+## Application Type
+Java Application
+
+## Selected Modernization Strategy
+- **Migration Approach**: containerize-optimize
+- **Target Platform**: humanitec-v2
+- **Observability**: ENABLED (Prometheus metrics, health checks, tracing)
+- **Security Scanning**: ENABLED (Trivy vulnerability scanning)
+
+## Discovery Summary
+### Discovery Report
+
+#### Application Overview
+The application is a Java-based project, primarily using the Spring Boot framework. Both Maven and Gradle build tools are present, but Maven appears to be the primary build tool based on the dependencies listed in `pom.xml`.
+
+#### Technology Stack

+- **Build Tools**: Maven (primary), Gradle (secondary)
+- **Database**: H2 (in-memory), MySQL, PostgreSQL
+- **Frontend**: Thymeleaf templates, ...
+
+## Generated Artifacts
+1. **Dockerfile**: Optimized with health checks and metrics endpoints
+2. **score.yaml**: Platform intent with service ports and DNS resource
+3. **CI Workflow**: Automated build/push to ACR with Trivy security scanning
+
+## Next Steps
+1. Review and customize generated artifacts
+2. Test container build and run
+3. Deploy to development environment using score.yaml
+4. Validate application functionality
+5. Promote to staging/production via Humanitec
+
+## Migration Strategy Details
+
+### Containerize Optimize
+Add cloud-native patterns: health checks, metrics, optimized base images.
+
+### Platform: humanitec-v2
+score.yaml optimized for Azure Container Apps with managed scaling and Azure-specific configuration.
