+Along with ``guix.el'', GNU@tie{}Guix comes with ``guix-prettify.el''.
+It provides a minor mode for abbreviating store file names by replacing
+hash sequences of symbols with ``@dots{}'':
+
+@example
+/gnu/store/72f54nfp6g1hz873w8z3gfcah0h4nl9p-foo-0.1

+Once you set up ``guix.el'' (@pxref{Emacs Initial Setup}), the following
+commands become available:

+@table @kbd
+
+@item M-x guix-prettify-mode
+Enable/disable prettifying for the current buffer.
+
+@item M-x global-guix-prettify-mode
+Enable/disable prettifying globally.
+
+@end table
+
+To automatically enable @code{guix-prettify-mode} globally on Emacs

+@example
+(global-guix-prettify-mode)
+@end example
+
+If you want to enable it only for specific major modes, add it to the
+mode hooks (@pxref{Hooks,,, emacs, The GNU Emacs Manual}), for example:
