Document URL: 
https://docs.openshift.com/container-platform/latest/install_config/install/host_preparation.html#configuring-docker-storage

Section Number and Name: 
configuring-docker-storag

Describe the issue: 

In 7.4 we have changed the name of docker-storage-setup to container-storage-setup. As well as introduced support for Overlayfs2

Suggestions for improvement: 
Add information regarding the changes to docker-storage-setup and information on the support of OverlayFS (with steps to set this up as an alternative) 



Additional information:

Is OverlayFS (overlay and overlay2) supported for use with the docker container runtime?
