For the most part I feel like I "got it" but reading over this in my spare time did solidify my foundation.
and then this
Currenly I'm working my way through this long tutorial, taking my time to understand what we're doing.
My only critique, if you can call it that, is there's a LOT skipped over in the name making it a doable tutorial (already 122 pages) They can't have you make EVERYTHING otherwise it'd take forever so they skip over a lot. That's cool, just leave big gaps to fill in later.
