+#+TITLE: Guix and GuixSD Logotypes
 
-The SVG files in this directory are the original logotypes of the GNU Guix
-package manager and the Guix System Distribution (GuixSD).  The logos are
-available for different media: screen, print, etc. For example, the
-"GuixSD.svg" file contains the logo with colors in a range appropriate for
-computer screens (RGB); "GuixSD-print.svg" contains the logo with colors in a
-range appropriate for printing.
+* Introduction
 
+The SVG files in this directory are the original logotypes of the GNU
+Guix package manager and the Guix System Distribution (GuixSD).
 
+Each file contains color, black and white, and other variants of a
+logo.  Open the SVG files with Inkscape to see which variant is better
+for your needs.
 
-Copying
--------
+The logos may be available for different media: screen, print,
+etc. For example, the "GuixSD.svg" file contains the logo with colors
+in a range appropriate for computer screens (RGB); "GuixSD-print.svg"
+contains the logo with colors in a range generally appropriate for
+printing. For other media, the logos may need to be prepared according
+to the limitations of the printing device.
