
+- Use PM2 cluster mode: `pm2 start index.js -i max`
+- Implement Redis for session storage
+- Consider load balancer for multiple servers
+
+#### 3. Storage Scaling
+- Use cloud storage (AWS S3, Google Cloud Storage) for file uploads
+- Implement CDN for static assets
+- Regular cleanup of old conversation data
