Where are the base rules for league play?

By wcsae, in Arkham Horror League

I've read around several places including here and the wiki but I just can't find information on the basic rules of league play. Please help me out here.

Do you just reset the board for each scenario. I assume character carry over, but do they keep their stuff, clues, etc. I was told all of this was up as a pdf somewhere, but for the life of me I just can't find it.

Any help is appreciated.
