Does anyone know where i can find info about configuring Win 10 Ent and Direct Access?

We had a Win 8 Direct Access environment setup and working but abandoned it when we abandoned Win 8. I would like to get DA going again with Win 10. The servers etc. are all still in place.

I know DA has had some changes in Win 10. How different is it?

Are there any whitepapers? or sites i can go to that step you through the setup/config?
