Installation documentation for new Linux users

[bostrt]

We respectfully request that installation of QK be clearly and linearly
laid out for new Linux OS users.

It would be great if, from the standpoint of a machine with Bare Bones
Debian, what apps and dependency apps should be installed in their
logical sequential order.

If such document exist besides the readme on GitHub that we may have
missed.  Excuse us.

QK looks to be a more UX friendly alternative to AUTOKEY on Linux, which
is ... "clunky"

But we are having difficulty getting it to work.

So a S x S 1-pager would be great.

Thank you for your generous work.
