The rules are fairly simple. Each team of five must register on the official site to take part in the Regional Qualifiers, which are July 27th and 28th for European players and August 3rd and 4th for North American players. The actual tournament is on August 31st in Seattle. Both tournaments are single match elimination, with the qualifiers playing for best two out of three and the invitational playing for best three out of five. If you've got a team ready to go, head on over to the official site and get ready to play for the prize.
