July 2018 - v0.2 is released.

This was an interesting process for me. I had never done an ESP8266 project before, and at the time I was just starting to learn Git and GitHub as well. This code ran fairly reliably on my garage door for the last 12 months or so. This is just a minor refresh, no major changes in functionality. Added comments and cleaned up some of the unneeded files in the repo.
