BI installation guide?

I'm looking for a BI installation guide. I've checked the obvious places:

service.sap.com/bi

service.sap.com/instguides

I thought I had found it in 'instguides' but the link sent me over to 'bi'. And then, alas, I was lost.

Does anyone know where it really is? Did they just create some links that put you in an endless loop?
