How Do You Submit Maps?

I know how to submit mods, works fine. But how exactly do you submit maps? I tried compressing the folder, but it didn’t work. I seem to be forced to use the steam workshop for AOE 2 2013 for my DE maps.

I can’t find any guides or anything to how exactly to do it. A Youtube video would be really nice.

I have kind of had submitted maps, but the map itself would not download, so I was forced to delete them due to the download not working. When I sub to other maps it takes seconds, but my download never finishes.
