-Helm stores configuration based on the XDG base directory specification, so
+Helm stores cache, configuration, and data based on the following configuration order:
 
-- cached files are stored in $XDG_CACHE_HOME/helm
+- If a HELM_*_HOME environment variable is set, it will be used
-- configuration is stored in $XDG_CONFIG_HOME/helm
+- Otherwise, on systems supporting the XDG base directory specification, the XDG variables will be used
-- data is stored in $XDG_DATA_HOME/helm
+- When no other location is set a default location will be used based on the operating system
 
 By default, the default directories depend on the Operating System. The defaults are listed below:

+# 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.
+
+It also packages the [Bitnami MariaDB chart](https://github.com/kubernetes/charts/tree/master/stable/mariadb) which is required for bootstrapping a MariaDB deployment for the database requirements of the WordPress application.
+
+## 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 table lists the configurable parameters of the WordPress chart and their default values.

+
+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 --name my-release \
+  --set wordpressUsername=admin,wordpressPassword=password,mariadb.mariadbRootPassword=secretpassword \
+    stable/wordpress
+```
+
+The above command sets the WordPress administrator account username and password to `admin` and `password` respectively. Additionally, it sets the MariaDB `root` user password to `secretpassword`.
+
+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)
+
+## Production and horizontal scaling
+
+The following repo contains the recommended production settings for wordpress capture in an alternative [values file](values-production.yaml). Please read carefully the comments in the values-production.yaml file to set up your environment appropriately.
+
+To horizontally scale this chart, first download the [values-production.yaml](values-production.yaml) file to your local folder, then:
+
+```console
+$ helm install --name my-release -f ./values-production.yaml stable/wordpress
+```
+
+Note that [values-production.yaml](values-production.yaml) includes a replicaCount of 3, so there will be 3 WordPress pods. As a result, to use the /admin portal and to ensure you can scale wordpress you need to provide a ReadWriteMany PVC, if you don't have a provisioner for this type of storage, we recommend that you install the nfs provisioner and map it to a RWO volume.
+
+```console
+$ helm install stable/nfs-server-provisioner --set persistence.enabled=true,persistence.size=10Gi
+$ helm install --name my-release -f values-production.yaml --set persistence.storageClass=nfs stable/wordpress
+```
+
+## 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.
+
+## Using an external database
+
+Sometimes you may want to have Wordpress connect to an external database rather than installing one inside your cluster, e.g. to use a managed database service, or use run a single database server for all your applications. To do this, the chart allows you to specify credentials for an external database under the [`externalDatabase` parameter](#configuration). You should also disable the MariaDB installation with the `mariadb.enabled` option. For example:
+
+```console
+$ helm install stable/wordpress \
+    --set mariadb.enabled=false,externalDatabase.host=myexternalhost,externalDatabase.user=myuser,externalDatabase.password=mypassword,externalDatabase.database=mydatabase,externalDatabase.port=3306
+```
+
+Note also if you disable MariaDB per above you MUST supply values for the `externalDatabase` connection.
+
+## Ingress
+
+This chart provides support for ingress resources. If you have an
+ingress controller installed on your cluster, such as [nginx-ingress](https://kubeapps.com/charts/stable/nginx-ingress)
+or [traefik](https://kubeapps.com/charts/stable/traefik) you can utilize
+the ingress controller to serve your WordPress application.
+
+To enable ingress integration, please set `ingress.enabled` to `true`
+
+### Hosts
+
+Most likely you will only want to have one hostname that maps to this
+WordPress installation, however, it is possible to have more than one
+host.  To facilitate this, the `ingress.hosts` object is an array.
+
+For each item, please indicate a `name`, `tls`, `tlsSecret`, and any
+`annotations` that you may want the ingress controller to know about.
+
+Indicating TLS will cause WordPress to generate HTTPS URLs, and
+WordPress will be connected to at port 443.  The actual secret that
+`tlsSecret` references do not have to be generated by this chart.
+However, please note that if TLS is enabled, the ingress record will not
+work until this secret exists.
+
+For annotations, please see [this document](https://github.com/kubernetes/ingress-nginx/blob/master/docs/annotations.md).
+Not all annotations are supported by all ingress controllers, but this
+document does a good job of indicating which annotation is supported by
+many popular ingress controllers.
+
+### TLS Secrets
+
+This chart will facilitate the creation of TLS secrets for use with the
+ingress controller, however, this is not required.  There are three
+common use cases:
+
+* helm generates/manages certificate secrets
+* user generates/manages certificates separately
+* an additional tool (like [kube-lego](https://kubeapps.com/charts/stable/kube-lego))
+manages the secrets for the application
+
+In the first two cases, one will need a certificate and a key.  We would
+expect them to look like this:
+
+* certificate files should look like (and there can be more than one
+certificate if there is a certificate chain)
+
+```
+-----BEGIN CERTIFICATE-----
+MIID6TCCAtGgAwIBAgIJAIaCwivkeB5EMA0GCSqGSIb3DQEBCwUAMFYxCzAJBgNV
+...
+jScrvkiBO65F46KioCL9h5tDvomdU1aqpI/CBzhvZn1c0ZTf87tGQR8NK7v7
+-----END CERTIFICATE-----
+```
+* keys should look like:
+```
+-----BEGIN RSA PRIVATE KEY-----
+MIIEogIBAAKCAQEAvLYcyu8f3skuRyUgeeNpeDvYBCDcgq+LsWap6zbX5f8oLqp4
+...
+wrj2wDbCDCFmfqnSJ+dKI3vFLlEz44sAV8jX/kd4Y6ZTQhlLbYc=
+-----END RSA PRIVATE KEY-----
+````
+
+If you are going to use Helm to manage the certificates, please copy
+these values into the `certificate` and `key` values for a given
+`ingress.secrets` entry.
+
+If you are going are going to manage TLS secrets outside of Helm, please
+know that you can create a TLS secret by doing the following:
+
+```
+kubectl create secret tls wordpress.local-tls --key /path/to/key.key --cert /path/to/cert.crt
+```
+
+Please see [this example](https://github.com/kubernetes/contrib/tree/master/ingress/controllers/nginx/examples/tls)
+for more information.
