 PaddlePaddle的文档包括英文文档 ``doc`` 和中文文档 ``doc_cn`` 两个部分。文档都是通过 `cmake`_ 驱动 `sphinx`_ 编译生成，生成后的文档分别存储在编译目录的 ``doc`` 和 ``doc_cn`` 两个子目录下。

+也可以利用PaddlePaddle 工具来编译文档，这个情况下所有的文件会存在整理过的的文件目录 .ppo_workspace/content 下
 
 如何构建文档
 ============
 
-PaddlePaddle的文档构建有两种方式。
+PaddlePaddle的文档构建有三种方式。
+
+
+使用PaddlePaddle.org工具
+--------------
+这个是目前推荐的使用方法。除了可以自动编译文档，也可以直接在网页预览文档。
+
+文件工具是使用Docker，需要在系统里先安装好Docker工具包。Docker安装请参考Docker的官网。安装好Docker之后及可用以下命令启动工具
+
+..  code-block:: bash
+
+    mkdir paddlepaddle # Create paddlepaddle working directory
+    cd paddlepaddle
+
+    # Clone the content repositories
+    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 paddlepaddle/paddlepaddle.org:latest
+
+注意: PaddlePaddle.org 会在 -v (volume) 指定的内容存储库运行命令
+之后再用网页连到http://localhost:8000就可以在网页上生成需要的文档
+编译后的文件将被存储在工作目录 <paddlepaddle working directory>/.ppo_workspace/content。
+
+如果不想使用 Docker，你还可以通过运行Django框架直接激活工具的服务器。使用下面的命令来运行它。
+
+..  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
+
+工具服务器将读取环境变量 CONTENT_DIR 搜索代码库。请指定的PaddlePaddle工作目录给环境变量 CONTENT_DIR。
+之后再用网页连到http://localhost:8000就可以在网页上生成需要的文档。
+编译后的文件将被存储在工作目录 <paddlepaddle working directory>/.ppo_workspace/content。

+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 paddlepaddle/paddlepaddle.org: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
+
+If you want to learn more on the PaddlePaddle.org, please `click here <https://github.com/PaddlePaddle/PaddlePaddle.org/blob/develop/README.md>`_ 。
+
+How to write Documentations
+============
+
+PaddlePaddle uses `sphinx`_ to compile documentations，Please check sphinx official website for more detail.
+
+
+How to update www.paddlepaddle.org
+============================
+
+Please create PRs and submit them to github, please check `Contribute Code <http://www.paddlepaddle.org/docs/develop/documentation/en/howto/dev/contribute_to_paddle_en.html>`_ 。
+PaddlePaddle develop branch will update the documentation once the PR is merged. User may check latest `Chinese Docs <http://www.paddlepaddle.org/docs/develop/documentation/zh/getstarted/index_cn.html>`_ and
+`English Docs <http://www.paddlepaddle.org/docs/develop/documentation/en/getstarted/index_en.html>`_ 。
