How to install mods on your Valheim server (BepInEx and Thunderstore)

Valheim mods are BepInEx plugins from Thunderstore, the same ones r2modman and the Thunderstore app install. The Mods tab installs them with one click.

1. Sign in to the control panel at panel.chicagoservers.co and open your Valheim server.
2. Open the Mods tab. Under Add a mod, find the mod and click Install. BepInEx and the libraries a mod needs (such as Jötunn) are installed with it. For a mod that isn't in the list, paste its Thunderstore link or name under Any other Thunderstore mod and click Install.
3. Restart the server. Mods load when it starts.

• Mods marked server only need nothing from players.
• Most mods must be installed by every player too, in the same version: players use r2modman or the Thunderstore app with the same mods.
• Console players (Xbox, PlayStation 5, Switch 2) can't install mods. On a server with crossplay, use only server only mods, or console players can't join.
• After a Valheim update (such as Valheim 1.0), mods may stop working until their authors update them. Update them on the Mods tab, and players update theirs too.
• A mod's settings are in BepInEx/config on the Files tab, after the server has started with it once.
• Load mods (BepInEx) on the Startup tab: switch it off to start the server without mods (they stay installed).
