Installing your ModsMods in ArmA3 are by default read from two locations;
Installing to the Arma 3 directory.
By default this is located in:
32-Bit - C:\Program Files\Steam\Steamapps\Common\ArmA 3
64-Bit - C:\Program Files (x86)\Steam\Steamapps\Common\ArmA 3
Extract your @mod_folder here. After extraction it should look like this:
...\Steam\Steamapps\Common\ArmA 3\@Mod_folder_1\Addons\[mod files (.pbo & .bisign)]
Installing to the "My Documents\Arma3" folder.
After extraction, your folder setup could than look like this:
C:\Users\[YOURNAME]\Documents\Arma 3\@Mod_folder_2\Addons\[mod files (.pbo & .bisign)]
It is also possible to set custom mod locations. This is best done with a launcher.
If a mod comes with a "userconfig" folder, place it into your Arma 3 main directory so it should look like this:
...\Steam\steamapps\common\Arma 3\userconfigYou may already have a "userconfig" folder from other addons and/or mods in which case it is safe to merge the contents from this archive.
Launching your Mods with Official ArmA3 LauncherUsing the Official BIS ArmA 3 Launcher
To start the launcher click Play on Arma 3 in Steam. You can install mods, create Mod Presets and configure your game startup options.
The BIS Launcher supports Steam Workshop items, as well as local files (e.g. Armaholic™ mod downloads and other non-Steam Workshop mods). For more information on the Official launcher, check the BIS Wiki here.

Right click on the arma3.exe and create a shortcut. Right click on the shortcut, open its properties.
At the end of the target line, paste -mod=@mod_name like this:
"C:\Program Files\Steam\steamapps\common\arma 3\arma3.exe" -mod=@mod_nameand if you want to add multiple mods, separate them with ";"
"C:\Program Files\Steam\steamapps\common\arma 3\arma3.exe" -mod=@mod_name;@mod_name2Click here for more information on Arma 3 startup parameters.
Launch Parameters via Steam
You can add an Arma 3 Startup Parameter to Steam, in order to do so right-click on ArmA 3 and click Properties and then Set Launch Options.
In the window that opens enter in the following:
-mod=@your_mod_folder_nameFor using multiple mods you would then do so like this:
-mod=@mod_name;@mod_name2;@mod_name3;@mod_name4;@mod_name5*NOTE* When launching your game with the Steam Launch Parameters, any mods enabled via this method will activate every time you launch Arma 3 unless you remove/change the entry in the "Set Launch Options" dialogue. If you change mods frequently, it is recommended you use a launcher.
If the above information still does not provide you with enough to learn how to install custom addons and mods you can always ask in our Guide On Installing Mods thread.
