 This project is focused on making it easy to set up a standardized, scalable, secure Kubernetes environment that can host **multiple instances** of [Open edX](https://www.openedx.org). See [Motivation](#motivation) below.
 
 Specifically, this repository contains:
+
 * A Helm Chart that can install necessary shared resources into your cluster (a load balancer / ingress controller, autoscaling infrastructure, monitoring tools, databases, etc.)
 * A [Tutor](https://docs.tutor.overhang.io/) plugin that configures Tutor to build images that will use the shared resources deployed by the Helm chart.

 Many Open edX providers and users have a need to deploy multiple instances of Open edX onto Kubernetes, but there is currently no standardized way to do so and each provider must build their own tooling to manage that. This project aims to provide an easy and standardized approach that incorporates industry best practices and lessons learned.
 
 In particular, this project aims to provide the following benefits to Open edX operators:
+
 * **Ease of use** and **rapid deployment**: This project aims to provide an Open edX hosting environment that just works out of the box, that can be easily upgraded, and that follows best practices for monitoring, security, etc.
 * **Lower costs** by sharing resources where it makes sense. For example, by default Tutor's k8s feature will deploy a separate load balancer and ingress controller for each Open edX instance, instead of a shared ingress controller for all the instances in the cluster. Likewise for MySQL, MongoDB, ElasticSearch, and other resources. By using shared resources by default, costs can be dramatically reduced and operational monitoring and maintenance is greatly simplified.
-  - For setups with many small instances, this shared approach provides a huge cost savings with virtually no decrease in performance.
-  - For larger instances on the cluster that need dedicated resources, they can easily be configured to do so.
+  * For setups with many small instances, this shared approach provides a huge cost savings with virtually no decrease in performance.
+  * For larger instances on the cluster that need dedicated resources, they can easily be configured to do so.
 * **Scalable hosting** for instances of any size. This means for example that the default configuration includes autoscaling of LMS pods to handle increased traffic.
 * **Flexibility**: this project aims to be "batteries included" and to support setting up all the resources that you need, with useful default configurations, but it is carefully designed so that operators can configure, replace, or disable any components as needed.
