+# Use Helm to deploy kafka provider and package
+
+This chart is to deploy the kafka provider and package to OpenWhisk on a Kubernetes using
Helm.
+
+## Preconditions
+
+If you intend to use a Kafka instance that is external to Kubernetes as your broker, you
can stop reading this section; there are no additional preconditions.
+However, if you want to use the Kakfa instance that is installed as part of the OpenWhisk
deployment as your Kafka broker, you need to configure your OpenWhisk deployment so that the
action containers use Kubernetes DNS. The easiest way to do this is to use the `KubernetesContainerFactory`
as the [Invoker Container Factory](https://github.com/apache/incubator-openwhisk-deploy-kube/blob/master/docs/configurationChoices.md#invoker-container-factory)
in the Kubernetes cluster by adding belo [...]
+```
+# Invoker configurations
+invoker:
+  containerFactory:
+    impl: "kubernetes"
+```
+If you want to use the `DockerContainerFactory` you can instead attempt to configure the
invoker to use Kubernetes DNS. First you can get the IP address of Kubernetes DNS server by
`echo $(kubectl get svc kube-dns -n kube-system -o 'jsonpath={.spec.clusterIP}')` and then
add below configuration in the `mycluster.yaml`:
+```
+# Invoker configurations
+invoker:
+  kube_dns: "<IP_Address_Of_Kube_DNS>"
+```
+
+## Install
+
+You may install this chart with command like
+```
+helm install ./helm/providers/charts/kafka --namespace=openwhisk --name owdev-kafka-provider
+```
+
+You can use `helm status owdev-kafka-provider` to check the status. When you see pod is running
and job is completed, it should be ready to use.
