+# Stash
+[Stash by AppsCode](https://github.com/appscode/stash) - Backup your Kubernetes Volumes
+## TL;DR;
+
+```bash
+$ helm install stable/stash
+```
+
+## Introduction
+
+This chart bootstraps a [Stash controller](https://github.com/appscode/stash) deployment on a [Kubernetes](http://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.
+
+## Prerequisites
+
+- Kubernetes 1.5+ 
+
+## Installing the Chart
+To install the chart with the release name `my-release`:
+```bash
+$ helm install stable/stash --name my-release
+```
+The command deploys Stash operator on the Kubernetes cluster in the default configuration. The [configuration](#configuration) section lists the parameters that can be configured during installation.
+
+> **Tip**: List all releases using `helm list`
+
+## Uninstalling the Chart
+
+To uninstall/delete the `my-release`:
+
+```bash
+$ helm delete my-release
+```
+
+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 Stash chart and their default values.
+
+
+| Parameter                | Description                                                       | Default            |
+| ------------------------ | ----------------------------------------------------------------- | ------------------ |
+| `replicaCount`           | Number of stash operator replicas to create (only 1 is supported) | `1`                |
+| `operator.image`         | operator container image                                          | `appscode/stash`   |
+| `operator.tag`           | operator container image tag                                      | `0.3.0`            |
+| `operator.pullPolicy`    | operator container image pull policy                              | `IfNotPresent`     |
+| `pushgateway.image`      | Prometheus pushgateway container image                            | `prom/pushgateway` |
+| `pushgateway.tag`        | Prometheus pushgateway container image tag                        | `v0.4.0`           |
+| `pushgateway.pullPolicy` | Prometheus pushgateway container image pull policy                | `IfNotPresent`     |
+| `rbac.install`           | install required rbac service account, roles and rolebindings     | `false`            |
+| `rbac.apiVersion`        | rbac api version v1alpha1\|v1beta1                                | `v1beta1`          |
+
+
+Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example:
+
+```bash
+$ helm install --name my-release --set image.tag=v0.2.1 stable/stash
+```
+
+Alternatively, a YAML file that specifies the values for the parameters can be provided while
+installing the chart. For example:
+
+```bash
+$ helm install --name my-release --values values.yaml stable/stash
+```
+
+## RBAC
+By default the chart will not install the recommended RBAC roles and rolebindings.
+
+To determine if your cluster supports this running the following:
+
+```console
+$ kubectl api-versions | grep rbac
+```
+
+You also need to have the following parameter on the api server. See the following document for how to enable [RBAC](https://kubernetes.io/docs/admin/authorization/rbac/)
+
+```
+--authorization-mode=RBAC
+```
+
+If the output contains "beta" or both "alpha" and "beta" you can may install with enabling the creating of rbac resources (see below).
+
+### Enable RBAC role/rolebinding creation
+
+To enable the creation of RBAC resources (On clusters with RBAC). Do the following:
+
+```console
+$ helm install --name my-release stable/stash --set rbac.install=true
+```
+
+### Changing RBAC manifest apiVersion
+
+By default the RBAC resources are generated with the "v1beta1" apiVersion. To use "v1alpha1" do the following:
+
+```console
+$ helm install --name my-release stable/stash --set rbac.install=true,rbac.apiVersion=v1alpha1
+```
