You're talking about the grossly-misnamed (since large portions of it do not contain any questions) OpenBSD FAQ, which is where guide and tutorial stuff is to be found.
BSDs (and some others) come with variously-named Handbooks. OpenBSD has the aforementioned. FreeBSD has a Handbook. So do DragonFly BSD, NetBSD, and others. They are distinct from the user manuals, which are the reference doco. They are, indeed, hyperlinked. Already.
I'm not talking about any specific guides or manuals, but yes the OpenBSD FAQ, FreeBSD Handbook, etc are the sort of manuals i am talking about. But those are not made in manpage format and at least the OpenBSD FAQ HTML pages seem to be edited by hand. And since those are in HTML (at least the OpenBSD one, i didn't look into the others) they lack the indexing and ebook-like reading features that something like info provides (e.g. there are no browsing links - there used to be a pseudostandard with special <link> tags, but it was only ever supported by classic Mozilla/SeaMonkey and it never caught on).
EDIT: i see some of those are authored in DocBook but still info files can in theory be written in DocBook too. The main focus of my comments here is the end user format and viewer capabilities, not the authoring format (and honestly i'm not a big fan of info format with its hardcoded text formatting).
