 It is not just an open-source hardware, but is an end to end solution that includes
 the entire software stack on top of VTA open-source hardware.
 
-
 The key features include:
 
 - Generic, modular open-source hardware
   - Streamlined workflow to deploy to FPGAs.
-  - Simulator support
-- Driver and JIT runtime for both simulated backend and FPGA.
+  - Simulator support to protoype compilation passes on regular workstations.
+- Driver and JIT runtime for both simulated and FPGA hardware backend.
 - End to end TVM stack integration
   - Direct optimization and deploy models from deep learning frameworks via TVM stack.
-  - Customized and extendible TVM compiler backend
-  - Flexible RPC support to ease the deployment, you can program it with python :)
