Lifehacker offers a short guide on how to turn your musings into a finished product in the Amazon Kindle Store:

• Write your book in Microsoft Word and save it as a .doc file. Skip the .rtf and .docx formats. They don’t play nicely with the Kindle.

• Pay attention to how you format your text. Bolding, italicizing, and indenting are no problem, but steer clear of bullets, headers, footers, and fancy fonts.

• Any images you use need to be in .jpeg format with center alignment. Remember that the Kindle can only show images in grayscale.
