[GUIDE] How to create your own hero?

Hello everyone, I created my own hero following this guide, but I have a couple of questions:

1. Is it possible (and if so, how) to make this hero selectable in a multiplayer game, just like any other hero?

2. I didn't quite understand the last point about adding the mod's content to the map folder. If I simply put the files from the mod inside the map archive, I don't understand how to set up my hero in the map editor, or am I doing something wrong/not understanding it correctly?

Answer to the first point:
Yes, you can select new heroes in a multiplayer game. In the data archive, there is a folder called sharedgroup, which contains a folder with heroes, and inside it, there is a text file called standartheroes (it contains a list of 8 heroes; you add a link to your hero's file there), and he will be available on maps generated by the map generator. If you want the hero to be available on maps created through the map editor, you need to go into the map file and, at the bottom of the map properties, there are lines called Availableheroes (it will contain a list of 64 heroes; you need to add your hero there), and he will be available for selection in the lobby of that map
