This is a short guide to self-publishing using Kindle Direct Publishing (KDP) that was put out by KDP. I’m not sure this particular e-book exists any more, though all the information in it will be on the KDP website. There are about a billion (exaggeration, maybe) Kindle books that have taken this information and made their own book, using similar names. I can’t comment on any of them. I’m sure some include helpful tips for increasing your sales and making your product more appealing, and some of those tips are likely much better than others.
This is a straight up guide to using KDP. It covers topics like how to set up an account, what formats are accepted (several) and which is best (HTML), royalty options (there are two, and the lesser royalty allows one greater freedom of pricing one’s book, i.e. if you want to sell it at cut-rate to get some sales volume or if you’re a narcissist who thinks their self-published masterwork is worth $200 USD per copy), and how / when payments are made (varies by EFT [electronic funds transfer] v paper check options.)
This guide provides all the information needed to get your book up on Amazon. However, if you want insight into other topics (how to market your book, covers, etc.) you’ll need to look elsewhere.
If you can find it, I’d recommend this handy guide. But it may be quicker to just go to the KDP website.
