Ray Gonzales, Lead UX Designer at Zappos, shares his favorite Design System resources. First, when it comes to the "creation" side of things, Invision is a great way to start. They have an entire collection of books on the subject. When it comes to "adoption," Ray mentions Nathan Curtis, who digs deeper behind the scenes at the structures we can use to disseminate our Design Systems. On the other hand, Paul uses the oldest (yet still best) trick in the book: a Google search!
