   Guile-sdl2 uses the standard GNU build system, so installation

 * Developing
 
   To build the source code from a Git checkout, run the following:
 
-  # ./bootstrap
-  # ./configure
-  # make
+  #+BEGIN_SRC sh
+    ./bootstrap
+    ./configure
+    make
+  #+END_SRC
 
   To start a Guile REPL with a pre-configured load path for using
   guile-sdl2, use the =pre-inst-env= script:
 
-  # ./pre-inst-env guile
+  #+BEGIN_SRC sh
+    ./pre-inst-env guile
+  #+END_SRC
 
   GNU Guix users may create a development environment with all of the
   necessary dependencies by running the following command:
 
-  # guix environment -l guix.scm
+  #+BEGIN_SRC sh
+    guix environment -l guix.scm
+  #+END_SRC
+
+  In order to configure the proper library locations for Guix-based
+  builds, the configure script should be invoked like so:
+
+  #+BEGIN_SRC sh
+    ./configure --with-libsdl2-prefix=$(guix build sdl2) \
+                --with-libsdl2-image-prefix=$(guix build sdl2-image) \
+                --with-libsdl2-ttf-prefix=$(guix build sdl2-ttf) \
+                --with-libsdl2-mixer-prefix=$(guix build sdl2-mixer)
+  #+END_SRC
