+## 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.
