 An Ansible role that acts as a companion to the Rookeries project.  The goal of this role is to make deployment of 
 Rookeries simple.  Ideally Rookeries even as a Python WSGI app with this role, should be easier to setup than Wordpress.
 
+This role is a work-in-progress as Rookeries itself is heavily under development.

-Including an example of how to use your role (for instance, with variables passed in as parameters) is always nice for users too:
 
+The simplest way to include the role in your playbook is to base it off the  below configuration.  The crucial
+part is to configure the rookeries_app_config and the app_nginx_hostname (inherited from the nginx-uwsgi-supervisor 
+role).
