+### The adhoc playbook
+
+The adhoc playbook gives flexibility to run any check or a custom group of
+checks. What will be run is determined by the `openshift_checks` variable,
+which, among other ways supported by Ansible, can be set on the command line
+using the `-e` flag.
+
+For example, to run the `docker_storage` check:
+
+```console
+$ ansible-playbook -i <inventory file> playbooks/byo/openshift-checks/adhoc.yml -e openshift_checks=docker_storage
+```
+
+To run more checks, use a comma-separated list of check names:
+
+```console
+$ ansible-playbook -i <inventory file> playbooks/byo/openshift-checks/adhoc.yml -e openshift_checks=docker_storage,disk_availability
+```
+
+To run an entire class of checks, use the name of a check group tag, prefixed by `@`. This will run all checks tagged `preflight`:
+
+```console
+$ ansible-playbook -i <inventory file> playbooks/byo/openshift-checks/adhoc.yml -e openshift_checks=@preflight
+```
+
+It is valid to specify multiple check tags and individual check names together
+in a comma-separated list.
+
+To list all of the available checks and tags, run the adhoc playbook without
+setting the `openshift_checks` variable:
+
+```console
+$ ansible-playbook -i <inventory file> playbooks/byo/openshift-checks/adhoc.yml
+```
+
