Plz tell me how to upload my culture mod

[IzumiT]

My understanding of the steps to upload a culture mod as follows, but the mod doesn't appear in the in-game upload menu. I think there must be something wrong in my understanding, so could someone please tell me?
1. make folder "Mods" under "steamapps\common\FantasyMapSimulator\FantasyMapSimulator_Data\StreamingAssets"
2. make "Culture" folder under that "Mods" folder
3. place Culture-mod-set folder, including "StateNames.csv" and "CityNames.csv" under that "Culture" folder
4. then return to the game
5. select "Settings" from under-bar menu, press "Workshop" - "Culture set"
...but when I did that way, nothing appears only "close" button...

Can you take a screenshot of your mod path, and send me the mod-related files so I can try it?

Thank you, but it has fixed.
I had included some kind a "readme" file in that folder,
and after I tried to delete that, the folder appears as a uploadable mod folder!

I'm very happy now, but... I would be happier if I can include explanations, road maps and/or disclaimers into the mod folder itself.
