I got an mail from Bohdan at MS IT, kindly pointing out that I should provide you with som links to the official documentation as well. Of course he is right. Here is what is says: "In particular, it will be good to point to TS Gateway Step-by-Step guide, and the TS team blog. Additionally, for those wanting to learn the practical aspects, this one may be useful."
Thanks, Bohdan. 🙂
