+compose_project
+=========
+
+Helps you deploy and update a remote docker-compose project.
+
+Requirements
+------------
+
+Any pre-requisites that may not be covered by Ansible itself or the role should be mentioned here. For instance, if the role uses the EC2 module, it may be a good idea to mention in this section that the boto package is required.
+
+Role Variables
+--------------
+
+`service`: name of the service to be deployed. Currently part of the role templates.
+
+`compose_dir`: Directory which contains all compose services on the target
+
+Dependencies
+------------
+
+
+Example Playbook
+----------------
+
+Including an example of how to use your role (for instance, with variables passed in as parameters) is always nice for users too:
+
+    - hosts: servers
+      roles:
+         - { role: compose_project, service: traefik }
+         - { role: compose_project, service: nextcloud }
