+Make sure you have this in your @uref{http://www.gnu.org/software/emacs/manual/html_node/emacs/Init-File.html, init file} (usually `~/.emacs`). If you already have @code{custom-set-variables}, merge its contents:

+(custom-set-variables
+ ;; custom-set-variables was added by Custom.
+ ;; If you edit it by hand, you could mess it up, so be careful.
+ ;; Your init file should contain only one such instance.

+@code{haskell-mode} supports GNU Emacs versions 23, 24 and upcoming 25
+(snapshot).

+@code{haskell-mode} is available from @uref{http://stable.melpa.org,melpa-stable (releases)} and @uref{http://melpa.org, melpa

+Other means of obtaining `haskell-mode` include
+@uref{https://github.com/dimitri/el-get, el-get},
+@uref{https://github.com/bbatsov/prelude, Emacs Prelude}) and @uref{https://packages.debian.org/search?keywords=haskell-mode, Debian package}.
+
+Emacs23 requires an the use of @code{cl-lib}.  cl-lib.el can be found in
+the tests/compat directory.  Copy cl-lib.el to your emacs
+directory, e.g. ~/.emacs.d directory and put
+
+@lisp
+(add-to-list 'load-path "~/.emacs.d/")
