Setting up Pi Zero

Hiya Guys,
Sorry if this has been asked before but a quick Google search didn't reveal it for me. I'm wanting a PirateBox setup on my Pi Zero however the official instructions here tell me I need to log into the Pi Zero using SSH through Ethernet to my router. Obviously the Zero does not have an Ethernet connector on it and I don't have a USB Ethernet adapter to hand. Is there any other way to do this without Ethernet?
Cheers

There are scripts in place that will automagically detect a SUPPORTED wifi device, install its driver and configuration and start broadcasting the SSID.

PirateBox Installs:
2x Zsun's (both testing, one with serial interface)
A5-V11 (mostly for OpenWRT testing DIY)
2x RPi Zero's
(one active in car 24/7, gets a lot of hits at Walmart, movie theaters and the mall)
2x RPi3's (both home servers, one Ubuntu custom install along side a ton of other services)
1x RPi2 (currently work server)
