Seems like that is just a different organization of existing content. If you want to put a getting started/users guide here that calls out to the quick starts and other content that seems fine.
Should Teiid have a Users Guide? This might help lead a user as to where to start, where to find the pieces on what's needed to integrate a data source (i.e.., translator and resource adapter). I realize part of the getting started guide does this, but a user's guide seems more appropriate.
