+# Moodle
+
+[Moodle](https://www.moodle.org) Moodle is a learning platform designed to provide educators, administrators and learners with a single robust, secure and integrated system to create personalised learning environments
+
+## TL;DR;
+
+```console
+$ helm install stable/moodle
+```
+
+## Introduction
+
+This chart bootstraps a [Moodle](https://github.com/bitnami/bitnami-docker-moodle) 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 Moodle 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/moodle
+```
+
+The command deploys Moodle 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 Moodle chart and their default values.
+
+|             Parameter              |              Description               |                   Default                   |

+| `mariadb.persistence.size`         | PVC Storage Request for MariaDB volume | `8Gi`                                       |
+
+The above parameters map to the env variables defined in [bitnami/moodle](http://github.com/bitnami/bitnami-docker-moodle). For more information please refer to the [bitnami/moodle](http://github.com/bitnami/bitnami-docker-moodle) 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 moodleUsername=admin,moodlePassword=password,mariadb.mariadbRootPassword=secretpassword \
+    stable/moodle
+```
+
+The above command sets the Moodle 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/moodle
+```
+
+> **Tip**: You can use the default [values.yaml](values.yaml)
+
+## Persistence
+
+The [Bitnami Moodle](https://github.com/bitnami/bitnami-docker-moodle) image stores the Moodle data and configurations at the `/bitnami/moodle` 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.
