Tutorial: Steam Workshop Upload

In this tutorial, you will learn how to upload your own mod to the SteamWorkshop. For this, you need to have a “local mod”, one that has not been installed through the workshop, ie. the one created in the “First Mod”-Tutorial.

Step 1: Find your mod in the Mod Management UI

Start the game into Mod Management UI via Steam Launch Options or by passing the -ModManagementUI commandline flag. Find the mod you want to upload, select it, and click the Upload to Steam Workshop button on the details panel of the mod on the lower right.

Step 2: Preparing Steam Workshop Upload

If this is the initial upload (and not an update to your mod), you will need to request a SteamWorkshop Item ID first:

• Click the Prepare Steam Workshop Item button right at the top.
• After a short time, the button should vanish and be replaced with a long number: This is your mods SteamWorkshop Item ID.

Note

If this is the very first time of you interacting with the SteamWorkshop, you may get a prompt to first agree their to their License. Visit the SteamWorkshop through Steam to do that.

Once you have your SteamWorkshop Item ID, fill out the rest of the details (Description, Tags, Visibility, Image, …).

Step 3: Upload to Steam

Click the big Upload to SteamWorkshop button at the bottom.

After the upload is complete, you should now see a “Steam Workshop” link in your mod’s Details panel.
