+When it is done ``guix.el'' may be configured by requiring a special
+@code{guix-init} file---i.e., by adding the following code into your
+init file (@pxref{Init File,,, emacs, The GNU Emacs Manual}):
 
 @example
 (add-to-list 'load-path "/path/to/directory-with-guix.el")
-(require 'guix-init)

 @end example
 
+So the only thing you need to figure out is where the directory with
+elisp files for Guix is placed.  It depends on how you installed Guix:
+
+@itemize
+@item
+If it was installed by a package manager of your distribution or by a
+usual @code{./configure && make && make install} command sequence, then
+elisp files are placed in a standard directory with Emacs packages
+(usually it is @file{/usr/share/emacs/site-lisp/}), which is already in
+@code{load-path}, so there is no need to add that directory there.
+
+@item
+If you used a binary installation method (@pxref{Binary Installation}),
+then Guix is installed somewhere in the store, so the elisp files are
+placed in @file{/gnu/store/@dots{}-guix-0.8.2/share/emacs/site-lisp/} or
+alike.  However it is not recommended to refer directly to a store
+directory.  Instead you can install Guix using Guix itself with
+@command{guix package -i guix} command (@pxref{Invoking guix package})
+and add @file{~/.guix-profile/share/emacs/site-lisp/} directory to
+@code{load-path} variable.
+
+@item
+If you did not install Guix at all and prefer a hacking way
+(@pxref{Running Guix Before It Is Installed}), along with augmenting
+@code{load-path} you need to set @code{guix-load-path} variable to the
+same directory, so your final configuration will look like this:
+
+@example
+(let ((dir "/path/to/your-guix-git-tree/emacs"))
+  (add-to-list 'load-path dir)
+  (setq guix-load-path dir))
+(require 'guix-init nil t)
+@end example
+@end itemize

 By default, along with autoloading (@pxref{Autoload,,, elisp, The GNU
 Emacs Lisp Reference Manual}) the main interactive commands for
 ``guix.el'' (@pxref{Emacs Commands}), requiring @code{guix-init} will
