How to Add Workshop Mods to Your Arma Reforger Server

There are two ways to add Workshop mods to your Arma Reforger server: our HH Mod Manager (recommended), which lets you browse and install mods straight from the panel, or editing serverconfig.json by hand.

Method 1: HH Mod Manager (Recommended)

1. Log in to the Game Control Panel and select your Arma Reforger server.
2. Stop your server. Reforger only reads serverconfig.json when the server starts, so mods should be added, updated or removed while it's stopped.
3. Click the HH Mod Manager icon.
4. Open the Browse Workshop tab. Search for a mod by name, or use the type filter and sort options (Popular, Newest and so on) to look through the Workshop. Click More Info to see a mod's Workshop page.
5. Click Add on the mod you want.
6. A window will show any other mods it requires. Leave Also add required dependencies automatically ticked so they're added too, then click Add to Server.
7. Repeat for any other mods, then start your server.

Managing Your Mods

The Installed Mods tab lists every mod on your server. From there you can:

• Check for Updates to see which mods have a newer version on the Workshop.
• Update selected to update the mods you've ticked.
• Pin Version to keep a mod on a specific version. Mods that aren't pinned show (auto-update) and always use the latest version.
• Update All Pinned to move all your pinned mods to their latest version in one click. Untick Incl. in Update All on any mod you want it to skip.
• Remove selected to remove the mods you've ticked.

As with adding mods, stop your server before updating or removing mods, then start it again afterwards.

Note: If a mod comes with a custom scenario, see our guide on How to Add Workshop Scenarios to Your Arma Reforger Server.

Method 2: Editing serverconfig.json Manually

Each mod needs its ID, name and version. You can find these on the mod's page on the Arma Reforger Workshop, or in the ServerData.json file inside the mod's folder if you've installed it in-game on your PC.

1. Log in to the Game Control Panel and select your server.
2. Stop your server.
3. Under Configuration Files, open the Config Editor for serverconfig.json.
4. Find the "mods" section and add an entry for each mod:

"mods": [
    {
        "modId": "MOD_ID_HERE",
        "name": "Mod Name",
        "version": "1.0.0"
    },
    {
        "modId": "SECOND_MOD_ID",
        "name": "Second Mod",
        "version": "1.0.0"
    }
]

5. Separate entries with a comma, with no comma after the last one.
6. Save the file and start your server.
