The license NDWiki uses grants free access to our content in the same sense that free software is licensed freely. This principle is known as copyleft. NDWiki content can be copied, modified, and redistributed so long as the new version grants the same freedoms to others and acknowledges the authors of the NDWiki article used (a direct link back to the article is generally thought to satisfy the attribution requirement). NDWiki articles therefore will remain free under the GFDL and can be used by anybody subject to certain restrictions, most of which aim to ensure that freedom.
To this end, the text contained in NDWiki is copyrighted (automatically, under the Berne Convention for the Protection of Literary and Artistic Works by NDWiki contributors and licensed to the public under the GNU Free Documentation License (GFDL).

Contributors' rights and obligations
If you contribute material to NDWiki, you thereby license it to the public under the GFDL.
In order to contribute, you must be in a position to grant this license, which means that either
- you hold the copyright to the material, for instance because you produced it yourself, or
- you acquired the material from a source that allows the licensing under GFDL, for instance because the material is in the public domain or is itself published under GFDL.
In the first case, you retain copyright to your materials. You can later republish and relicense them in any way you like. However, you can never retract the GFDL license for the copies of materials that you place here; these copies will remain under GFDL until they enter the public domain.
In the second case, if you incorporate external GFDL materials, as a requirement of the GFDL, you need to acknowledge the authorship and provide a link back to the network location of the original copy.
