Amazon South Africa: new seller

Hey guys, so Amazon is coming to South Africa between now and next year. It’s the first time that we will have Amazon this side. (Africa) Because it will be new, this presents a big opportunity for sellers.

My question is two fold 1. Where do you suggest one learns everything you need to know to get started selling on Amazon

What advice do you have for sellers starting out, especially ones who have no experience of the platform (Amazon).
