 * 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) using Guix
+  - install the dependencies (see 'Requirements' above) and build tools using Guix. You should have the following packages installed in your user profile:
+    - autoconf
+    - automake
+    - bzip2
+    - gcc
+    - gettext
+    - glibc
+    - guile
+    - ld-wrapper
+    - libgcrypt
+    - pkg-config
+    - sqlite
+
+  - set the environment variables that Guix recommends you to set during the package installation process:
+      ACLOCAL, CPATH, LIBRARY_PATH, PATH, PKG_CONFIG_PATH
+    In addition, set 
+      GUIX_LD_WRAPPER_ALLOW_IMPURITIES="yes, please"
+
   - re-run the configure script passing it the option
     `--with-libgcrypt-prefix=$HOME/.guix-profile/'
+
   - run "make" and "make install"

Thanks, applied!

Note that I wrapped lines, and added a ChangeLog-style commit log (see
‘HACKING’ for details.)
