You can now download both the cards for printing and the rules.
Instructions for how to print out the cards are on the last page of the cards PDF. Also here: print out pages 1-3 ten times each (or eleven times each if you want randomizers), and print pages 4-6 once each.
The errata for the cards are very little compared to Dominion: After Dark. Most of Industry's cards are simple, so they don't require too much extra in explanation. However, I did expand on Tariff in the errata--thanks to Clark Allsop for his comment on Part 3, for catching some unintended ways to play Tariff.
If you test out Dominion: Industry and discover any other odd behaviors with cards (or if you need more clarification, leave a comment and I will be sure to correct the errata (or the card itself if necessary).
