 The default values are currently designed to give a fast and basic approximation of a shape.
 
-If you want as accurate results as possible and don't care if it takes quite a bit longer you can use a small error threshold (-e 0.01) and a high voxel resolution of ten million (-r 10000000) and a relatively high number of convex hulls say 128 (-h 128)
+If you want as accurate results as possible and don't care if it takes quite a bit longer you can use a small error threshold (-e 0.01) and a high voxel resolution of ten million (-r 10000000) and a relatively high number of convex hulls say 128 (-h 128).
+
+Finally you can set the maximum decomposition depth to much higher than the default value of 10. Setting it to say 15 (-d 15) will allow the algorithm to recurse much more deeply into the shape. A higher depth value requires a 64 bit build of the library.
+
+Example: TestVHACD beshon.obj -e 0.01 -d 15 -r 10000000 -r 128
 
 In most cases this may be overkill for your use case but if you have say machined parts with sharp angles, these settings have a better chance of giving a good result.
 
+Note that setting the maximum decomposition depth to 15 will make the tool run a very long time (possibly multiple minutes) but it will likely give the most precise results.
+
+The default value for decomposition depth is currently ten and it goes in powers of two. So the default value considers a maximum of 1,024 hulls but with a depth of 15 it will consider 32,768 convex hull fragments.

 # Porting guide
 
 The new version is a single header file. You simply need to define '#define ENABLE_VHACD_IMPLEMENTATION 1' prior to including 'VHACD.h' in *one* CPP file in your project.
