Could you add a diagram showing how castling works in this?

I can later (short on time this morning), and I plan to add diagrams to the website and a video discussing it.

Basically, the rook, assuming the spaces are open and he and the rook havent moved, either moves adjacent to the king (if he isnt already adjacent) and the king moves two spaces around him.
