+## Acquision of Models
+At present Paddle-Mobile only supports Paddle fluid training model. Models wiil be operated regularly after transformation if you have various models.
+### 1. Use Paddle Fluid directly to train
+It is the most reliable method to be recommanded
+### 2. Transform Caffe to Paddle Fluid model
+[https://github.com/PaddlePaddle/models/tree/develop/fluid/image_classification/caffe2fluid](https://github.com/PaddlePaddle/models/tree/develop/fluid/image_classification/caffe2fluid)
+### 3. ONNX
+ONNX is expanded as Open Neural Network Exchange. The project is aimed to make a full communication and usage among diffrent nerual network development frameworks.
+
+Except for directly using fluid models trained by PaddlePaddle,you can also get certain Paddle fluid models through onnx transformation.
+
+At present，work in support of onnx is also under operation in Baidu. Related tranformation project can be referred to here：
