+
+#+BEGIN_QUOTE
+The [[https://github.com/iqbalansari/emacs-emojify][emojify]] package requires Emacs *v24.3* and above. Emacs should be compiled
+with support for *PNG* images to display emojis as images. It is *recommended*
+that Emacs is compiled with *ImageMagick* support. ~emojify~ will use it to
+resize emojis if needed, additionally imagemagick is used to set background
+color for emojis to workaround the bug described in [[https://github.com/iqbalansari/emacs-emojify/issues/7][issue 7]]. However these are
+*completely optional*.
+
+PNG support might require some additional steps to on Windows, you might find
+[[http://stackoverflow.com/questions/2650041/emacs-under-windows-and-png-files][this]] stackoverflow answer helpful.
