 The key features of OpenCDA are:
-* <strong>Full-stack CDA System</strong>: OpenCDA provides a full-stack automated driving and cooperative driving software system that contains perception, localization, planning, control, and V2X communication modules. 
-* <strong>Connectivity and Cooperation</strong>: OpenCDA supports various levels and categories of cooperation between CAVs in simulation.
-  This differentiates OpenCDA with other single vehicle automation tools.
-* <strong>Integration</strong>: OpenCDA utilizes CARLA and SUMO separately, as well as integrates them together for realistic scene rendering, vehicle modeling, and traffic simulation. It is also efficient and flexible enough to be applied for software-in-the-loop and hardware-in-the-loop testing.

+* <strong> Full-stack</strong> prototype CDA Platform in Simulation: OpenCDA provides a simple prototype automated driving and cooperative driving platform, all in Python, that contains perception, localization, planning, control, and V2X communication modules.
 * <strong>Modularity</strong>: OpenCDA is highly modularized, enabling users to conveniently replace any default algorithms or protocols with their own customzied design. 
 * <strong>Benchmark</strong>: OpenCDA offers benchmark testing scenarios, benchmark baseline maps, state-of-the-art benchmark algorithms for ADS and Cooperative ADS functions, and benchmark evaluation metrics.
