How to Install Mods on an Arma Reforger Server

Mods in Arma Reforger are distributed via the integrated Workshop. To use mods on your server, you need to add their mod data to the config.json file.

Step 1: Find Mod Data

There are two ways to find the required mod data (modId, name, version):

Option A: Via the Arma Reforger Workshop

1. Open Workshop
   Open the Arma Reforger Workshop in your browser.

2. Find mod
   Search for the desired mod and open its page.

3. Note values
   Note down the values for Name, ID and Version.

Option B: Via the local ServerData.json

1. Download mod
   Download the desired mod via the in-game Workshop.

2. Open addons folder
   Open the following folder:

   %USERPROFILE%\Documents\My Games\ArmaReforger\addons
   

3. Open ServerData.json
   Open the folder of the desired mod and open the file ServerData.json.

4. Copy values
   Copy the values for id, name and version from the file.

Step 2: Edit config.json

1. Connect via SFTP
   Connect to your server via SFTP and open the file config.json.

2. Add mods
   Find the "mods" entry and add your mods in the following format:

   "mods": [
     {
       "modId": "YOUR-MOD-ID",
       "name": "Mod-Name",
       "version": "1.0.0"
     }
   ],
   

   Example with multiple mods:

   "mods": [
     {
       "modId": "59674C21AA886D57",
       "name": "BetterMuzzleFlashes 2.0",
       "version": "2.0.8"
     },
     {
       "modId": "591AF5BDA9F7CE8B",
       "name": "Capture & Hold",
       "version": "1.0.8"
     }
   ],
   

3. Restart server
   Save the changes and restart the server.

Export Mod Preset from the Game

Alternatively, you can export your mod list directly from the game:

1. Open main menu
   Open Arma Reforger and go to the main menu.

2. Open Mod Preset
   Click the Mod Preset icon.

3. Copy JSON
   Switch to the JSON tab and click Copy to clipboard.

4. Paste into config
   Paste the copied content into the "mods" section of your config.json.
