+## A word about Github
+
+== We're Using GitHub Under Protest ==
+
+This project is currently **mirrored** to GitHub. This is not ideal; GitHub is a
+proprietary, trade-secret system that is not Free and Open Souce Software
+(FOSS). We are deeply concerned about using a proprietary system like GitHub
+to develop our FOSS project. We have an
+[open Gitea repository ](https://gitea.ocram85.com/CodeServer/arkanum/issues) where the
+project contributors are actively discussing how we can move away from GitHub
+in the long term. We urge you to read about the
+[Give up GitHub](https://GiveUpGitHub.org) campaign from
+[the Software Freedom Conservancy](https://sfconservancy.org) to understand
+some of the reasons why GitHub is not a good place to host FOSS projects.
+
+If you are a contributor who personally has already quit using GitHub, please
+[check this resource](https://gitea.ocram85.com/CodeServer/arkanum) for how to send us contributions without
+using GitHub directly.
+
+Any use of this project's code by GitHub Copilot, past or present, is done
+without our permission.  We do not consent to GitHub's use of this project's
+code in Copilot.
