I'm not an old dog, but as far as video games are concerned, I'm an *older* dog. It's not hard. Debugging the issue if it doesnt work is one thing, but for 99%+ of people, it works out of the box. The only issue is setting up an account, and choosing your streaming quality, which is experimentation, or calculation, if you know your upload rate.
I'd be happy to assist if you want help.
