I got it in a PDF bundle but not the physical product.
IIRC, there's no information about character creation (just the pregens). Oddly, the pregens start at level 4, so it's a Starter Set that isn't for new players. I'm saying this from the perspective of someone who has the 3 Core Books of A5E and just started my first campaign of A5E for a group of relatively experienced 5E players.
There is enough differences in the first three levels of A5E from regular 5E that I would never drop new players in the system at a level higher than 1 (Destiny, Backgrounds, Origin Traits, Knacks, Skill Specializations, Combat Maneuvers, etc.)
The three adventures contained are each about 10 pages. All three cover levels 4-5.
I think of it as a "system sampler," with the books maybe more akin to a Free RPG Day product. That said, we're loving A5E as a system and the Core books are amazing.
