 You can still use svn or svn externals using the github git repository: use svn co https://github.com/erwincoumans/bullet3/trunk
 
 The entire collision detection and rigid body dynamics is executed on the GPU.
 
-Requirements:
+## Requirements
+
 A high-end desktop GPU, such as an AMD Radeon 7970 or NVIDIA GTX 680 or similar.
 We succesfully tested the software under Windows, Linux and Mac OSX.
 The software currently doesn't work on OpenCL CPU devices. It might run
 on a laptop GPU but performance is likely not very good.

 Bullet 3.x uses the separating axis test (SAT) between convex polyhedra, testing all vertex - face and edge - edge combinations. For performance it is best to keep the number of edges in a convex polyhedron low, using simple shapes such as a tetrahedron or a box.
 
 The constraint solver currently supports two constraints:
