Usage Instructions is not updated?!

Hi,
I'm trying to install Multi-DB following the usage instructions (here: https://premium.wpmudev.org/project/multi-db/).
But is seems that the instructions in adding DB servers is not updated. The DB server tool (https://premium.wpmudev.org/db-tools/db.php) generate results looks like:
$db_list['0a5']['db_name'] = XXXX';
$db_list['0a5']['db_user'] = 'XXX';
$db_list['0a5']['db_password'] = 'XXXX';
$db_list['0a5']['db_host'] = 'XXXX';

The instructions mentioned that I need to get results looks like:
add_db_server('global', 'dc1', 1, 1,'','111.222.333.444', 'dbname_global', 'username', 'password');
add_db_server('global', 'dc1', 1, 1,'','111.222.333.444', 'dbname_global', 'username', 'password');

Is there any updated usage guide?

Many thanks!
