+# Prometheus Node Exporter
+
+* Installs prometheus [node exporter](https://github.com/prometheus/node_exporter)
+
+## TL;DR;
+
+```console
+$ helm install stable/prometheus-node-exporter
+```
+
+## Introduction
+
+This chart bootstraps a prometheus [node exporter](http://github.com/prometheus/node_exporter) deployment on a [Kubernetes](http://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.
+
+## Installing the Chart
+
+To install the chart with the release name `my-release`:
+
+```console
+$ helm install --name my-release stable/prometheus-node-exporter
+```
+
+The command deploys node exporter on the Kubernetes cluster in the default configuration. The [configuration](#configuration) section lists the parameters that can be configured during installation.
+
+## 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.
+
+## Configuration
+
+The following table lists the configurable parameters of the Node Exporter chart and their default values.

+
+```console
