I finally sat down and wrote the tutorial that I've been meaning to write for quite some time. It's mainly for MY reference, so I don't have to keep writing out the same info and retaking screenshots to show other people, but I definitely want other people to see this. It covers everything from the basics of genetics itself to resources for installing clean hood templates and townifying genetics and clothes.
