## What is Copyleft?
Copyleft is a strategy of utilizing copyright law to pursue the policy goal
of fostering, encouraging the equal and inalienable right to copy, share,
modify and improve creative works of authorship. Copyleft (as a general
term) describes any method that utilizes the copyright system to achieve the
aforementioned goal. Copyleft as a concept is usually implemented in the
details of a specific copyright license, such as the GNU
[General Public License](http://www.gnu.org/copyleft/gpl.html) and the
[Creative Commons Attribution Share Alike License](http://creativecommons.org/licenses/by-sa/4.0/).
Copyright holders of creative work can choose and implement these licenses
for their own works unilaterally to build communities that share those
creative works.
