+Openshift cluster autoscaler
+================================
+
+Install the cluster autoscaler
+
+Requirements
+------------
+
+* One or more Master servers
+* A cloud provider that supports the cluster-autoscaler
+
+Role Variables
+--------------
+Check defaults/main.yml
+
+Dependencies
+------------
+
+
+Example Playbook
+----------------
+
+#!/usr/bin/ansible-playbook
+```
+---
+- hosts: masters
+  gather_facts: no
+  remote_user: root
+  tasks:
+  - name: include role autoscaler
+    include_role:
+      name: openshift_cluster_autoscaler
+    vars:
+      openshift_clusterid: opstest
+      openshift_cluster_autoscaler_aws_key: <aws_key>
+      openshift_cluster_autoscaler_aws_secret_key: <aws_secret_key>
+```

+
+Notes
+-----
+
+This is currently experimental software.  This role allows users to install the cluster-autoscaler and the necessary authorization pieces that allow the autoscaler to function.
+
+
+This feature requires cloud provider credentials or a serviceaccount that has access to scale up/down nodes within the scaling groups.
