Ask, and ye shall receive:
It's a Google sheet, and you'll want to save it online in your google docs/drive rather than making an offline copy. That'll allow it to access and make use of the Codex PbP helper, which is basically the script that manages deck and card draws.
It's honor system: there are tons of ways you could cheat if you wanted to. But the sheet does a good job of handling your money, keeping track of your buildings, shuffling your deck, reminding you to make a worker, giving you slots to keep track of patrollers, and drawing your hand.
You have to manually add in and delete heroes as they are summoned/killed (and keep track of which ones can't be summoned yourself), and manually enter all your actions, and manually enter their costs in the costs column (as negative numbers; positives are gains). It'll let you know how much money you have left, though, and carry over floating gold. You have to manually enter in Scav. bonuses, and hit the Draw 1 Card button for Technician bonus.
You have to manually enter your two teched cards into the tech slot at the beginning of your turn, but they'll get automatically included in your discard pile when you hit "Discard/Draw" to end your turn.
Realistically, you can often plan out the whole turn in the spreadsheet, play with various scenarios, then decided what to have teched in at the beginning of the turn after you've typed up how the rest of the turn will go.
Oh, and the sheet will generate a nice template with everything you did in forum-friendly format, so you can copy and paste it directly into your online match's thread.
Good luck; you will make mistakes, but don't be afraid to ask lots of questions! (:
