The Kali Nethunter Pages Directly States Install Directions Are Included With Images, WHERE?

Hello All,

Using a MAC and downloaded several imgs, one for OPO and both available for the Nexus 7.

Per the Kali Nethunter page, "Our freely downloadable images come with easy to follow installation and setup instructions to get you up and running in no time at all."

So on the MAC I've gone ahead and UNZIPPED the imgs that I downloaded but all I get is more folders within folders and I see no install directions.

What am I missing?

please advise,
