TITLE: learning $\mathbf{A}^1$-homotopy theory
QUESTION [9 upvotes]: If you wanted to learn $\mathbf{A}^1$-homotopy theory, which sources in which order would you use?

REPLY [5 votes]: Aravind Asok has an entire website devoted to pointing out resources for learning $\mathbf{A}^1$-homotopy theory.  It is organized quite well.  The concept list section of the page has lots of wikipedia-like entries on topics related to $\mathbf{A}^1$-homotopy theory.

REPLY [2 votes]: A book that might be helpful, that is probably mentioned on website above is http://www.amazon.com/Motivic-Homotopy-Theory-Nordfjordeid-Universitext/dp/3540458956/ref=sr_1_1?ie=UTF8&qid=1303257360&sr=8-1
Also, people now call it Motivic instead of $\mathbb{A}^1$ sometimes.
