+# Hyperledger Composer
+
+[Hyperledger Composer](https://hyperledger.github.io/composer) is a set of tools to aid in the development of Blockchain solutions using the [Hyperledger](https://www.hyperledger.org/) Fabric permissioned blockchain framework.
+
+## TL;DR;
+
+```bash
+$ helm install stable/hl-composer
+```
+
+## Introduction
+
+The deployments included in this chart include a Command-Line Interface (CLI), Playground and REST server.
+
+## Prerequisites
+
+- Kubernetes 1.9+
+- PV provisioner support in the underlying infrastructure.
+- Four K8S secrets containing:
+    - the Composer Blockchain Network Archive to deploy and use
+    - the Composer Connection JSON file, specifying the locations of the
+    - the certificate of the Peer Organisation Admin
+    - the private key of the Peer Organisation Admin (needed to join the channel)
+- A running Hyperledger Fabric network, either on the cluster (e.g. using the `hlf-ca`, `hlf-ord`, `hlf-peer` and optionally hlf-couchdb charts) or elsewhere.
+
+## Installing the Chart
+
+To install the chart with the release name `hlc`:
+
+```bash
+$ helm install stable/hl-composer --name hlc
+```
+
+The command deploys the Hyperledger Composer chart on the Kubernetes cluster in the default configuration. The [Configuration](#configuration) section lists the parameters that can be configured during installation.
+
+### Custom parameters
+
+Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example:
+
+```bash
+$ helm install stable/hl-composer --name hlc --set persistence.enabled=true,presistence.storageClass=azurefile
+```
+
+The above command specifies that we wish to use a persistent volume and use the `azurefile` Storage Class to enable the volume to be shared.
+
+Alternatively, a YAML file can be provided while installing the chart. This file specifies values to override those provided in the defualt values.yaml. For example,
+
+```bash
+$ helm install stable/hl-composer --name hlc -f my-values.yaml
+```
+
+## Updating the chart
+
+When updating the chart, make sure you provide the `rest.config.apiKey`, otherwise `helm update` will generate a new random API key.
+
+```bash
+$ export COMPOSER_APIKEY=$(kubectl get secret --namespace {{ .Release.Namespace }} hlc-hl-composer-rest -o jsonpath="{.data.COMPOSER_APIKEY}" | base64 --decode; echo)
+$ helm upgrade hlc stable/hlf-ca --set rest.config.apiKey=$COMPOSER_APIKEY
+```
+
+## Uninstalling the Chart
+
+To uninstall/delete the `hlc` deployment:
+
+```bash
+$ helm delete hlc
+```
+
+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 Hyperledger Composer chart and default values.

+
+## Persistence
+
+The volume stores the Hyperledger Composer data and configurations at the `/home/composer/.composer` path of the containers.
+
+The chart mounts a [Persistent Volume](http://kubernetes.io/docs/user-guide/persistent-volumes/) at this location. The volume is created using dynamic volume provisioning through a PersistentVolumeClaim managed by the chart.
+
+## Feedback and feature requests
+
+This is a work in progress and we are happy to accept feature requests. We are even happier to accept pull requests implementing improvements :-)
