How can I learn how you did it?

In the thumbnail of Scholar there is, in my opinion, a great layout. A small change here and there and my needs will be met. There is mention of a document/manual. I can't find the document and I don't know where to look for more assistance. I suspect it is at least in part, a Multisite thing as the network does not have everything.
Any help would be greatly appreciated.
