## What is copyleft.org?
copyleft.org is a collaborative project to create and disseminate useful
information, tutorial material, and new policy ideas regarding all forms of
copyleft licensing.
This site itself is licensed under a copyleft license, and has received
contributions from experts around the world. Thus, copyleft.org is the
premier "meta-project" of copyleft: it's useful copylefted information all
about copyleft itself!
### The Copyleft Guide and Tutorial
The primary project currently on this site is a tutorial book entitled
[*Copyleft and the GNU General Public License: A Comprehensive Guide and Tutorial*](/guide/).
This guide describes the policy motivations for copyleft, presents a detailed analysis of the text of
various copyleft licenses, and gives examples and case studies of copyleft compliance situations.
### Getting Involved
There are various ways to get involved with this project. The primary
copyleft.org website is a wiki, and we welcome helpful edits and additions.
