+## Overview
+
+The **Petclinic Demo Application** is a deployment of the Spring PetClinic sample application, tailored for demonstration purposes. It showcases a modern Java-based microservice architecture, leveraging Spring Boot for rapid development and deployment. The application is deployed via ArgoCD into the `demo-apps` namespace and includes integrations for observability, load testing, and chaos engineering.
+
+This service plays a critical role in demonstrating best practices for application lifecycle management, including CI/CD workflows, OpenTelemetry instrumentation, and Kubernetes-based deployments. It serves as a reference implementation for teams adopting similar technologies and workflows.

+
+## Architecture
+
+The Petclinic Demo Application is built on the Spring Boot framework and deployed as a containerized service in Kubernetes. Key architectural components include:
+
+- **Spring Boot Application**: The core service, providing RESTful APIs and a web interface.
+- **Database**: Configurable to use H2 (in-memory), MySQL, or PostgreSQL, depending on the active profile.
+- **OpenTelemetry Integration**: Auto-instrumentation for tracing, metrics, and logs, exported to an OTel Collector.
+- **ArgoCD**: Continuous deployment and synchronization from the `main` branch.
+- **K6 Load Testing**: Configured for performance testing.
+- **Chaos Mesh**: Enabled for chaos engineering experiments.
+
+Data flows through the application from user interactions to backend services, with observability tools providing insights into performance and reliability.

+## Overview
+
+`sonar-test-nest4` is a stateless microservice built using the `typescript-nestjs` runtime. It was scaffolded from the **Create Microservice** golden-path template on the Kyndryl Platform. The service provides a REST API for managing items, including endpoints for CRUD operations. It is designed to be lightweight, scalable, and observable, with integrated OpenTelemetry instrumentation and Prometheus metrics.
+
+This service plays a critical role in the demo-apps domain, serving as a testbed for platform capabilities such as CI/CD pipelines, observability, and load testing. It is managed via Humanitec and deployed to Azure Kubernetes Service (AKS) using Score-based configurations.

+
+## Architecture
+
+`sonar-test-nest4` follows a modern microservice architecture with the following components:
+
+- **Runtime**: `typescript-nestjs`
+- **Container Port**: `3000`
+- **Endpoints**:
+  - `/api/items` for CRUD operations
+  - `/health` for health checks
+  - `/metrics` for Prometheus metrics
+- **Deployment**:
+  - Images are built and pushed to Azure Container Registry (ACR).
+  - Humanitec API triggers deployments to AKS using Score-based configurations.
+- **CI/CD**:
+  - Gitea Actions workflows (`build-push.yml` and `deploy-humanitec.yml`) automate build, test, and deployment processes.
+  - Promotion between environments (`dev → staging → prod`) is gated by CI checks and manual approvals.
+
+## Configuration
+
+| Config Key       | Value              |
+|------------------|--------------------|
+| `runtime`        | `typescript-nestjs` |
+| `health_path`    | `/health`          |
+| `container_port` | `3000`             |
+
+Additional configuration options are managed via `.platform/config.yaml` and Humanitec score files.
+
+## Operations
+
+### Deployment Flow
+
+1. Push changes to the `dev` branch to trigger automatic builds and deployments to the dev environment.
+2. Promote changes to `staging` or `prod` via PRs, requiring CI checks and one approval.
+3. Use Backstage's CI/CD tab to monitor and trigger promotions between environments.
+
+### Runbook Notes
+
+- **Health Check**: Verify service health via `/health`.
+- **Metrics**: Access Prometheus metrics at `/metrics`.
+- **Load Testing**: K6 is enabled for load testing, with configurations stored in the `k6-test-sonar-test-nest4` ConfigMap.
+
+## Observability
+
+- **Grafana Dashboard**: [OpenTelemetry Application Observability](https://grafana.kyndemo.live/d/otel-app-observability-v2/opentelemetry-application-observability?orgId=1&var-app=sonar-test-nest4)
+- **Prometheus Metrics**: Exposed at `/metrics` on port `3000`.
