Do you think it is worth to add one line in this section about Building
from Git [1] or this one about Running from Source [2]?

1: <https://guix.gnu.org/manual/devel/en/guix.html#Building-from-Git>
2:<https://guix.gnu.org/manual/devel/en/guix.html#Running-Guix-Before-It-Is-Installed>

All the best,
