+# Configuring AWX System (optional)
+
+An AWX setup for managing multiple Matrix servers.
+
+This section is used in an AWX system that can create and manage multiple [Matrix](http://matrix.org/) servers. You can issue members an AWX login to their own 'organisation', which they can use to manage/configure 1 to N servers.
+
+Members can be assigned a server from Digitalocean, or they can connect their own on-premises server. This script is free to use in a commercial context with the 'MemberPress Plus' and 'WP Oauth Sever' addons. It can also be run in a non-commercial context.
+
+The AWX system is arranged into 'members' each with their own 'subscriptions'. After creating a subscription the user enters the 'provision stage' where they defined the URLs they will use, the servers location and whether or not there's already a website at the base domain. They then proceed onto the 'deploy stage' where they can configure their Matrix server.
+
+Ideally this system can manage the updates, configuration, backups and monitoring on it's own. It is an extension of the popular deploy script [spantaleev/matrix-docker-ansible-deploy](https://github.com/spantaleev/matrix-docker-ansible-deploy).
+
+Warning: This project is currently alpha quality and should only be run by the brave.
+
+
+## Other Required Playbooks
+
+The following repositories allow you to copy and use this setup:
+
+[Create AWX System](https://gitlab.com/GoMatrixHosting/create-awx-system) - Creates and configures the AWX system for you.
+
+[Ansible Create Delete Subscription Membership](https://gitlab.com/GoMatrixHosting/ansible-create-delete-subscription-membership) - Used by the AWX system to create memberships and subscriptions.
+
+[Ansible Provision Server](https://gitlab.com/GoMatrixHosting/ansible-provision-server) - Used by AWX members to perform initial configuration of their DigitalOcean or On-Premises server.
+
+## Testing Fork For This Playbook
+
+Updates to this section are trailed here:
+
+[GoMatrixHosting Matrix Docker Ansible Deploy](https://gitlab.com/GoMatrixHosting/gomatrixhosting-matrix-docker-ansible-deploy)
+
+
+## Does I need an AWX setup to use this? How do I configure it? 
+
+Yes, you'll need to configure an AWX instance, the [Create AWX System](https://gitlab.com/GoMatrixHosting/create-awx-system) repository makes it easy to do. Just follow the steps listed in '/docs/Installation.md' of that repository.
+
+
+## Does I need a front-end WordPress site? And a DigitalOcean account? 
+
+You do not need a front-end WordPress site or any of the mentioned WordPress plugins to use this setup. It can be run on it's own in a non-commercial context.
+
+You also don't need a DigitalOcean account, but this will limit you to only being able to connect 'On-Premises' servers.
