With such a small form factor and USB OTG connectors, many hackers didn't like the idea of adding to the size of the board with an adapter and then tacking on a USB dongle. This recipe shows you how to attach an uncased Wi-Fi adapter to the Raspberry Pi Zero to keep your footprint still small enough to fit a mints tin.
