A THREAD FOR NEWCOMERS!

I clearly stated that I read it, but I didn't understand everything, and I had some questions, but you keep giving me the same link. Specifically: 1) I have the complete collection of Heroes version 4.0.0, and there is no RMG text file in the data folder. If I add one, will the template work? 2) How are the templates deciphered? For example, 2SM4d? 3) How do I use the template? That is, I put the document in the data folder, then I go into Heroes, create a map, and it creates it for me according to the template? If the template is, for example, for a small map, should I create a small map? And if I create a large map, will the template still work?
