How to install and activate an Arma3 mod?

2 min readUpdated November 2026

Explanations

In this guide we will show you how to install & activate a mod on your Arma 3 server.

To install a mod, copy & paste it folder on your arma3 server directory. In general, a mod is a folder which got this name: @modname.

You need to respect 2 rules to don't have issues:

  1. No spaces on names

  2. All in lower case

**Note :**The startup script automatically renames the mods, removes spaces from folder names, and removes capitalization. Same thing in the subfolders, but it's better to prepare the bot tree beforehand just in case ^^

Then add the mod name in the management panel, without the @. For a @modname folder, enter modname and it will be taken into account when the server starts.
