Beginner Guide?

I only recently found out about this forum. For some reason, the notion of modding Magic 2014 never occurred to me.
I have tried to find the necessary info, but it's all confusing when you are new.
I have 2-3 friends I play with. we always play either standard circle magic online in a private room, or two-headed giant in a private room. That's it. No campaign or random online lobbies.
Can someone please direct me to exactly what needs to be done for us to utilize decks from previous versions and/or custom decks? What to install first, second, etc..
I've read through some of the deck descriptions and they start mention WAD files and having to have certain installers and then I see updates and patch notes galore for each one and have no idea what I need.
I have to learn how to do this so I can walk the other guys through how to do the same, so we can play online.
Thank you for your assistance and pardon the noobness
*Edit* I did look through the wiki too, but it seems to be geared more towards how to code and design/release your own mods. I'm only looking to just use decks from previous versions that you awesome people made and released.
