Installation steps come from the developer’s published mod manual at commit c84e688. Check a mod’s own requirements and compatibility notes.
Subscribe through Steam Workshop
Open the game’s Workshop, read the mod description and subscribe to the items you want. The developer’s manual says Workshop subscriptions load on the next launch.
NoteRestart the game, then check Main menu → MOD Manager to confirm the mod is enabled.
Install a local .zedmod file
The manual supports .zedmod files and folder-form mods under Mods/
NoteThe manual says to create the Mods folder if it is missing. Keep the mod’s supplied structure intact.
Enable, disable and troubleshoot
Open MOD Manager from the main menu to enable or disable a mod. If it does not appear, check the sub-folder and the mod’s installation instructions first.
NoteChange one mod at a time when investigating a problem. Test in a separate world so that troubleshooting does not put your main run at risk.
Create your own mod
The documented workflow starts at Main menu → MOD Editor → New. Choose a supported type and import a vanilla item to seed its parameters. The manual then describes editing attributes, textures and localized strings.
NoteUse the item reference for numeric IDs and the developer’s individual type manuals for field definitions.
Use mods in co-op
The full-release announcement says the host’s mods synchronize to joining players. Agree on the collection and versions with your group before starting a long session.
NoteBack up the host world before removing a mod that provides equipment or world objects.
