+About
+-----
+XBMC is an award-winning free and open source (GPL) software media player and
+entertainment hub for digital media. XBMC is available for multiple platforms.
+Created in 2003 by a group of like minded programmers, XBMC is a non-profit
+project run and developed by volunteers located around the world. More than 50
+software developers have contributed to XBMC, and 100-plus translators have
+worked to expand its reach, making it available in more than 30 languages.
 
+While XBMC functions very well as a standard media player application for your
+computer, it has been designed to be the perfect companion for your HTPC.
+Supporting an almost endless range of remote controls, and combined with its
+beautiful interface and powerful skinning engine, XBMC feels very natural to
+use from the couch and is the ideal solution for your home theater.
+
+Currently XBMC can be used to play almost all popular audio and video formats
+around. It was designed for network playback, so you can stream your multimedia
+from anywhere in the house or directly from the internet using practically any
+protocol available. Use your media as-is: XBMC can play CDs and DVDs directly
+from the disk or image file, almost all popular archive formats from your hard
+drive, and even files inside ZIP and RAR archives. It will even scan all of
+your media and automatically create a personalized library complete with box
+covers, descriptions, and fanart. There are playlist and slideshow functions, a
+weather forecast feature and many audio visualizations. Once installed, your
+computer will become a fully functional multimedia jukebox.
