+# Virtual Joystick Support for macOS
+
+Adds support for a virtual joystick output, based on the foohid driver for virtual HID devices.
+
+## Usage
+
+Install the latest [foohid HID driver](https://github.com/unbit/foohid/releases/).
+
+Select "Virtual Joystick" as the output in OpenTrack.
+
+The X, Y, Z, Yaw, Pitch, and Roll tracking axes are mapped to the joystick's X, Y, Z, RX, RY,
+and RZ axes respectively.
+
+# Building
+
+The implementation only uses standard libraries that are pre-installed on macOS. There are no
+special requirements for building.
