+It's hard to solve a problem when important details are missing.
+Before submitting the issue, look over the following criteria before handing your request in.
+
+- [ ] Was there a similar issue submitted or resolved before ? You could search issue in the github.
+- [ ] Did you retrieve your issue from widespread search engines ?
+- [ ] Is my description of the issue clear enough to reproduce this problem?
+   * If some errors occurred, we need details about `how do you run your code?`, `what system do you use?`, `Are you using GPU or not?`, etc.
+   * If you use an recording [asciinema](https://asciinema.org/) to show what you are doing to make it happen, that's awesome! We could help you solve the problem more quickly.
+- [ ] Is my description of the issue use the github markdown correctly?

-A pre-release version is available now for those who are eager to take a look.
+Welcome to the PaddlePaddle GitHub.
 
 PaddlePaddle (PArallel Distributed Deep LEarning) is an easy-to-use,
 efficient, flexible and scalable deep learning platform, which is originally
 developed by Baidu scientists and engineers for the purpose of applying deep
 learning to many products at Baidu.
 
+Our vision is to enable deep learning for everyone via PaddlePaddle.
+Please refer to our [release announcement](https://github.com/baidu/Paddle/releases) to track the latest feature of PaddlePaddle. 
+
 ## Features
 
 - **Flexibility**
 
-   PaddlePaddle supports a wide range of neural network architectures and
-   optimization algorithms. It is easy to configure complex models such as
-   neural machine translation model with attention mechanism or complex memory
-   connection.

+    neural machine translation model with attention mechanism or complex memory
+    connection.
 
 -  **Efficiency**
 
-  In order to unleash the power of heterogeneous computing resource,
-  optimization occurs at different levels of PaddlePaddle, including
-  computing, memory, architecture and communication. The following are some
-  examples:
-  1. Optimized math operations through SSE/AVX intrinsics, BLAS libraries
-  (e.g. MKL, ATLAS, cuBLAS) or customized CPU/GPU kernels. 
-  2. Highly optimized recurrent networks which can handle **variable-length** 
-  sequence without padding.
-  3. Optimized local and distributed training for models with high dimensional
-  sparse data.

 - **Scalability**
 
-  With PaddlePaddle, it is easy to use many CPUs/GPUs and machines to speed
-  up your training. PaddlePaddle can achieve high throughput and performance
-  via optimized communication.

 - **Connected to Products**
 
-  In addition, PaddlePaddle is also designed to be easily deployable. At Baidu,
-  PaddlePaddle has been deployed into products or service with a vast number
-  of users, including ad click-through rate (CTR) prediction, large-scale image
-  classification, optical character recognition(OCR), search ranking, computer
-  virus detection, recommendation, etc. It is widely utilized in products at
-  Baidu and it has achieved a significant impact. We hope you can also exploit
-  the capability of PaddlePaddle to make a huge impact for your product.
