+# Kubernetes: The Infrastructure Finale
+
+SystemCraft's journey started with **Docker** for isolation, moved to **Nginx** for reverse proxying, and now concludes with **Kubernetes** for robust orchestration.
+
+## 📁 Manifests Structure
+- `deployment.yaml`: Defing a 3-replica stateful-ready application with resource limits.
+- `service.yaml`: Internal connectivity via `ClusterIP`.
+- `ingress.yaml`: External routing via Nginx Ingress Controller (completing the Nginx journey).
+
+## 🚀 Deployment Strategy
+The CI/CD pipeline in `.github/workflows/ci.yml` is now integrated with these manifests:
+1. **Validation**: Every PR dry-runs the manifests to ensure zero syntax errors.
+2. **Build**: Docker images are pushed to GitHub Container Registry (GHCR).
+3. **Deploy**: Push to `main` triggers the deployment notification.
+
+## 🛠️ Local Testing (Minikube/Kind)
+To test the manifests locally:
+
+```bash
+# Create namespace
+kubectl create namespace system-craft
+
+# Apply manifests
+kubectl apply -f kubernetes/ -n system-craft
+
+# Verify pods
+kubectl get pods -n system-craft
+```
+
+---
+
+*This completes the full cycle: Dev -> Containerize -> Proxy -> Orchestrate.*
