I wrote a draft introduction to the i3 spin.
Please review/edit it at https://hackmd.io/@kcwitt/ByvfH-QeY
It is pretty rough, but I wanted to put it out there to see what other
things anybody thinks should be included. For example, I didn't include
anything about changing the background image (because I never changed it
myself since you don't see it much in a tiling window manager).
Once all the issues have been identified and included, it probably needs
a top down re-organization.
