+Container Runtime
 =========
 
 Ensures docker package or system container is installed, and optionally raises timeout for systemd-udevd.service to 5 minutes.
 
 container-daemon.json items may be found at https://docs.docker.com/engine/reference/commandline/dockerd/#daemon-configuration-file
 
-Requirements
-------------
+This role is designed to be used with include_role and tasks_from.
 
-Ansible 2.2
+Entry points
+------------
+* package_docker.yml - install and setup docker container runtime.
+* systemcontainer_docker.yml - utilize docker + systemcontainer
+* systemcontainer_crio.yml - utilize crio + systemcontainer
+* registry_auth.yml - place docker login credentials.
 
-Mandator Role Variables
