It's time to pull together the last three series that I have been writing - How to customize your Linux desktop, Experiments with the i3 Window Manager, and Kali Linux. I had originally planned to create an i3 desktop for the Raspberry Pi, but I decided against that (see below for an explanation). I hope that it will be more interesting and more useful to install i3 on Kali Linux.
Warning! Geek Alert! The following "How-to" post is long on technical details and short on pretty pictures and graphics. It even includes manual editing of a configuration text file (gasp!) rather than a point-and-click GUI. If that kind of thing makes you uncomfortable, bail out now!
