+  The toolbox directly supports popular and contemporary detection frameworks, *e.g.* Faster RCNN, Mask RCNN, RetinaNet, etc.
 
-- **Efficient**
+- **High efficiency**
 
   All basic bbox and mask operations run on GPUs now.
   The training speed is nearly 2x faster than Detectron and comparable to maskrcnn-benchmark.
 
 - **State of the art**
