We use the Arma Launcher for mods.
Once downloaded launch steam then Arma 3 your Arma 3 dashboard will come up. Select the Mods tab, click on the the Preset drop down and then click import at the bottom. Select the HTML file that you downloaded. The launcher will ask to load the files your are missing, once loaded you are ready to play. Make sure you launch the game using that mod set.
