...everything (boards, cards, rules, etc)...
The rules are readily available on the site that features the board scans.
I haven't found a good resource for card scans. Well in truth I haven't looked yet; they may even also be available on the same site. I'm just using all of the cards from the AH version of the game, and haven't felt like doing a big P&P project for option cards. Generally, we prefer playing without options anyway, but now I'm just wandering off topic
