What You will need:

You only need Development Tools (It's only a few hundred MB)

-Select Mod Buddy


If you don't have Visual Studio 2013, you may be prompted with 800MB Install (do that).

Create a New File (FILE/New/Project.../)


Select an Empty Mod, and name It however you like (I'd advise to name it the same as your map)


Write something in there...


Delete this .xml file


Create a New Folder and name it Maps


Add existing item


Go to Documents\My games\Sid Meier's Civilization VI\Saves\WorldBuilder
and select your map file

Final steps

Open Properties of your map, right click/ properties
Go to FrontEnd Actions

Add Action, change the ID section to "AddSEAMAP" and the type to "AddWorldBuilderMap"


Go to files tab and click "ADD", then select your map (Mine is called "Global Warming" don't ask) and click OK


Add 3 Custom Properties:
  • Name - "Name"
  • Description - "Your description"
  • Group - StandardMaps

Save the Map (CTRL+SHIFT+S) and build it to check if everything is correct (CTRL+SHIFT+B)

Upload to Steam

Click "Upload" Button Choose your map file from \Documents\My games\Sid Meier's Civilization VI\Mods (Its the .modinfo file) Add your photo and the descrption for the Workshop item
