We will be using a steam workshop collection and an Arma 3 Sync since we think this is the easiest/fastest way to download the addons.
Just make sure you are subscribed to all the add-ons in the collection and have downloaded all the add-ons in the repository and you should be good to go.
If you have any questions about how to use it or install them feel free to join our Teamspeak and we will be happy to help you out.
