+# Redash
+
+[Redash](http://redash.io/) is an open source tool built for teams to query, visualize and collaborate. Redash is quick to setup and works with any data source you might need so you can query from anywhere in no time.
+
+## TL;DR
+
+```bash
+$ helm install stable/redash
+```
+
+## Introduction
+
+This chart bootstraps a [Redash](https://github.com/getredash/redash) deployment on a [Kubernetes](http://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.
+
+## Prerequisites
+
+- At least 3 GB of RAM available on your cluster
+- Kubernetes 1.4+ with Beta APIs enabled
+- PV provisioner support in the underlying infrastructure
+
+## Installing the Chart
+
+To install the chart with the release name `my-release`:
+
+```bash
+$ helm install --name my-release stable/redash
+```
+
+The command deploys Redash 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` deployment:
+
+```bash
+$ helm delete my-release
+```
+
+The command removes all the Kubernetes components associated with the chart and deletes the release.
+
+## Configuration
+
+The following table lists the configurable parameters of the Redash chart and their default values.

+
+Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,
+
+```bash
+$ helm install --name my-release \
+  --set cookieSecret=verysecret \
+    stable/redash
+```
+
+The above command sets the Redash cookie secret to `verysecret`.
+
+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 -f values.yaml stable/redash
+```
+> **Tip**: You can use the default [values.yaml](values.yaml)
