## What this is

DeDRM is a tool for removing DRM. Its creator, Apprentice Alf, deserves our thanks. I’ll show how to set it up with calibre.

## Why this is

I don’t believe in DeDRM. I believe that if I own something, I should have full control over it. I also like being able to read on other devices without arbitrary rules about how I can read them. Plenty of company seem to disagree with me here, but luckily I don’t have to listen to them about this. And if one of them decides to wipe my books for this article, well, I have backups. No thanks to them.

## Requirements

• basic knowledge of the command line
• DRMed books that you want to free.
