 You should now see a falling ball on the screen! Check out the [basic three.js example](https://github.com/pmndrs/cannon-es/blob/master/examples/threejs.html) for the full code.
 
 That's it for the basic example, to learn more about all the different features, head over to the [examples page](https://pmndrs.github.io/cannon-es/)!

+## Supported Shape Collision Pairs
+
+Note that not all shapes can collide with each other as some collision algorithms are not implemented. The table below shows which shapes can currently collide with each other:
