 ## Development Workflow
 
+### Manual Setup
 1. Start database: `bash tools/run-docker-db.sh`
 2. Start backend: `bash tools/run-docker-server.sh` or `cd server && ./mvnw spring-boot:run`
 3. Start frontend: `bash tools/run-docker-client.sh` or `cd client && npm start`
 4. Access app at http://localhost:5000
 
+### Using Taskfile
+Alternatively, use the Taskfile.yml for automated workflows:
+```bash
+task dev-run          # Start development environment (docker-compose.dev.yml)
+task prod-up          # Start production environment (docker-compose.prod.yml)
+task docker-build-api # Build server Docker image
+task docker-build-web # Build app Docker image
+task -l               # List all available tasks
+```
+
+### Quality Checks
 Always run quality checks before submitting changes:
 - Frontend: `bash tools/check-frontend.sh`
 - Backend: `bash tools/check-backend.sh`
