+# WordPress
+
+[WordPress](https://wordpress.org/) is one of the most versatile open source content management systems on the market. A publishing platform for building blogs and websites.
+
+## TL;DR;
+
+```console
+$ helm install stable/wordpress
+```
+
+## Introduction
+
+This chart bootstraps a [WordPress](https://github.com/bitnami/bitnami-docker-wordpress) deployment on a [Kubernetes](http://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.
+
+## Prerequisites
+
+- Kubernetes 1.4+ with Beta APIs enabled
+- PV provisioner support in the underlying infrastructure
+
+## Installing the Chart
+
+To install the chart with the release name `my-release`:
+
+```console
+$ helm install --name my-release stable/wordpress
+```
+
+The command deploys WordPress 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 WordPress chart and their default values.
+
+| Parameter                            | Description                                | Default                                                    |

+
+The above parameters map to the env variables defined in [bitnami/wordpress](http://github.com/bitnami/bitnami-docker-wordpress). For more information please refer to the [bitnami/wordpress](http://github.com/bitnami/bitnami-docker-wordpress) image documentation.
+
+Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,
+
+```console
+$ helm install stable/wordpress \
+  --name my-release \
+  --set wordpressUsername=admin \
+  --set wordpressPassword=password  
+```
+
+The above command sets the WordPress administrator account username and password to `admin` and `password` respectively.
+
+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/wordpress
+```
+
+> **Tip**: You can use the default [values.yaml](values.yaml)
+
+## Persistence
+
+The [Bitnami WordPress](https://github.com/bitnami/bitnami-docker-wordpress) image stores the WordPress data and configurations at the `/bitnami` path of the container.
+
+Persistent Volume Claims are used to keep the data across deployments. This is known to work in GCE, AWS, and minikube.
+See the [Configuration](#configuration) section to configure the PVC or to disable persistence.
+
+## Ingress
+
+This chart provides support for Ingress resource. If you have available an Ingress Controller such as Nginx or Traefik you maybe want to set up `ingress.enabled` to true and choose a `ingress.hostname` for the URL. Then, you should be able to access the installation using that address.
