+@code{prettify-symbols-mode} and @code{global-prettify-symbols-mode}
+are two minor modes (@pxref{Minor Modes}) that can display specified
+symbols as composed characters. For instance, in Emacs Lisp mode
+(@pxref{Lisp Eval}), this mode will replace the string ``lambda'' with
+the Greek lambda character.
+
+@findex prettify-symbols-mode
+@vindex prettify-symbols-alist
+When Prettify Symbols mode and Font Lock mode (@pxref{Font Lock}) are
+enabled, symbols are prettified (displayed as composed characters)
+according to the rules in @code{prettify-symbols-alist}, which are
+locally defined by major modes (@pxref{Major Modes}) supporting
+prettifying. To add further customizations for a given major mode,
+you can modify @code{prettify-symbols-alist}. For example:
+
+@example
+(add-hook 'emacs-lisp-mode-hook
+ (lambda ()
+ (push '("<=" . ?≤) prettify-symbols-alist)))
+@end example
+
+@findex global-prettify-symbols-mode
+You can enable this mode locally in desired buffers, or use
+@code{global-prettify-symbols-mode} to enable it for all modes that
+support it.
