Follow these simple steps to publish your Proofbound book on Amazon Kindle Direct Publishing (KDP)
Proofbound generates two important files, visible in your "My Books" dashboard:
Download both files to your local computer. You'll need to upload them to the Amazon Kindle Direct Publishing site.
Go to kdp.amazon.com and follow the instructions to create an account.
At the top of the KDP main page, click "Create new title or series."
Select "Paperback"
(Do not select Kindle ebook—that is a separate process we'll support later.)

Now enter the basic details about your book: title, author, etc.
Say yes to "I own the copyright and I hold necessary publishing rights."
Should be Amazon.com. (Canadian and other non-US users might have a different marketplace, but so far we haven't tested these.)
Enter appropriate categories and keywords. You'll need to choose at least one (e.g., "Health and Fitness / General").
Select "Release my book for sale now" and click "Save and Continue."
Select "Get a free KDP ISBN". You will need to assign an ISBN.
Answer "AI-Generated Content" truthfully. Amazon uses this information for their internal marketing purposes. It won't affect how the book is published.

Upload your manuscript

Preview will also let you double-check the rest of your manuscript and even download a proof copy.
There shouldn't be any errors. If there are, please let us know at [email protected].
The rest of the KDP publishing workflow should be self-explanatory. You choose your pricing and the markets where you want the book to be sold.
At this point, you may want to order a not-for-resale draft copy. It will only cost a few dollars, plus a reasonable shipping charge that will have it in your hands within days.
Enjoy!
