 ## Description
 
-[Nest](https://github.com/nestjs/nest) framework TypeScript starter repository.
+[SMALDA](https://github.com/RUKAYAT-CODER/SMALDA) - Secure Document Management and Ledger Anchoring system built with NestJS.
+
+## Database Migrations
+
+This project uses TypeORM migrations for database schema management.
+
+### Migration Commands
+
+```bash
+# Generate a new migration
+npm run migration:generate -- -n MigrationName
+
+# Run all pending migrations
+npm run migration:run
+
+# Revert the last migration
+npm run migration:revert
+
+# Show migration status
+npm run migration:show
+
+# Run migrations with CI/CD script
+npm run migrate
+```
+
+### Migration Files
+
+Migration files are located in `src/migrations/` and are automatically compiled to `dist/migrations/`.
+
+### CI/CD Integration
+
+The deployment pipeline automatically runs migrations before starting the application:
+
+1. Database connection check
+2. Run pending migrations
+3. Start the application
