PaddlePaddle supports English documentation ``doc`` and Chinese documentation ``doc_cn``.
Both are compiled by `cmake`_ and `sphinx`_ , the compiled documentations will be stored under ``doc`` and ``doc_cn`` directories.

How to Build Documentations
============

We recommend using PaddlePaddle.org tool to build documentation


Use PaddlePaddle.org tool
--------------
This is the recommended method to build documentation. It can compile documentation and preview the documentation in a web browser.

The tool uses Docker, please install it on your system. Please check Docker official website on how to install Docker. You may use the following commands to activate the tool

..  code-block:: bash

    mkdir paddlepaddle
    cd paddlepaddle
    git clone git@github.com:PaddlePaddle/Paddle.git
    git clone git@github.com:PaddlePaddle/book.git
    git clone git@github.com:PaddlePaddle/models.git

    docker run -it -p 8000:8000 paddlepaddle/paddlepaddle.org:latest

Use a web browser and navigate to http://localhost:8000, click the buttons to compile the documentation

If you don't wish to use Docker, you can also activate the tool through Django. Use the following the commands to set up

..  code-block:: bash

    mkdir paddlepaddle
    cd paddlepaddle
    git clone git@github.com:PaddlePaddle/Paddle.git
    git clone git@github.com:PaddlePaddle/book.git
    git clone git@github.com:PaddlePaddle/models.git
    git clone git@github.com:PaddlePaddle/PaddlePaddle.org.git
    export CONTENT_DIR=<path_to_paddlepaddle_working_directory>
    export ENV=''
    cd PaddlePaddle.org/portal/
    pip install -r requirements.txt
    python manage.py runserver

Use a web browser and navigate to http://localhost:8000, click the buttons to compile the documentation
