+### Programming Emacs with Elisp
+Emacs can be completely customized and rewritten by using the Emacs-specific
+Lisp programming language named Emacs Lisp (Elisp). The ability to completely
+modify the editor is part of what led to the old joke "a great operating 
+system, lacking only a decent editor". Nevertheless, Elisp is what gives 
+Emacs its text editing power despite the perception that the editor is 
+overkill for working with text.
+
+These tutorials will help you learn the Elisp language and use it to modify
+Emacs for your own purposes.

+  developers that have been using Emacs for a while and want to start
