Using r2modman


For Linux and Steam Deck users, please follow the Linux instructions.

This guide will run you through installing and using r2modman to install and play with mods that are available through Thunderstore. Using a mod manager like r2modman allows you to update and play with the latest versions of the mods with ease as the manager does all of that for you!

Installing r2modman

First things first, download r2modman from its GitHub page.

For Windows, you would want to get r2modman-Setup-VERSION.exe or r2modman-VERSION.exe. The former installs the mod manager to your system, while the latter simply runs r2modman without any sort of installation. Simply run the installer or the program in order to open r2modman.

In order to download, simply click the links as shown below and run the program you just downloaded.
