iTunes and My Cloud?

Hi Guys,

I’m a total duh here and need some help. Have about 300gb of music on a USB drive. I want to put it in the ‘Shared Music’ folder on My Cloud. How to I direct iTunes to use this as my library?

Can my wife use her Mac and also play from the same library?

EDIT: Done guys. Can’t delete this [post though.
