-# CarSim Integration (Beta)
+# CarSim Integration
 
 CARLA's integration with CarSim allows vehicle controls in CARLA to be forwarded to CarSim. CarSim will do all required physics calculations of the vehicle and return the new state to CARLA. 
 
 This page shows you how to generate a `.sim` file, explains how vehicle dimensions relate between CARLA and CarSim and how to run a simulation on CARLA using the CarSim integration.
