+This service is built with **Java Spring Boot** and follows the Golden Path architecture patterns.
+
+### Key Features
+
+- 🚀 Production-ready configuration
+- 📊 Prometheus metrics exposed
+- 🏥 Health check endpoints
+- 🔒 Security scanning in CI/CD
+- 📦 Containerized deployment
+
+## Quick Start
+
+```bash
+git clone https://gitea.kyndemo.live/kyndryl-demos/vetclinic.git
+cd vetclinic
+```
+
+## Monitoring
+
+- **Metrics**: Prometheus metrics at `/metrics`
+- **Health**: `/health`

+# Modernization Plan for vetclinic
+
+## Application Type
+Java Application
+
+## Selected Modernization Strategy
+- **Migration Approach**: containerize-optimize
+- **Target Platform**: kubernetes-humanitec
+- **Observability**: ENABLED (Prometheus metrics, health checks, tracing)
+- **Security Scanning**: ENABLED (Trivy vulnerability scanning)
+
+## Discovery Summary
+### Discovery Report
+
+#### Application Overview
+The application appears to be a Java-based web application built using the Spring Boot framework. It includes both Maven and Gradle build files, suggesting flexibility in build tool usage. The presence of `spring-petclinic` indicates that this might be a sample or reference application for Spring Boot.
+
+#### Technology Stack
+- **Programming Language:** Java
+- **Framework:** Spring Boot
+- **Build Tools:** Maven (`pom.xml`) and Gradle (`build.gradle`...
+
+## Generated Artifacts
+1. **Dockerfile**: Optimized with health checks and metrics endpoints
+2. **score.yaml**: Platform-agnostic environment intent optimized for kubernetes-humanitec with Prometheus metrics resources
+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: kubernetes-humanitec
+score.yaml is the single environment intent. Use Humanitec Platform Orchestrator for deployment.
