+# ⚙️ GitOps with ArgoCD – JSON Server Demo
+
+This project demonstrates a **GitOps workflow using ArgoCD** to automatically deploy a simple `json-server` application to a Kubernetes cluster.
+
+📌 **Showcase Ready** — You can include this in your resume or portfolio to demonstrate your understanding of:
+- Kubernetes deployment workflows
+- GitOps principles
+- ArgoCD for continuous delivery
+- Docker-based microservices
+
+---
+
+## 🔍 What This Project Demonstrates
+
+- 🎯 Deploying a demo app (`json-server`) using ArgoCD
+- 📂 Managing Kubernetes manifests declaratively from Git
+- 🔄 Continuous sync between Git and the cluster
+- 🛠 Rollbacks, health checks, and namespace scoping
+- 🔧 Manual + automatic deployment syncing
+
+---
+
+## 🗂 Project Structure
+
+- ├── manifests/
+- │ ├── deployment.yaml
+- │ └── service.yaml
+- └── Dockerfile
