 To get up _BigBlueButton_ up and running the following variables can be configured:
 
-  * `bbb_server_name`:  Set the FQDN hostname that points to the server where _BigBlueButton_ is going to be installed. This is the only mandatory value, the playbook will fail if this variable is not defined.
+  * `bbb_server_names`:  Set the list of FQDN hostnames that point to the server where _BigBlueButton_ is going to be installed. If only a single FQDN is required, `bbb_server_name` can be used instead. Setting either one of these is the only mandatory value, the playbook will fail if neither variable is defined.
   * `bbb_configure_firewall`: Configure local UFW firewall on server (Default: `True`).
   * `bbb_configure_nat`: Configure NAT support for servers behind an external firewall (Default: `False`).
   * `bbb_configure_ssl`: Configure SSL support using _LetsEncrypt_ certificates (Default: `False`).
