Merge pull request #951 from kuke/update_sh

Update training & profiling scripts for new config

fluid/DeepASR/README.md

 The minimum PaddlePaddle version needed for the code sample in this directory is the lastest develop branch. If you are on a version of PaddlePaddle earlier than this, [please update your installation](http://www.paddlepaddle.org/docs/develop/documentation/en/build_and_install/pip_install_en.html).

-### TODO
+## Deep Automatic Speech Recognition
 
-This project is still under active development.
+### Introduction
+TBD
+
+### Installation
+
+#### Kaldi
+The decoder depends on [kaldi](https://github.com/kaldi-asr/kaldi), install it by flowing its instructions. Then
+
+```shell
+export KALDI_ROOT=<absolute path to kaldi>
+```
+
+#### Decoder
+
+```shell
+git clone https://github.com/PaddlePaddle/models.git
+cd models/fluid/DeepASR/decoder
+sh setup.sh
+```
+
+### Data reprocessing
+TBD
+
+### Training
+TBD
+
+
+### Inference & Decoding
+TBD
+
+### Question and Contribution
+TBD
