+# Use Helm to deploy Cloudant provider and package
+
+This chart is to deploy Cloudant provider and package to OpenWhisk on a Kubernetes using Helm.
+
+## Preconditions
+
+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 below configuration in the `mycluster.yaml` when you deploy OpenWhisk with Helm:
+```
+# 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/cloudant --namespace=openwhisk --name owdev-cloudant-provider
+```
+
+You can use `helm status owdev-alarm-provider` to check the status. When you see pod is running and job is completed, you can check alarm package by `wsk package get /whisk.system/alarms -i --summary`
