This booklet is nothing else than a bound print out of the official Beginners' Guide in the Arch Wiki which fits neatly in the pocket and can be found here:

So to be honest, I was a little bit disappointed because I expected something else, maybe partly more in depth.
But to this end one can and probably should of course refer to the various articles in the excellent Arch Linux Wiki.
Because the booklet seems to be a direct print out from the rendered HTML it also lacks from maybe an inappropiate type and formatting for a paper volume.
So what is a little annoying in this issue are the ample underlined references to other paragraphs which of course only do make sense as clickable hyperlinks in an HTML (or otherwise marked up) document.
Nevertheless, if you do (occasionally) print out various howtos and install guides like me it has the advantage of serving its contents nicely bound between to covers which can be comfortably perused on e.g. commuter train rides without the need for any electronic equipment or gadgetry.
