[docs]PDF manual stub

We'll need a simple, maybe even image/based manual for the whole lot. General assumptions:

• user downloads a small-ish USB/ISO
• then they burn the ISO on USB using something like https://www.balena.io/etcher/
• then they need to connect an ethernet cable to their laptop from their home router (sorry, no easy way to do this through wifi)
• then they boot into ISO/USB, select 'install/image my laptop'
• wait for 45 minutes-ish
• reboot and remove USB key, voila!

Here's how I see this being done:

• grab a spare laptop or Virtualbox
• Follow https://github.com/sokoow/globalhack-laptop-installer/blob/master/README.md , section How do I test this?
• make screenshots or pictures of screens with your phone for the whole process
• upload these pictures to this repo
• make a skeleton of a manual

if someone can record a youtube video, that would be cool also
