+Role Name
+=========
+
+The purpose of this role is to create a backup of your AWX deployment.  This includes:
+  - backup of the postgresql database
+  - secret_key
+  - custom user config files
+  - manual projects
+
+
+Requirements
+------------
+
+This role assumes you are authenticated with an Openshift or Kubernetes cluster which:
+  - The awx-operator has been deployed to
+  - AWX is deployed to via the operator
+
+
+Usage
+----------------
+
+Then create a file named `backup-awx.yml` with the following contents:
+
+```yaml
+---
+apiVersion: awx.ansible.com/v1beta1
+kind: Backup
+metadata:
+  name: awx
+  namespace: my-namespace
+```
+
+Finally, use `kubectl` to create the awx instance in your cluster:
+
+```bash
+#> kubectl apply -f backup-awx.yml
+```
+
+
+
+Role Variables
+--------------
+
+A custom, pre-created pvc can be used by setting the following variables.  
+
+```
+tower_backup_pvc: 'awx-backup-volume-claim'
+```
+
+This role will automatically create a pvc using a Storage Class if provided:
+
+```
+tower_postgres_storage_class: 'standard'
+tower_backup_size: '20Gi'
+```
+
+If a custom postgres configuration secret was used when deploying AWX, it must be set:
+
+```
+tower_postgres_configuration_secret: 'awx-postgres-configuration'
+```
+
+
+Testing
+----------------
+
+You can test this role directly by creating and running the following playbook with the appropriate variables:
+
+```
+---
+- name: Backup Tower
+  hosts: localhost
+  gather_facts: false
+  roles:
+    - backup
+```
