Enabling a "compute" shader?

I'm super new to materials. I'm trying to use the "Recompute Tangent" feature on my LOD 0 mesh. (Enabled in the "LOD0 > Sections" rollout). The tooltip for the Recompute Tangent checkbox is:

This feature only works if you enable "Support Skincache Shaders" in the Project Settings. Please note that skin cache is an experimental feature and only works if you have compute shaders.

I've enabled Skincache Shaders in the Project Settings. But after restarting my meshes are all faceted without any smoothing. I've looked around how to create a compute shader but I don't know where to start -- or what a compute shader really is. Is it some kind of checkbox or custom material type?
