+# This is an example of a bring your own (byo) host inventory for a cluster
+# with natively hosted, containerized GlusterFS storage.
+#
+# This inventory may be used with the byo/config.yml playbook to deploy a new
+# cluster with GlusterFS storage, which will use that storage to create a
+# volume that will provide backend storage for a hosted Docker registry.
+#
+# This inventory may also be used with byo/openshift-glusterfs/config.yml to
+# deploy GlusterFS storage on an existing cluster. With this playbook, the
+# registry backend volume will be created but the administrator must then
+# either deploy a hosted registry or change an existing hosted registry to use
+# that volume.
+#
+# There are additional configuration parameters that can be specified to
+# control the deployment and state of a GlusterFS cluster. Please see the
+# documentation in playbooks/byo/openshift-glusterfs/README.md and
+# roles/openshift_storage_glusterfs/README.md for additional details.
