 =====
 
-This work in progress.
-The basics of DFFs and many plugins are implemented (at least read&write).
+This library is supposed to be a re-implementation of RenderWare graphics,
+or a good part of it anyway.
+
+It is intended to be cross-platform in two senses eventually:
+support rendering on different platforms similar to RW;
+supporting all file formats for all platforms at all times and provide
+way to convert to all other platforms.
+
+File formats are already supported rather well, although rasters
+as used by TXD files still need some work, especially for PS2.
+
+As for rendering, D3D9 and OpenGL 3 work somewhat well but both still need
+work. Rendering some things on the PS2 worked in the past but the code
+is not maintained, it was only a test.
+
+# Roadmap
+
+* Work on platform independent rendering functions (setting render states etc.)
+
+* Get a solid GL3 driver working
+
+* Make building everything a bit easier
+
+# Building
+
+Edit the makefile(s) and type 'make BUILD=gl3'
