The experiemental build is probably harder than the stable. The source is not for people who are only looking to play the game.
You could check out the guide in my sig, that is up to date with the stable. But its already out of date with the experiementals. Itd be a fulltime job keeping it up to date with the experimentals.
It does assume you have a basic familiarity with the game, but you can look all the stuff up and ask us.
