I believe we want to be able to refer users who have bugs to the Guix
manual sections on Contributing.  In
<https://lists.gnu.org/archive/html/help-guix/2019-07/msg00066.html>,
the contributing instructions in the Guix manual were not understood
properly.  I hope the attached patch could alleviate this a little.

Regards,
Florian

* doc/contributing.texi (Building from Git, Running Guix Before It Is
Installed): Make instructions using Guix come first and clarify which code is
an instruction and which is merely an example.
