Is this the correct information for selling on Amazon? Need a straight answer please!

I've been trying to find out if this How-To Guide on selling on Amazon is the right information I need to start selling things on the website. However I haven't been having much luck. People just ignore the question. I'm getting a tad frustrated. If you can be so kind as to just answer the question and not ignore it or answer it with a question or go off-topic, that would be really helpful.
