Documentation for the collection.
I like subtrees of other roles. sometimes i'll fork role and then push changes back up
example for zfs role
git subtree -P roles/zfs add https://github.com/mrlesmithjr/ansible-zfs.git master --squash
ROLE_NAME=zfs
REPO=https://github.com/mrlesmithjr/ansible-zfs.git
REPO_BRANCH=master
git subtree -P roles/${ROLE_NAME} add ${REPO} ${REPO_BRANCH} --squash
