How do I make an EPUB readable?

Drag the EPUB book from Adobe Digital Editions to your E-Reader. All you'll need to do is drag the title of the file and drop it onto the icon for your E-Reader in the left panel. Once you've done this, the book will transfer to your E-Reader and appear in your library for reading.
