+## k3s Installation and Setup
+
+### 1. Install k3s
+
+```bash
+# Install k3s (single node setup)
+curl -sfL https://get.k3s.io | sh -
+
+# Wait for k3s to be ready
+sudo systemctl status k3s
+```
+
+### 2. Set up kubectl access
+
+```bash
+# Create .kube directory
+mkdir -p ~/.kube
+
+# Copy k3s kubeconfig
+sudo cp /etc/rancher/k3s/k3s.yaml ~/.kube/config
+
+# Fix permissions
+sudo chown $USER:$USER ~/.kube/config
+chmod 600 ~/.kube/config
+
+# Verify connection
+kubectl get nodes
+```
+
+### 3. Verify k3s is running
+
+```bash
+# Check node status
+kubectl get nodes
+
+# Check system pods
+kubectl get pods -A
+
+# Should see pods like: coredns, traefik, metrics-server, local-path-provisioner
+```
+
+### 4. Install ArgoCD
+
+```bash
+# Create namespace
+kubectl create namespace argocd
+```
+
+```bash
+# Download the manifest
+curl -o argocd-install.yaml https://raw.githubusercontent.com/argoproj/argo-cd/stable/manifests/install.yaml
+
+# Apply with server-side apply
+kubectl apply -f argocd-install.yaml --server-side --force-conflicts -n argocd
+
+# Wait for ArgoCD to be ready
+kubectl wait --for=condition=available --timeout=300s deployment/argocd-server -n argocd
+
+# Get initial admin password
+kubectl -n argocd get secret argocd-initial-admin-secret -o jsonpath="{.data.password}" | base64 -d && echo
+```
+
+### 5. Deploy the App via ArgoCD
+
+```bash
+# Apply Kong application
+kubectl apply -f iac/argocd/root-app.yaml
+
+# Watch deployment
+kubectl get applications -n argocd -w
+```
+
+### 6. Access Kong Gateway
+
+```bash
+# Wait for Kong to be ready
+kubectl wait --for=condition=ready pod -l app.kubernetes.io/name=kong -n kong --timeout=300s
+
+# Get Kong services
+kubectl get svc -n kong
+
+# Get LoadBalancer IP (k3s uses node IP)
+kubectl get svc -n kong kong-kong-proxy -o wide
+
+# Test Kong proxy (use your node's IP, usually your machine's IP)
+curl http://localhost
+```
+sd
+### 7. Access Kong Admin API
+
+```bash
+# Port forward to access admin API
+kubectl port-forward -n kong svc/kong-kong-admin 8001:8001
+
+# In another terminal, test admin API
+curl http://localhost:8001
+```
+
+### 8. Access ArgoCD UI (Optional)
+
+```bash
+# Port forward ArgoCD
+kubectl port-forward svc/argocd-server -n argocd 8080:443
+
+# Access at: https://localhost:8080
+# Username: admin
+# Password: (from step 4)
+```
+
+## Troubleshooting
+
+### Check k3s logs
+```bash
+sudo journalctl -u k3s -f
+```
+
+### Restart k3s if needed
+```bash
+sudo systemctl restart k3s
+```
+
+### Check Kong pods
+```bash
+kubectl get pods -n kong
+kubectl logs -n kong -l app.kubernetes.io/name=kong
+```
+
+### Check ArgoCD application status
+```bash
+kubectl get applications -n argocd
+kubectl describe application kong -n argocd
+```
