+# Model Zoo
+
+This page lists model archives that are pre-trained and pre-packaged, ready to be served for inference with PaddleServing. 
+ To propose a model for inclusion, please submit [pull request](https://github.com/PaddlePaddle/Serving/pulls)
+
+Special thanks to the [Padddle wholechain](https://www.paddlepaddle.org.cn/wholechain) and [PaddleHub](https://www.paddlepaddle.org.cn/hub) whose Model Zoo and Model Examples were used in generating these model archives
