+# Deploying GCS with Helm
+
+## Download Helm
+
+Helm can be obtained from the [Helm
+releases](https://github.com/helm/helm/releases) page.
+
+## Install Helm & Tiller
+
+Once you have downloaded Helm, you need to install it. The Helm client is
+installed locally, and Tiller runs within your Kubernetes cluster.
+
+Assuming you have RBAC installed on your cluster, you need to create a service
+account for Helm to use. The provided `helm-sa.yaml` creates a service account
+in the `kube-system` namespace called "tiller" and gives it cluster admin
+permissions. This allows Tiller to deploy charts anywhere in the cluster.
+
+**Note: These instructions do not set up TLS security for Helm, so it should
+not be considered a secure configuration. Patches welcome.**
+
+Install the SA:
+
+```bash
+$ kubectl apply -f helm-sa.yaml
+serviceaccount "tiller" created
+clusterrolebinding.rbac.authorization.k8s.io "tiller" created
+```
+
+Install Tiller & initialize local Helm state:
+
+```bash
+$ helm --kubeconfig=../deploy/kubeconfig init --service-account tiller
+$HELM_HOME has been configured at /home/jstrunk/.helm.
+
+Tiller (the Helm server-side component) has been installed into your Kubernetes Cluster.
+
+Please note: by default, Tiller is deployed with an insecure 'allow unauthenticated users' policy.
+To prevent this, run `helm init` with the --tiller-tls-verify flag.
+For more information on securing your installation see: https://docs.helm.sh/using_helm/#securing-your-helm-installation
+Happy Helming!
+```
+
+Verify it is installed:
+
+```bash
+$ helm --kubeconfig=../deploy/kubeconfig version
+Client: &version.Version{SemVer:"v2.10.0", GitCommit:"9ad53aac42165a5fadc6c87be0dea6b115f93090", GitTreeState:"clean"}
+Server: &version.Version{SemVer:"v2.10.0", GitCommit:"9ad53aac42165a5fadc6c87be0dea6b115f93090", GitTreeState:"clean"}
+```
+
+## Configure GCS for your cluster
+
+There isn't much that is currently configurable, but what exists is in `gluster-container-storage/values.yaml`.
+
+## Deploy GCS
+
+Download chart dependencies (etcd-operator):
+
+```bash
+$ helm dependency update gluster-container-storage
+Hang tight while we grab the latest from your chart repositories...
+...Unable to get an update from the "local" chart repository (http://127.0.0.1:8879/charts):
+	Get http://127.0.0.1:8879/charts/index.yaml: dial tcp 127.0.0.1:8879: connect: connection refused
+...Successfully got an update from the "stable" chart repository
+Update Complete. ⎈Happy Helming!⎈
+Saving 1 charts
+Downloading etcd-operator from repo https://kubernetes-charts.storage.googleapis.com
+Deleting outdated charts

+
+Install GCS chart:
+
+```bash
+$ helm --kubeconfig=../deploy/kubeconfig install --namespace gcs gluster-container-storage
