Want Information or Tutorial on Aimbots

So I met someone in a game a few hours ago with an aimbot that was completely owning the aimbot I was using, no matter what settings I used, I was always being countered, I ended up adding this person as a friend and asking him what he was using. He said he was using some china-made aimbot so I assume it is a paid aimbot. The one I am using works great but I mostly like using hacks to counter other people's hacks and this aimbot I am using certainly is not doing that job very well. I was wondering if someone could post a specific tutorial on how to make a great aimbot, but I am not quite sure what the difference would be in 1 aimbot being better than the other and I would not mind learning how to make one myself if given the proper instructions and guides as to what to do.
