+
+## Quick Setup (Copy & Paste)
+
+```bash
+# 1. Navigate to project directory
+cd /opt/app/backend/lottery-be
+
+# 2. Load database password
+source scripts/load-db-password.sh
+
+# 3. Start phpMyAdmin
+docker-compose -f docker-compose.prod.yml up -d phpmyadmin
+
+# 4. Verify it's running
+docker ps | grep phpmyadmin
+
+# 5. Open firewall port
+sudo ufw allow 8081/tcp
+sudo ufw reload
+
+# 6. Get your VPS IP (if you don't know it)
+hostname -I | awk '{print $1}'
+```
+
+## Access phpMyAdmin
+
+**URL**: `http://YOUR_VPS_IP:8081`
+
+**Login Credentials**:
+- **Server**: `db` (or leave default)
+- **Username**: `root`
+- **Password**: Get it with: `grep SPRING_DATASOURCE_PASSWORD /run/secrets/lottery-config.properties`
+
+## Security: Restrict Access to Your IP Only
+
+```bash
+# Get your current IP
+curl ifconfig.me
+
+# Remove open access
+sudo ufw delete allow 8081/tcp
+
+# Allow only your IP (replace YOUR_IP with your actual IP)
+sudo ufw allow from YOUR_IP to any port 8081
+
+# Reload firewall
+sudo ufw reload
+```
+
+## Verify Everything Works
+
+```bash
+# Check container is running
+docker ps | grep phpmyadmin
+
+# Check logs
+docker logs lottery-phpmyadmin
+
+# Test connection from browser
+# Open: http://YOUR_VPS_IP:8081
+```
+
+## Common Issues
+
+**Container won't start?**
+```bash
+# Make sure password is loaded
+source scripts/load-db-password.sh
+echo $DB_ROOT_PASSWORD
+
+# Restart
+docker-compose -f docker-compose.prod.yml restart phpmyadmin
+```
+
+**Can't access from browser?**
+```bash
+# Check firewall
+sudo ufw status | grep 8081
+
+# Check if port is listening
+sudo netstat -tlnp | grep 8081
+```
+
+**Wrong password?**
+```bash
+# Get the correct password
+grep SPRING_DATASOURCE_PASSWORD /run/secrets/lottery-config.properties
+```
