    You can follow the quick start tutorial to learn how use PaddlePaddle
    step-by-step.
     
-- [Example and Demo]() <br>
+- [Example and Demo](http://paddlepaddle.org/doc/demo/) <br>
    We provide five demos, including: image classification, sentiment analysis,
    sequence to sequence model, recommendation, semantic role labelling.

   This system supports training deep learning models on multiple machines
   with data parallelism.
    
-- [Python API]() <br>
+- [Python API](http://paddlepaddle.org/doc/ui/) <br>
    PaddlePaddle supports using either Python interface or C++ to build your
    system. We also use SWIG to wrap C++ source code to create a user friendly
    interface for Python. You can also use SWIG to create interface for your
    favorite programming language.
