+### Kubernetes Usage
+
+To run GoChat using Kubernetes locally, you'll need to install a few prerequisites and use Minikube to create a local cluster with multiple nodes.
+
+#### 1. Install Prerequisites
+
+- [kubectl](https://kubernetes.io/docs/tasks/tools/) (Kubernetes CLI)
+- [Minikube](https://minikube.sigs.k8s.io/docs/start/) (1.32.0 or later)
+
+Ensure virtualization is enabled on your system (e.g., Hyper-V, VirtualBox, or Docker driver installed).
+
+#### 2. Start a Minikube Cluster with 2 Nodes
+
+Start Minikube with 2 nodes using:
+
+```
+minikube start --nodes=2
+```
+
+**Optional (for WSL/Windows users):** Start Minikube with Docker driver and custom resources:
+
+```
+minikube start --nodes=2 --driver=docker --cpus=2 --memory=2200
+```
+
+You can verify the nodes are running with:
+
+```
+kubectl get nodes
+```
+
+#### 3. Deploy the Application
+Navigate to the root of the project and apply the Kubernetes manifests:
+
+```
+kubectl apply -f kubernetes/
+```
+This will create:
+
+1. Deployments for frontend and backend
+
+2. Services to expose them
+
+3. Horizontal Pod Autoscalers (HPA)
+
+4. (Optional) Vertical Pod Autoscalers (VPA), if CRDs are installed
+
+#### 4. Access the Application
+Expose the frontend service using Minikube:
+
+```
+minikube service frontend-service
+```
+
+This will open the app in your default browser.
+
 ## Using the Application
