OS Deployment Licensing

OS Deployment Licensing

I inherited Desktop Central and was wondering how OS Deployment licensing worked. I see I have the following licensed:

OS Deployment - Add on
 Number of Server Machines :    1
 Deployed Server Machines :    0
 Number of Workstation Machines :    4
 Deployed Workstation Machines :    0
 
Does that mean I can deploy only one Server and one Workstation or does it mean I can only deploy one server and 4 workstations at a time?

Looking to better automate and standardize our workstation deployments for now.
