 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.

 Testing
 -------
 
-All server playbooks have a corresponding [molecule](https://molecule.readthedocs.io/) test scenario under [`molecule`](molecule).
+We test the playbooks here on Rocky Linux 9 platform via [Ansible Molecule](https://molecule.readthedocs.io/), see test scenarios under [`molecule`](molecule).
+
+The main components of the playbooks (roles) are being independently tested on both Rocky Linux 9 and Ubuntu 22.04. See e.g. [ome.omero_server role](https://github.com/ome/ansible-role-omero-server/tree/master/molecule).
