+```
+
+3. Setup environment:
+```bash
+cp .env.example .env
+nano .env  # Edit dengan konfigurasi production
+```
+

+```bash
+mysql -u sql_retribusi -p sql_retribusi < migrations/001_create_audit_logs.sql
+mysql -u sql_retribusi -p sql_retribusi < migrations/002_create_hourly_summary.sql
+mysql -u sql_retribusi -p sql_retribusi < migrations/003_create_realtime_events.sql
