Umm? the rules are similar to the football league? It's basically the football league with a rule missing? Do you know about the football league?
You play an away game and a home game. Win points for winning dont get points for losing? the rule that is missing is the 1 point for a draw. You play each clan twice (H/A) the top 3-4 clans at the end of the league go to the champions league .....etc etc
Like I said it was simple. Can't be arsed doing it now. I would have done it before but got no interest.
