Mod tool map creation?

So with the new mod tools support released today has there been any documentation released or anyone who knows how map creation works with these mod tools? I remember when HCE mod tools came out I had to dive into old tutorials and tried exporting a UE4 map as an FBX but could never really get the maps to work under the tools (even with using Blender like the tutorials would show), just curious cause I feel like the more people who know how to make maps the more maps we will see that could be really good maps.
