How to publish and create documentos to adobe digital editions?

Hello guys,

I'm very interested to create "personal" and "exclusive" content for some of my readers. As example, I want to sell them a short book of tips explaining more about a certain subject.

For that reason I'm very interested to create a limited document, with a expiration date or a limited usage. To protect my copyrights.

I know and I already used the Adobe Digital Editions as a reader, but now I would like to use that as a Publisher.

Could you help me to understand better the rules of publishing and more important HOW can I create a document/file that can be used and published through Digital Editions?

Should I have any special program? Or the InDesign is enough?

I hope that I made myself understandable. I tried to find any explanation or tutorial but when people talk about A.D.E they talk only as a READER and no as a PUBLISHER.

Thank you guys a lot!
