+libkeyfinder is a small C++11 library for estimating the musical key of digital
+audio. It is published under the GNU General Public License version 3 or later.
+
+It was written by Ibrahim Shaath who wrote it in 2011 as part of a master's 
+thesis in computer science. A GUI application to use it is available for macOS 
+and Windows, however that is no longer maintained and does not build on 
+contemporary Linux distributions.
+
+In 2020, Ibrahim handed over maintenance of libkeyfinder to the Mixxx DJ 
+software team who incorporated it into Mixxx as of Mixxx 2.3. If you want to 
+discuss anything related to libkeyfinder with us, please get in touch on the 
+Mixxx Zulip chat. Contributions are welcome by opening pull requests and issues
+on GitHub.
