 OME production services playbooks
 =================================
 
-**NOTE: We are in the process of migration of the playbooks in this repo to Rocky Linux 9/RHEL 9 OS but at the moment, they function only on CentOS 7 !!**
 These playbooks encapsulate the running of various production servers run by the OME team.
+
+At the moment, only the `ome-demoserver.yml` playbook is available here. This is a playbook for OMERO.demo server on https://demo.openmicroscopy.org OMERO.server and OMERO.web. You can read more about this [OMERO.demo server on our website](https://www.openmicroscopy.org/explore/).
+
+We are in the process of adding more OME team's production playbooks here.

 If you are looking for examples of running your own production OMERO.server see
