Here is a post I made awhile back. While I am new at this, I have done a lot of research, and the post got a lot of positive feedback from more experienced members here.
@Racer is very knowledgable on the topic and you will find a lot of information on the forum. I think one of the best things you can do is practice on your own fence, or a family member’s and learn that way. Its what worked for me at least. Hope that helps and feel free to message me with any questions. I will do my best to answer them!
