Thanks!  I made a few further tweaks here; I changed some of the wording
(hopefully you agree it's better, if not we can do followups).  I also 
noticed we had a <command> bit that was missed in the conversion to markdown.

I've submitted this as https://github.com/ostreedev/ostree/pull/1282
and queued it for merge.

Thanks again!
