Cinema4D Datasmith documentation

I’m a beginner, and want to start bringing in scenes from C4D into UE4 with the new Datasmith/C4D file support. I have not been able to find much documentation on proper workflow, and am struggling with modifying materials, once I have added a datasmith scene from C4D. I’m also interested in proper worklfow for modifying the C4D scene, and having it properly update in UE4
