+Fenrir is a Linux screen reader. Linux is the only officially supported platform.
+
+**Other platforms (macOS, BSD, Windows):** Pull requests adding support for other operating systems may be accepted provided they do not break Linux functionality. However, no special care will be taken to preserve functionality on secondary platforms. If changes to Fenrir break support on a non-Linux OS, it is the responsibility of third-party contributors to submit fixes.
