Servicedesk Plus - Travel instance

Servicedesk Plus - Travel instance

Hi team
I saw in different documentation that is it possible to choose additional instance on Servicedesk, like Travel, Finance etc 
On my Servicedesk ESM I have: Servicedesk, Facility, Human Resources and blank.

How can I add Travel instance? I need to start from a blank template or are there something already made?
