NixOS Wiki:Copyrights

Contributions to the official NixOS Wiki fall into four broad categories: editing and creating articles, contributing to discussions in a page's discussion page, uploading images that are used in articles, and contributing to the wiki's source code on GitHub.

Creating and editing articles

By contributing to the NixOS Wiki in the form of editing pages on the website, either articles or discussion pages, contributors agree to release their changes under the same license as the wiki's infrastructure repository license, in particular the MIT License. When contributing content to the wiki, editors affirm that they have the legal authority to license their contributed content under the MIT License, either through content ownership, contributing original work, or by contributing content that is already in the public domain. The text of the license is reproduced below:

Contributing to the infrastructure

All contributions to the official NixOS Wiki infrastructure are exclusively handled through the GitHub repository. Thus, any contributions must follow the guidelines set therein.

Contributing images

In general, contributions in the form of file uploads must follow the same copyright policy that governs textual contributions. The only notable exception to this are contributions that fall under the principle of fair use, which must be marked appropriately, and point to the copyright holder's copy of the material.

In general, uploading images to the wiki should be avoided if there is an existing Wikimedia Commons image that can be used instead. See Help:Images for more details.
