hows farming work

question how are u suspose to farm on cf i saw that video of the other people doing it but its that just like people wanting to do it or just computer,

i don't wonna farm i just wonna know how it works, i rather skill over level

You just get other people like friends or just another pc with cf and make a room and join it then kill your friend/pc how much times you want. Kinda ovbious.

well whats the point in that
