# How To Configure Mods On Your Terraria (tModLoader) Server

Information on how to configure mods using tModLoader Server

Mod configuration allows you to fine-tune how each mod behaves on your server — including changing gameplay mechanics or disabling certain modded features. This is done by editing each mod’s config.json file.

> **Warning:** **Important**:
> Not every mod supports configuration. Once a mod has been loaded onto your server, it will automatically generate a config file if configuration is available. If no file appears, that mod likely doesn’t support custom settings or server-side edits.

### Install tModLoader

tModLoader is built specifically for Terraria, but it installs on your system as its own standalone application. Because of this, it shows up as a separate entry in your Steam library.

1.  Head over to the Steam Store and search for the [tModLoader page](https://store.steampowered.com/app/1281930/tModLoader/).
    
2.  Install tModLoader via Steam.
    

After installation, launch tModLoader from Steam to run Terraria with mods enabled.

### Installing Mods Using tModLoader

Adding mods to Terraria through tModLoader is straightforward. Unlike many other games, you do not need to manually download or upload files, as mods can be installed directly from within the application.

1.  From the Steam library launch **tModLoader**.
    
2.  From the main menu in **tModLoader**, select **Workshop**.

3.  Click **Download Mods** to open the built in mod browser.

6.  Repeat this process for any additional mods you want to use.
    
7.  Return to the **Workshop** menu and open **Manage Mods**.

9.  Restart tModLoader to apply the changes.
    

> **Warning:** **Important Recommendation**: Before continuing, it is best to test your mods in a new single player world. This helps confirm that all selected mods are compatible with each other. If the world fails to load, disable mods one at a time to identify which mod is causing the issue.
