AI Goats

Hello everyone! I am trying to get ahead for next breeding season (late 2022), and am interested in AI for my Nigerians. I have 3 does, only 2 which I would like to breed (one will be a first freshener). I have always bred them with a Buck, never AI. I am interested in AI to improve genetics and introduce new genetics. I have some basic knowledge of AI, but unsure about what type of heat, or mucus to look for, or a hormone/cidr procedure. Any help would be appreciated! Thanks in advance!
