+# Ghost
+
+[Ghost](https://ghost.org/) is one of the most versatile open source content management systems on the market.
+
+## TL;DR;
+
+```console
+$ helm install stable/ghost
+```
+
+## Introduction
+
+This chart bootstraps a [Ghost](https://github.com/bitnami/bitnami-docker-ghost) 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 Ghost 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/ghost
+```
+
+The command deploys Ghost 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 Ghost chart and their default values.
+
+| Parameter                     | Description                                                   | Default                                                  |

+
+The above parameters map to the env variables defined in [bitnami/ghost](http://github.com/bitnami/bitnami-docker-ghost). For more information please refer to the [bitnami/ghost](http://github.com/bitnami/bitnami-docker-ghost) image documentation.
+
+> **Note**:
+>
+> For the Ghost application function correctly, you should specify the `ghostHost` parameter to specify the FQDN (recommended) or the public IP address of the Ghost service.
+>
+> Optionally, you can specify the `ghostLoadBalancerIP` parameter to assign a reserved IP address to the Ghost service of the chart. However please note that this feature is only available on a few cloud providers (f.e. GKE).
+>
+> To reserve a public IP address on GKE:
+>
+> ```bash
+> $ gcloud compute addresses create ghost-public-ip
+> ```
+>
+> The reserved IP address can be associated to the Ghost service by specifying it as the value of the `ghostLoadBalancerIP` parameter while installing the chart.
+
+Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,
+
+```console
+$ helm install --name my-release \
+  --set ghostUsername=admin,ghostPassword=password,mariadb.mariadbRootPassword=secretpassword \
+    stable/ghost
+```
+
+The above command sets the Ghost 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/ghost
+```
+
+> **Tip**: You can use the default [values.yaml](values.yaml)
+
+## Using an existing database
+
+Sometimes you may want to have Ghost 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/ghost \
+    --set mariadb.enabled=false,externalDatabase.host=myexternalhost,externalDatabase.user=myuser,externalDatabase.password=mypassword,externalDatabase.database=mydatabase
+```
+
+## Persistence
+
+The [Bitnami Ghost](https://github.com/bitnami/bitnami-docker-ghost) image stores the Ghost data and configurations at the `/bitnami/ghost` and `/bitnami/apache` paths 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.
