The guide in the link you posted is fairly straightforward and noob-friendly.
I don't think it can be dumbed down more.
If you can't do it yourself, LocyeV has a
fork claiming service and will claim all your forked coins for you.
I followed the steps listed in the guide but i got stuck on where to insert my addresses and private keys (which i can not trust wallets, services... for it)
so if have an idea on how to do it please advise if not thanks for your reply
