+# prometheus-nginx-exporter
+
+This chart bootstraps a Prometheus [`Nginx Exporter`](https://github.com/nginxinc/nginx-prometheus-exporter) deployment on a [Kubernetes](http://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.
+
+## Get Repository Info
+
+```console
+helm repo add prometheus-community https://prometheus-community.github.io/helm-charts
+helm repo update
+```
+
+_See [`helm repo`](https://helm.sh/docs/helm/helm_repo/) for command documentation._
+
+## Install Chart
+
+```console
+helm install [RELEASE_NAME] prometheus-community/prometheus-nginx-exporter
+```
+
+_See [configuration](#configuring) below._
+
+_See [helm install](https://helm.sh/docs/helm/helm_install/) for command documentation._
+
+## Uninstall Chart
+
+```console
+helm uninstall [RELEASE_NAME]
+```
+
+This removes all the Kubernetes components associated with the chart and deletes the release.
+
+_See [helm uninstall](https://helm.sh/docs/helm/helm_uninstall/) for command documentation._
+
+## Upgrading Chart
+
+```console
+helm upgrade [RELEASE_NAME] [CHART] --install
+```
+
+_See [helm upgrade](https://helm.sh/docs/helm/helm_upgrade/) for command documentation._
+
+## Configuring
+
+See [Customizing the Chart Before Installing](https://helm.sh/docs/intro/using_helm/#customizing-the-chart-before-installing). To see all configurable options with detailed comments, visit the chart's [values.yaml](./values.yaml), or run these configuration commands:
+
+```console
+helm show values prometheus-community/prometheus-nginx-exporter
