# Grafana Helm Chart

* Installs the web dashboarding system [Grafana](http://grafana.org/)

## TL;DR;

```console
$ helm install stable/grafana
```

## Installing the Chart

To install the chart with the release name `my-release`:

```console
$ helm install --name my-release stable/grafana
```

## Uninstalling the Chart

To uninstall/delete the my-release deployment:

```console
$ helm delete my-release
```

The command removes all the Kubernetes components associated with the chart and deletes the release.
