I just updated the getting started section:-
Once the program has started and shows AnarchyChess splashscreen, go into the configuration.
Theme should be set to "Figurine" (preferred but 2d) or "Classic Wooden" (3d but knook "piece" is currently a partial rook). Engine has to be set to "" (default should be "dreamer") The engine(s) havent been coded for the new piece yet and the engine can "undo" moves it doesnt recognise.
Go back to main menu and select a new game Games need to be set as Human vs human. Set difficulty Easy and Level 1
Start Game
For the first run do the moves:
e4 d5 exd5 c5 dxc6 f6 cxb7 f5 (alternately Kf7) bxa8=O.
Promotion dialog doesnt have correct image for Knook yet, see dialog text as it says how to promote to knook (rightmost horsey). On the board the Knook should have a K in the middle of the rook piece.
Move Knook as you want.
Quit game, and then start a new game.
If it breaks, please comment with moves so i can replicate locally, Thanks.
