That "official" guix recipes in local repo may be modified.

Revised table:

** Sources of and ways to install packages in guixSD

Notes:
(1) proposed
(2) Recipes obtained this way may be modified by the user. Set up the guix git 
repo as described in the manual (info "(guix) Building from Git"). 
(3) Add <user-dir> to GUIX_PACKAGE_PATH as described in the manual (info 
"(guix) Package Modules")

Trying to help a new user get their bearings. What do you think?
