Doesn't look like this is being maintained anymore. *** Link here to fork with some fixes ***

Sadly I don't think the original author of this repo is maintaining it any more. As some of the footprints fail DRC checks on current versions of Kicad, I have forked it and added some fixes: https://github.com/Basirk/kicad-ESP8266

If anyone else wants to contribute, please do. I'll happily accept pull requests to the fork, but will be mostly trusting that people know what they're doing because I don't really!

Also note that I think the default Kicad footprint library now contains some ESP8266 modules under RF_Module. These weren't suitable for me as I wanted access to the pins on both sides of the board, and the Kicad version only had single-sided SMD.
