How do I change the territory system to the Flag's system?

Simply put I was wondering how you change the default territory's to the more PVP focused flag based territory system I see active on some servers. Been trying for a while now to know success so I thought it'd be easier to come make a numpty of myself in public in the hopes someone can help :P
