Guide which details new power switch board??

[gizmo]

I must surely be missing something really stupid, but I can't find the latest SAIO guide? By that I mean one which details the new power switch board that kite now ships with SAIOs?

I've got v1.1 but that has the on/off switch and mode button 'without' the board, as it was with the original SAIOs?? It doesn't mention the new method. I don't want to hassle kite right now as I'm sure he's very busy with the current run of boards. The GitHub wiki only seems to have v1.1 of the guide?

Can someone point me in the right direction of the new guide or one that details the install of the new board? I'd like to know how it installs and how to attach the mode button correctly to it.
