Guinness/Homebrew kegging

[CardsFan83]

Hello all, long-time lurker here. I've searched the forums for my question, couldn't find anything definitive. Long story short, I'm a relatively new home brewer wanting to get into kegging. I would like to have a small 2 keg setup, where one is available for my current homebrew, and one is Guinness. I'm starting from scratch, so what would be the most efficient way to do this? Thanks for the help!

I'm very new at this myself. Started out with kegging haven't even bottled yet. On a kegeratori have a two tap set up as well with two stouts going. One of them is a guinness clone that came out really well and I get that great head on it without an expensive nitrogen set up. I read this article in brew magazine and it describes everything and is really interesting check it out.
