 # Sonar Test Nest4
 
-> A stateless microservice built with TypeScript and NestJS, providing API endpoints for item management and Prometheus-based observability.
+> A stateless microservice built with TypeScript and NestJS, providing API endpoints for item management and integrated observability features.
 
 ## Overview
 
-Sonar Test Nest4 is a stateless microservice scaffolded from the **Create Microservice** golden-path template on the Kyndryl Platform. It is designed to manage items through a RESTful API and includes built-in observability features such as health checks and Prometheus metrics.
+Sonar Test Nest4 is a stateless microservice scaffolded from the **Create Microservice** golden-path template on the Kyndryl Platform. It is implemented using the `typescript-nestjs` runtime and is designed to manage items through a RESTful API. The service includes built-in observability features such as health checks and Prometheus metrics.
 
-The service is implemented using the `typescript-nestjs` runtime and follows a structured branch model (`dev`, `staging`, `prod`, and `main`) to ensure smooth CI/CD workflows. It is deployed to Azure Kubernetes Service (AKS) via Humanitec, with container images stored in Azure Container Registry (ACR).
+The service follows a structured branch model (`dev → staging → prod → main`) to ensure smooth CI/CD workflows. Application code resides in the `dev` branch, which triggers automatic builds and deployments to the development environment. Promotions to staging and production require pull requests with CI gates and approvals.
 
-This service plays a key role in the broader system by providing item management capabilities and adhering to platform standards for observability, deployment, and runtime configuration.
+Sonar Test Nest4 integrates with Azure Container Registry for image storage and Humanitec for deployment orchestration, targeting an AKS cluster. Observability is enhanced with OpenTelemetry instrumentation and a Grafana dashboard for monitoring.

 ## Operations
 
-The service follows a structured branch model for development and deployment:
+### Deployment Steps
 
-- **dev**: Active development branch; commits trigger automatic builds and deployments to the dev environment.
-- **staging**: Pre-production environment; changes are promoted from `dev` via PR with CI gate and approval.
-- **prod**: Production environment; changes are promoted from `staging` via PR with CI gate and approval.
-- **main**: System of record; receives merges from `prod` after releases.
+1. Push changes to the `dev` branch to trigger automatic builds and deployments to the development environment.
+2. Open a pull request for promotion to `staging` or `prod`. Ensure CI tests pass and obtain one approval.
+3. Merge the pull request to promote the service to the target environment.
+4. Application code is merged into the `main` branch from `prod` after releases.
 
-Deployment workflows are runtime-agnostic and rely on `.platform/config.yaml` for configuration.
+### Branch Model
+
+| Branch | Purpose |
+|---|---|
+| dev | Active development — push freely, deploys to dev environment automatically. |
+| staging | Pre-production — promoted from dev via PR (CI gate + 1 approval). |
+| prod | Production — promoted from staging via PR (CI gate + 1 approval). |
+| main | System of record — receives merges from prod after releases. |
 
 ## Observability
 
-- [Grafana Dashboard](https://grafana.kyndemo.live/d/otel-app-observability-v2/opentelemetry-application-observability?orgId=1&var-app=sonar-test-nest4): OpenTelemetry-based application observability.
-- Prometheus metrics exposed at `/metrics`.
-- Health check endpoint at `/health`.
+| Observability Feature | Description |
+|---|---|
+| Health Check | `/health` endpoint returns `{"status":"UP"}`. |
+| Metrics | `/metrics` endpoint exposes Prometheus metrics. |
+| Grafana Dashboard | [OpenTelemetry Application Observability](https://grafana.kyndemo.live/d/otel-app-observability-v2/opentelemetry-application-observability?orgId=1&var-app=sonar-test-nest4). |
