-Istio Installation
 
-1. Download the Source code
-curl -L https://git.io/getLatestIstio | ISTIO_VERSION=1.1.7 sh -
-
-2. Add the ISTIO helm chart repository. “helm repo add istio.io https://storage.googleapis.com/istio-release/releases/1.1.7/charts/”
-
-    NOTE : Make sure the helm client and helm server (tiller) is installed
-
-    Create a namespace istio-system where all the istio components are installed “kubectl create namespace istio-system”
-
-3. Install all the Istio Custom Resource Definitions (CRDs) using kubectl apply
-
-
-   “helm template install/kubernetes/helm/istio-init --name istio-init --namespace istio-system | kubectl apply -f -”.
-
-4. Verify that all 53 Istio CRDs were committed to the Kubernetes api-server using the following command:
-
-    “kubectl get crds | grep 'istio.io\|certmanager.k8s.io' | wc -l”
-
-5. Install istio with the sds as the configuration profile.
-
-   “helm template install/kubernetes/helm/istio --name istio --namespace istio-system --values install/kubernetes/helm/istio/values-istio-sds-auth.yaml | kubectl apply -f -”
-
-6.  Verify the Installation
-
-    “kubectl get svc -n istio-system” && “kubectl get pods -n istio-system”

+## Prerequisites
+
+- Kubernetes 1.10.0+
+
+## Installing the chart
+
+To install the chart from local directory:
+
+```
+helm install --name=istio-operator --namespace=istio-system istio-operator
+```
+
+## Uninstalling the Chart
+
+To uninstall/delete the `istio-operator` release:
+
+```
+$ helm del --purge istio-operator
