+**** Documentation
+     [[https://github.com/mmontone/slime-doc-contribs][slime-doc-contribs]] provides two useful SLIME contribs,
+     . Following the installation instructions on GitHub, the first
+     thing to do is clone the repo from GitHub:
+
+     #+begin_src shell :dir ~/src :tangle no
+       git clone --recursive https://github.com/mmontone/slime-doc-contribs
+       #+end_src
+
+     The =--recursive= flag is needed as the repo has
+     submodules.
+
+     The following lines then have to be added to =~/.sbclrc=:
+
+     #+begin_src common-lisp :tangle no
+       (require :swank)
+       (push #p"/home/cdo/src/slime-doc-contribs/" swank::*load-path*)
+     #+end_src
+
+     With that done, the source directory must be added to [[help:load-path][load-path]],
+     and the two contribs must be enabled.
+
+     #+begin_src emacs-lisp
+       (add-to-list 'load-path "~/src/slime-doc-contribs")
+       (add-to-list 'slime-contribs 'slime-help 'slime-info)
+       (slime-setup)
+     #+end_src

 *** Paredit
     =paredit= is generally very useful for balancing parenthesis so we
     want that turned on for all the lisps. Additionally, it's nice to have
