 import paddle_serving_client.io as serving_io
 serving_io.inference_model_to_serving(dirname, serving_server="serving_server", serving_client="serving_client", model_filename=None, params_filename=None )
 ```
-dirname (str) - Path of saved model files. Program file and parameter files are saved in this directory.
-
-serving_server (str, optional) - The path of model files and configuration files for server. Default: "serving_server".
-
-serving_client (str, optional) - The path of configuration files for client. Default: "serving_client".
-
-model_filename (str, optional) - The name of file to load the inference program. If it is None, the default filename `__model__` will be used. Default: None.
-
-paras_filename (str, optional) - The name of file to load all parameters. It is only used for the case that all parameters were saved in a single binary file. If parameters were saved in separate files, set it as None. Default: None.
+Or you can use a build-in python module called `paddle_serving_client.convert` to convert it.
+```python
+python -m paddle_serving_client.convert --dirname ./your_inference_model_dir
+```
+Arguments are the same as `inference_model_to_serving` API.
+| Argument | Type | Default | Description |
+|--------------|------|-----------|--------------------------------|
+| `dirname` | str | - | Path of saved model files. Program file and parameter files are saved in this directory. |
+| `serving_server` | str | `"serving_server"` | The path of model files and configuration files for server. |
+| `serving_client` | str | `"serving_client"` | The path of configuration files for client. |
+| `model_filename` | str | None | The name of file to load the inference program. If it is None, the default filename `__model__` will be used. |
