So welcome!

Again, we emphasize that we’re taking things a step further as part of our dedication to teaching you how to Think for Glass: we don’t merely want to show you how to write Glassware, we want to show you how to write great Glassware. And as we’ve demonstrated thus far, such a talent for maximizing the platform involves amassing deep knowledge and embracing pragmatism.

So, as this is the first scene in the third act of our three-act play on Thinking for Glass, let’s wax pessimistic for a moment and get some housecleaning duties out of the way first.

This isn’t going to be an exhaustive dissection of the Mirror API’s various method signatures and expected parameters. The online documentation does a fantastic job of that already, and like Glass, is changing all the time. Our goal is to arm you with a weapon that has far more shelf life and help you understand the documentation and the Glass environment.
