Installing The Mods
Steam has made installing and managing mods a lot easier for players than methods in the past. With the addition of Mod Collections, you can "subscribe" to a multitude of mods at once with a single click.
With ARK, any mods you have subscribed to are automatically downloaded and installed when you start the game. Look for the white text in the lower-right hand corner for updates.
You can subscribe to all the mods with a single click using the Official Mod Collection.
