Installing Mods in Arma 3

We need the WorkshopID for this. You can find it in the link.
As an example, we will use the mod CBA (Community Based Addons).

The ID for CBA is: 450814997.

Basic Mode

If your Arma 3 configuration is in Basic Mode, the WorkshopIDs need to be entered under Mod Settings in the field Mods (Automatic Installation via Steam Workshop).
If you have multiple mods, separate the WorkshopIDs with semicolons.
It would look like this: WorkshopID1;WorkshopID2;WorkshopID3;

Advanced Mode

In Advanced Mode, you will find the field Mods (Automatic Installation via Steam Workshop) under the Commandline section.
The mods should be entered here following the same rules as in Basic Mode.
