I have published one book so far. Using Amazon Kindle Direct Publishing, I was able to publish it in three formats: e-book, paperback, and hardcover. It was extremely easy to use their Kindle Create app to help format an e-book. With Amazon Kindle Direct Publishing, it's super easy plus you control everything. From how much your book costs to the little specifics, including font, size, and the paper material. So, the first step is making an account for their website (after writing your book, lol). It’s super easy and user-friendly. If you have already finished writing your book and it’s ready to publish, your next step is formatting your book. Within the KDP website, there is information on how to format depending on the type. Each type has its own formatting needs. Remember it's your book; everything is your choice. For any book, you will be able to create your cover. The next part is after creating an account, formatting your book, and creating your cover. Within their webs...
Anything and everything that you can think of... but the kitchen sink. Anything you can think of, anything you can dream of: crafts, how-to's, news, information, cute animals, etc.
