 > Notes: 1.Here place an icon/image as the logo at the beginning like PaddleOCR or PaddleNLP; 2. Is there any idea to add [Parakeet logo](https://github.com/PaddlePaddle/Parakeet/blob/develop/docs/images/logo.png) into this .md document? 3. **It is strongly recommended to refer to [PaddleHub](https://github.com/PaddlePaddle/PaddleHub) documents.**
