 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.

 This role is designed to work against a modern Ubuntu system.  (Tested on Ubuntu 13.10 and 14.04)  It should 
 theoretically work on older versions of Ubuntu or Debian based systems.

-Including an example of how to use your role (for instance, with variables passed in as parameters) is always nice for users too:
+Example Playbook
+----------------
 
+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).
+         
     - hosts: servers
+      sudo: yes
+      vars:
+          my_rookeries_app_config:
+              rookeries_environment_name: ...
+              ...
       roles:
-         - { role: username.rolename, x: 42 }

 This role depends on the nginx_uwsgi_supervisor role, and hence reuses the variables provided by that role.  See the
