How to add Resources items for use in Schedule and Reservations (Sharepoint 2013)

Hi all,

I'm new to sharepoint, and now currently trying to explore SP2013.

I found some differences in Resources for Schedule and Reservations. Previously in SP 2010,  I can easily add new resources items by adding it on the resource list.

Where can I do that in SP2013? Found no resource list yet. I need to have it for the Schedule and Reservations entry in calendar.

Thank you so much for your help.
