+# Storybook Chart packaged by Indiegogo
+
+## TL;DR
+
+```bash
+$ helm repo add indiegogo https://charts.indiegogo.com
+$ helm install my-release indiegogo/storybook
+```
+
+## Introduction
+
+This chart bootstraps a Storybook deployment on a [Kubernetes](http://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.
+
+## Prerequisites
+
+- Kubernetes 1.12+
+- Helm 3.6.2
+
+## Getting started with default values
+
+To get you started with modifying the default values to your liking/needs, use the below command to grab the latest `values.yaml` file:
+
+```bash
+$ helm show values indiegogo/storybook > values.yaml
+```
+
+## Installing the Chart
+
+To install the chart with the release name `my-release`:
+
+```bash
+$ helm install my-release indiegogo/storybook
+```
+
+The command deploys Storybook on the Kubernetes cluster in the default configuration. The [Parameters](#parameters) 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 uninstall my-release
+```
+
+> NOTE: If you used `-n namespace` when you installed the chart, be sure to use it again when you uninstall the chart, otherwise the associated dependency Kubernetes resources will not be deleted:
+
+```bash
+$ helm uninstall -n namespace my-release
+```
+
+The command removes all the Kubernetes components associated with the chart and deletes the release.
