 ### Statement
 This module is migrated to [X2Paddle](https://github.com/PaddlePaddle/X2Paddle)
-
-### Key Features
-1. Convert caffe model to fluid model with codes of defining a network(useful for re-training)
-
-2. Pycaffe is not necessary when just want convert model without do caffe-inference
-
-3. Caffe's customized layers convertion also be supported by extending this tool
-
-4. A bunch of tools in `examples/imagenet/tools` are provided to compare the difference
-
-### HowTo
-1. Prepare `caffepb.py` in `./proto` if your python has no `pycaffe` module, two options provided here:
-    - Generate pycaffe from caffe.proto
-        ```
-        bash ./proto/compile.sh
-        ```
-
-    - Download one from github directly
-        ```
-        cd proto/ && wget https://raw.githubusercontent.com/ethereon/caffe-tensorflow/master/kaffe/caffe/caffepb.py
-        ```
-
-2. Convert the Caffe model to Fluid model
-   - Generate fluid code and weight file
-       ```
-       python convert.py alexnet.prototxt \
-               --caffemodel alexnet.caffemodel \
-               --data-output-path alexnet.npy \
-               --code-output-path alexnet.py
-       ```
-
-   - Save weights as fluid model file
-       ```
-       # only infer the last layer's result
-       python alexnet.py alexnet.npy ./fluid
-       # infer these 2 layer's result
-       python alexnet.py alexnet.npy ./fluid fc8,prob
-       ```
-
-3. Use the converted model to infer
-    - See more details in `examples/imagenet/tools/run.sh`
-
-4. Compare the inference results with caffe
-    - See more details in `examples/imagenet/tools/diff.sh`
-
-### How to convert custom layer
-1. Implement your custom layer in a file under `kaffe/custom_layers`, eg: mylayer.py
-    - Implement ```shape_func(input_shape, [other_caffe_params])``` to calculate the output shape
-    - Implement ```layer_func(inputs, name, [other_caffe_params])``` to construct a fluid layer
-    - Register these two functions ```register(kind='MyType', shape=shape_func, layer=layer_func)```
-    - Notes: more examples can be found in `kaffe/custom_layers`
-
-2. Add ```import mylayer``` to  `kaffe/custom_layers/\_\_init__.py`
-
-3. Prepare your pycaffe as your customized version(same as previous env prepare)
-    - (option1) replace `proto/caffe.proto` with your own caffe.proto and compile it
-    - (option2) change your `pycaffe` to the customized version
-
-4. Convert the Caffe model to Fluid model
-
-5. Set env $CAFFE2FLUID_CUSTOM_LAYERS to the parent directory of 'custom_layers'
-   ```
-   export CAFFE2FLUID_CUSTOM_LAYERS=/path/to/caffe2fluid/kaffe
-   ```
-
-6. Use the converted model when loading model in `xxxnet.py` and `xxxnet.npy`(no need if model is already in `fluid/model` and `fluid/params`)
