For the public build (as in the current build), there will be a link on the launcher linking to the game manual. I've not yet put together the public manual for the game, although there is a pre-order version floating around somewhere.
For the public version, it needs to be a short and easily-understood guide to the game explaining the functionality of each screen without going into too much detail. Does anyone want to help draft the text? I can do it, but I'm going to be a bit busy with the other Kickstarter stuff...
