+This directory contains various samples to illustrate Assimp's
+use in various real-worl environments. Workspaces for all samples
+are bundled in ./workspaces, makesfiles can be found in the 
+respective directories of the samples.
+
+All GL-based samples depend on GLUT. For use with the VS workspaces,
+it's best practice to copy glut right _here_ (./glut/) so the 
+predefined build configuration will find it.
+
+Also note that the VS workspaces links against the DLL version of the library,
+thus you need to build it first (assimp-release-dll) and copy the dll to the
+directory of the sample.
+
+SimpleOpenGL
+
+  A very simple and streightforward OpenGL sample. It loads a
+  model (gets the path to it on the command line, default is dwarf.x)
+  and displays the model as wireframe. Animations and materials are
+  not evaluated at all. This samples uses the C interface to Assimp.
