-With the commands above you have built a demo example tha invokes the openGJK library. The library is statically linked and the distance between two bodies is computed and returned. 
+The best source to learn how to use OpenGJK are the examples. They are listed [here](https://www.mattiamontanari.com/opengjk/docs/examples/) for C, C#, Go, Matlab and Python. I aim to publish few more for Julia and Unity.
 
-To learn how to use this library in your project the best place to start is the demo. Look at `main.c` and the other examples. In `examples/c/CMakeLists.txt` you can find how simple is to link using CMake.
