Here is how to tame an argie from a very scared cat player:

Get 3-4 gate ways and put enough distance between them for you to get through but not an argie line them up so it looks like this from a side view |||| next grab 2 gates and put them on both ends of the trap meaning the two on the very outside keep one closed and one open.

To trap: aggro the argie and lead it in the trap then close the open door then escape through the gaps between the gates.

Knockout: use tranq darts or arrows to knock out pay attention to the argies health using a magnifying glass is helpful so you don't kill the argie

Taming: argie is a carnivore so use any type of meat best to use mutton or prime meat or kibble if you have any but normal meat will work.

Uses: carrying medium creatures useful for metal gathering during to high weight

There are many of these traps on YouTube if still confused most YouTube vids of ark will use this trap or others.
