ACI resources

I'm looking for some resources, books, training materials to get up to speed on ACI.

I've had some basic training so it's not completely foreign to me. However, I'm starting a new job in a few weeks where I'll be working with it on a daily basis.

Are the official Cisco training docs the best place to start:

I looked for books on Amazon as well but most I could find have very few reviews, or were cookbooks which isn't what I'm looking for
