 ## Installing the Chart
 
-To install the chart with the release name `my-release`:
+Create an Istio enabled namespace:
 
 ```console
 kubectl create namespace demo
 kubectl label namespace demo istio-injection=enabled
 ```
 
-```console
-$ helm install podinfo-istio --name my-release -namespace demo
+Create an Istio Gateway in the `istio-system` namespace named `public-gateway`:
+
+```yaml
+apiVersion: networking.istio.io/v1alpha3
+kind: Gateway
+metadata:
+  name: public-gateway
+  namespace: istio-system
+spec:
+  selector:
+    istio: ingressgateway
+  servers:
+  - port:
+      number: 80
+      name: http
+      protocol: HTTP
+    hosts:
+    - "*"
+    tls:
+      httpsRedirect: true
+  - port:
+      number: 443
+      name: https
+      protocol: HTTPS
+    hosts:
+    - "*"
+    tls:
+      mode: SIMPLE
+      privateKey: /etc/istio/ingressgateway-certs/tls.key
+      serverCertificate: /etc/istio/ingressgateway-certs/tls.crt
 ```
 
-The command deploys podinfo-istio on the Kubernetes cluster in the default namespace.
-The [configuration](#configuration) section lists the parameters that can be configured during installation.
-
-## Uninstalling the Chart
-
-To uninstall/delete the `my-release` deployment:
+Create the `frontend` release by specifying the external domain name:
 
 ```console
-$ helm delete --purge my-release
+helm upgrade frontend --install ./charts/podinfo-istio \
+  --namespace=demo \
+  --set host=podinfo.example.com \
+  --set gateway.name=public-gateway \
+  --set gateway.create=false \
+  -f ./charts/podinfo-istio/frontend.yaml
 ```
 
-The command removes all the Kubernetes components associated with the chart and deletes the release.
-
-## Configuration
-
-The following tables lists the configurable parameters of the podinfo-istio.chart and their default values.
-
-Parameter | Description | Default
---- | --- | ---
-`affinity` | node/pod affinities | None
-`hpa.enabled` | Enables HPA | `false`
-`hpa.cpu` | Target CPU usage per pod | None
-`hpa.memory` | Target memory usage per pod | None
-`hpa.requests` | Target requests per second per pod | None
-`hpa.maxReplicas` | Maximum pod replicas | `10`
-`ingress.hosts` | Ingress accepted hostnames | None
-`ingress.tls` | Ingress TLS configuration | None:
-`image.pullPolicy` | Image pull policy | `IfNotPresent`
-`image.repository` | Image repository | `stefanprodan/podinfo-istio.
-`image.tag` | Image tag | `0.0.1`
-`ingress.enabled` | Enables Ingress | `false`
-`ingress.annotations` | Ingress annotations | None
-`ingress.hosts` | Ingress accepted hostnames | None
-`ingress.tls` | Ingress TLS configuration | None
-`nodeSelector` | node labels for pod assignment | `{}`
-`podAnnotations` | annotations to add to each pod | `{}`
-`replicaCount` | desired number of pods | `1`
-`resources.requests/cpu` | pod CPU request | `1m`
-`resources.requests/memory` | pod memory request | `16Mi`
-`resources.limits/cpu` | pod CPU limit | None
-`resources.limits/memory` | pod memory limit | None
-`service.externalPort` | external port for the service | `9898`
-`service.internalPort` | internal port for the service | `9898`
-`service.nodePort` | node port for the service | `31198`
-`service.type` | type of service | `ClusterIP`
-`tolerations` | List of node taints to tolerate | `[]`
-
-Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,
+Create the `backend` release:
 
 ```console
-$ helm install stable/podinfo-istio.--name my-release \
-  --set=image.tag=0.0.2,service.type=NodePort
+helm upgrade backend --install ./charts/podinfo-istio \
+  --namespace=demo \
+  -f ./charts/podinfo-istio/backend.yaml 
 ```
 
-Alternatively, a YAML file that specifies the values for the above parameters can be provided while installing the chart. For example,
+Create the `store` release:
 
 ```console
-$ helm install podinfo-istio --name my-release -f values.yaml
+helm upgrade store --install ./charts/podinfo-istio \
+  --namespace=demo \
+  -f ./charts/podinfo-istio/store.yaml 
 ```
 
-> **Tip**: You can use the default [values.yaml](values.yaml)
-```
