+The easiest way to install =gnuplot-mode= is to directly get it from [[https://elpa.nongnu.org/][NonGNU ELPA]]
+or [[http://melpa.org][MELPA]]. After configuring Emacs to use MELPA, you should be able to install
+gnuplot-mode by typing
 
 : M-x install-package RET gnuplot RET
 
 or do =M-x list-packages= and search for =gnuplot= in the list.
 
-** Using =el-get=
-
-The [[https://github.com/dimitri/el-get.git][el-get]] package includes a gnuplot-mode recipe. So to install
-simply call
-
-: M-x el-get-install RET gnuplot-mode
-
-Alternatively, you can directly place the following in your init file so that
-=el-get= can install and load gnuplot-mode at Emacs start up:
-
-: (el-get 'sync 'gnuplot-mode)
-
-** From source
-
-After fetching the package's source from [[https://github.com/emacs-gnuplot/gnuplot][the homepage]], byte-compile
-the package's files using the =make= command and move the compiled
-=.elc= files to your chosen target directory.
-
 * Configuration
-** Load Path
-
-First of all, make sure that =gnuplot.el= is in your load-path (this is automatic if using a package helper like use-package). To do so manually, add the following snippet in your emacs configuration file
 
-#+begin_src emacs-lisp
-(add-to-list 'load-path "/path/to/gnuplot")
-#+end_src
-
-** Info File
-
-The function =gnuplot-info-lookup-symbol= looks at the Gnuplot info
-file. For that function to work, a =gnuplot.info= file must be placed
-somewhere where info can find it. The following snippet allows you
-to put the =gnuplot.info= any place convenient:
-
-#+begin_src emacs-lisp
-(add-to-list 'Info-default-directory-list "/path/to/info/file")
-#+end_src
-
-** Enable Mode
-
-You can automatically enable =gnuplot-mode= using the snippet below:
-
-#+begin_src emacs-lisp
-(autoload 'gnuplot-mode "gnuplot" "Gnuplot major mode" t)
-(autoload 'gnuplot-make-buffer "gnuplot" "open a buffer in gnuplot-mode" t)
-(setq auto-mode-alist (append '(("\\.gp$" . gnuplot-mode)) auto-mode-alist))
-#+end_src
+=gnuplot-mode= is enabled automatically for =*.gp= files. The function
+=gnuplot-info-lookup-symbol= looks at the Gnuplot info file. For that function to
+work, a =gnuplot.info= file must be available in a directory in
+=Info-directory-list=.
