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.
When using the PaddlePaddle.org to compile documentations, the compiled documentations will be stored under a consolidated directory: .ppo_workspace/content

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 # Create paddlepaddle working directory
    cd paddlepaddle

    # Clone the content repositories. You may only clone the contents you need
    git clone https://github.com/PaddlePaddle/Paddle.git
    git clone https://github.com/PaddlePaddle/book.git
    git clone https://github.com/PaddlePaddle/models.git
    git clone https://github.com/PaddlePaddle/Mobile.git

    # Please specify the working directory through -v
    docker run -it -p 8000:8000 -v `pwd`:/var/content docker.paddlepaddle.org/paddle:latest

Note: PaddlePaddle.org will read the content repos specified in the -v (volume) flag of the docker run command
Use a web browser and navigate to http://localhost:8000, click the buttons to compile the documentation
The compiled documentations will be stored in <paddlepaddle working directory>/.ppo_workspace/content


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 # Create paddlepaddle working directory
    cd paddlepaddle

    # Clone the content repositories and PaddlePaddle.org
    git clone https://github.com/PaddlePaddle/Paddle.git
    git clone https://github.com/PaddlePaddle/book.git
    git clone https://github.com/PaddlePaddle/models.git
    git clone https://github.com/PaddlePaddle/Mobile.git
    git clone https://github.com/PaddlePaddle/PaddlePaddle.org.git

    # Please specify the PaddlePaddle working directory. In the current setting, it should be pwd
    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
The compiled documentations will be stored in <paddlepaddle working directory>/.ppo_workspace/content

How to write Documentations
============

PaddlePaddle uses `sphinx`_ to compile documentations，Please check sphinx official website for more detail.
