+robotpy-halsim-ds-socket
+==================
+
+Installing this package will allow you to utilize the 2020+ WPILib GUI
+DS Socket from a RobotPy program.
+
+Usage
+-----
+
+First, install pyfrc. Then run your robot with the 'sim' argument and --ds-socket flag:
+
+    # Windows
+    py -3 -m robotpy sim --ds-socket
+
+    # Linux/OSX
+    python3 -m robotpy sim --ds-socket
+
+WPILib's documentation for using the simulator can be found at http://docs.wpilib.org/en/latest/docs/software/wpilib-tools/robot-simulation/
