I've put in several on separate properties for our dogs. Pretty simple. The hardest part is burying the wire. But depending on where you put it, you may not even need to do that. A lot of my runs were through woods where I just placed it on the ground. A few years of leaf fall covers it just fine.
The biggest issue is making sure you or others don't cut the wire while digging in the area at a later date. Not that it's ever happened to me
