How to ‘Set Content’ for Local Files? (as in Estuary)

Hi,
Me, very noob. I’m only a little bit familiar with Estuary skin and there, once I had chosen my sources for movies – in my case, local files on a NAS – I would have to right click the source and select ‘Set Content’ so that it would start scraping my chosen source.

In Aeon Nox, I can’t figure out how to get it to scrape my content? As it is now, I’ve chosen my Video Library but it just shows as a list with no images, description, nothing. Just like a boring Windows Explorer list of files. What am I missing here?

I pretty much went through all the menus I could find but found nothing….help! Confused
