 # opengfx
 
+OpenGFX is a set of base graphics for OpenTTD and is the result of the 8bpp Graphics Replacement Project.
+OpenGFX is an open source replacement for the original TTD graphics used by OpenTTD. The main goal of OpenGFX therefore is to provide a set of free base graphics which make it possible to play OpenTTD without requiring the (copyrighted) files from the TTD cd. This potentially increases the OpenTTD fanbase and makes it a true free game (with "free" as in both "free beer" and "open source").
+The OpenGFX base graphics set is currently not complete yet, but is already very playable.
