# How to Install Mods on Your Soulmask Server (/docs/soulmask/mod-setup) import { Step, Steps } from 'fumadocs-ui/components/steps'; Soulmask has official Steam Workshop mod support. Mods are added via startup parameters and auto-download when the server starts. Install Mods [#install-mods] Find Workshop mod IDs [#find-workshop-mod-ids] Browse the [Soulmask Steam Workshop](https://steamcommunity.com/app/2646460/workshop/). The mod ID is the number at the end of the Workshop URL: ``` https://steamcommunity.com/sharedfiles/filedetails/?id=3324057706 ^^^^^^^^^^ This is the mod ID ``` Add mods to Startup [#add-mods-to-startup] In the [XGamingServer Panel](https://panel.xgamingserver.com), click **Startup** in the sidebar. Find the **Mods** variable and enter your mod IDs separated by commas (no spaces): ``` 3324057706,3330908154,3332634339 ``` This maps to the startup parameter: `-mod="3324057706,3330908154,3332634339"` {/* Screenshot needed: Startup tab showing mod IDs field */} Restart the server [#restart-the-server] Restart from **Console**. The server downloads the mods automatically on startup. This may take a few minutes depending on mod sizes. Client Requirements [#client-requirements] Players connecting to a modded server **must have the same mods installed**. When a player tries to join without matching mods, they'll be prompted to subscribe to the required Workshop items. Removing Mods [#removing-mods] Remove the mod ID from the **Startup** variable and restart. Be careful — removing mods that added items or NPCs to the world may cause issues with existing saves.
