You will learn as you go. What you need most of all is a few good steel pole that you can get into the ground at about 2 feet.
Depending on how much fence you will be putting up, you will probably only need one pole.
Be sure to get a decent charger. do not get a solar one, they are expensive and i think they suck.
Just be sure your wire is insulated from the ground. The fence is using the ground at a point to complete the circuit, some thing that many just think is implied by the instuctions but many really do not realize.
This is why bird can roost on the wire and not get a jolt, they are not in contact with the ground.
I had a BIG ROO that had a BIG COMB and he managed to contact the wire and the ground at the same time.
He got up about a minute later from unconciousness and crowed, silly bird.
