 an idea of what is currently available. Stork is in the midst of full development with
 monthly releases, so please check back frequently.
 
+.. note::
+
+   Stork uses Kea API calls from the :ischooklib:`libdhcp_host_cmds.so` and
+   :ischooklib:`libdhcp_subnet_cmds.so` hooks to make changes to Kea's
+   configuration.  Such usage is incompatible with the :ref:`_config-backend`
+   (CB).  Stork does not currently implement support for the
+   :ischooklib:`libdhcp_cb_cmds.so` needed to make changes to CB
+   configuration.  If using the Kea CB, Stork can only be safely used in a
+   "read-only" fashion.  Future versions of Stork will add CB support.
