+# Node-RED
+
+Flow-based programming for the Internet of Things
+
+## TL;DR;
+
+```console
+helm install stable/node-red
+```
+
+## Introduction
+
+This code is adopted from the [official node-red docker image](https://hub.docker.com/r/nodered/node-red-docker/) which runs the [Node-RED application](https://nodered.org/)
+
+
+## Installing the Chart
+
+To install the chart with the release name `my-release`:
+
+```console
+helm install --name my-release stable/node-red
+```
+## Uninstalling the Chart
+
+To uninstall/delete the `my-release` deployment:
+
+```console
+helm delete my-release --purge
+```
+
+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 Sentry chart and their default values.
+
+| Parameter                            | Description                                | Default                                                    |

+
+Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,
+
+```console
+helm install --name my-release \
+  --set config.timezone="America/New_York" \
+    stable/node-red
+```
+
+Alternatively, a YAML file that specifies the values for the above parameters can be provided while installing the chart. For example,
+
+```console
+helm install --name my-release -f values.yaml stable/node-red
+```
+
+Read through the [values.yaml](values.yaml) file. It has several commented out suggested values.
