+# nginx-ingress
+
+[nginx-ingress](https://github.com/kubernetes/contrib/tree/master/ingress/controllers/nginx) is an Ingress controller that uses ConfigMap to store the nginx configuration.
+
+To use, add the `kubernetes.io/ingress.class: nginx` annotation to your Ingress resources.
+
+## TL;DR;
+
+```console
+$ helm install stable/nginx-ingress
+```
+
+## Introduction
+
+This chart bootstraps an nginx-ingress deployment on a [Kubernetes](http://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.
+
+## Prerequisites
+  - Kubernetes 1.4+ with Beta APIs enabled
+
+## Installing the Chart
+
+To install the chart with the release name `my-release`:
+
+```console
+$ helm install --name my-release stable/nginx-ingress
+```
+
+The command deploys nginx-ingress on the Kubernetes cluster in the default configuration. The [configuration](#configuration) section lists the parameters that can be configured during installation.
+
+> **Tip**: List all releases using `helm list`
+
+## 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 tables lists the configurable parameters of the aws-cluster-autoscaler chart and their default values.

+
+Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,
+
+```console
+$ helm install stable/nginx-ingress --name my-release -f values.yaml
+```
