 * Installing Guix from Guix
 
 You can re-build and re-install Guix using a system that already runs Guix.
 To do so:
 
-  - Install the dependencies (see 'Requirements' above) and build tools using
-    Guix:
+  - Start a shell with the development environment for Guix:
 
-      guix package --install={autoconf,automake,bzip2,gcc-toolchain,gettext,guile,libgcrypt,pkg-config,sqlite}
+      guix environment guix
 
-  - set the environment variables that Guix recommends you to set during the
-    package installation process:
-      ACLOCAL_PATH, CPATH, LIBRARY_PATH, PKG_CONFIG_PATH
+  - Re-run the 'configure' script passing it the option
+    '--localstatedir=/somewhere', where '/somewhere' is the 'localstatedir'
+    value of the currently installed Guix (failing to do that would lead the
+    new Guix to consider the store to be empty!).
 
-  - set the PATH environment variable to refer to the profile:
-      PATH=$HOME/.guix-profile/bin:$PATH
-
-  - re-run the configure script passing it the option
-    `--with-libgcrypt-prefix=$HOME/.guix-profile/'
-
-  - run "make" and "make install"
+  - Run "make", "make check", and "make install".
