Local documentation is forthcoming, but in the meantime, check out the docs at the project that powers this wiki: Wagn Documentation.

I've skinned the menus and condensed them into buttons.  They are, in order from inside to outside:

View, Changes, Options, Related, and Edit.

(I need to redo the icons as CSS sprites so that they react properly straight away.  In the meantime, please wait for any icon you hover the mouse over to highlight before you try clicking.)

I turned the links into icons because, as cards get nested, they tend to run up against the card's title and create an unnatural-looking line split.

Feel free to poke around.
