Lacks some minimal doc

[ydirson]

It requires quite some dedication today to make sense of this material. The following would IMHO improve tremendously its usefulness:

• a README for each directory -- the one in cacher/ does help, and the format would also benefit from some enhancements (e.g. explain what each qubesctl invocation achieves; use markdown formatting)
• a toplevel README, which would possibly list projects in increasing complexity, and explain shortly what they demonstrate

I think anyone trying to get a grip on salt should start here:

Agreed though with previous comment.
