Skullgirls Update

Hey guys.

I searching lots of different forums and googling quite a bit to try to figure out what I need to do to figure this out, but I figure I'll have the best shot here.

I got Skullgirls on my 3.55 Kmeaw PS3 and as some of you may know lots of fighting games release many patches to balance characters etc. A new Skullgirls patch just came out yesterday and I don't know if I'd have to wait for a pkg to update it or if you guys just update PSN games online. How would I go about getting my Skullgirls updated?

Thanks alot.
