 如何贡献/修改文档
 ##################
 
-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。
+PaddlePaddle的文档文件都在 :code:`doc` 这个子目录里。源文件是 `RST <http://docutils.sourceforge.net/docs/user/rst/quickref.html>`_ 格式的。 在编译PaddlePaddle源码的时候，可以选择让 `cmake<https://cmake.org/>`_ 调用 `sphinx <http://www.sphinx-doc.org/en/1.4.8/>`_ 从 RST 文件生成 HTML 格式的文档。
 
 
 如何构建PaddlePaddle的文档
 ==========================
 
-PaddlePaddle的文档构建有直接构建和基于Docker构建两种方式，我们提供了一个构建脚本build_docs.sh来进行构建。
-PaddlePaddle文档需要准备的环境相对较复杂，所以我们推荐使用基于Docker来构建PaddlePaddle的文档。
+为了简化大家安装文档构建工具的过程，我们提供一个Docker image。

+Build Documents
+###############
+
+Document files of PaddlePaddle are in sub-directory :code:`doc`.  Source files are in `RST <http://docutils.sourceforge.net/docs/user/rst/quickref.html>`_ format.  We can build the document by letting `cmake<https://cmake.org/>`_ invoke `sphinx <http://www.sphinx-doc.org/en/1.4.8/>`_  to convert RST files into HTML files.
+
+
+How to Build Documents
+======================
+
+To save the time of installing building tools, we provide a Docker image.
+
+
+使用Docker构建PaddlePaddle的文档
+--------------------------------
+
+使用Docker构建PaddlePaddle的文档，需要在系统里先安装好Docker工具包。Docker安装请参考 `Docker的官网 <https://docs.docker.com/>`_ 。安装好Docker之后可以使用源码目录下的脚本构建文档，即
+
+..  code-block:: bash
+
+    cd TO_YOUR_PADDLE_CLONE_PATH
+    cd paddle/scripts/tools/build_docs
+    bash build_docs.sh with_docker
+
+编译完成后，会在当前目录生成两个子目录\:
+
+* doc 英文文档目录
+* doc_cn 中文文档目录
+
+打开浏览器访问对应目录下的index.html即可访问本地文档。
+
+
+
+直接构建PaddlePaddle的文档
+--------------------------
+
+因为PaddlePaddle的v2 api文档生成过程依赖于py_paddle Python包，用户需要首先确认py_paddle包已经安装。
+
+..  code-block:: bash
+
+    python -c "import py_paddle"
+
+如果提示错误，那么用户需要在本地编译安装PaddlePaddle，请参考 `源码编译文档 <http://www.paddlepaddle.org/develop/doc/getstarted/build_and_install/build_from_source_en.html>`_ 。
+注意，用户在首次编译安装PaddlePaddle时，请将WITH_DOC选项关闭。在编译安装正确之后，请再次确认py_paddle包已经安装，即可进行下一步操作。
+
+如果提示正确，可以执行以下命令编译生成文档，即
+
+..  code-block:: bash
+
+    cd TO_YOUR_PADDLE_CLONE_PATH
+    cd paddle/scripts/tools/build_docs
+    bash build_docs.sh local
+
+编译完成之后，会在当前目录生成两个子目录\:
+
+* doc 英文文档目录
+* doc_cn 中文文档目录
+
+打开浏览器访问对应目录下的index.html即可访问本地文档。
+
+
+如何书写PaddlePaddle的文档
+==========================
+
+PaddlePaddle文档使用 `sphinx`_ 自动生成，用户可以参考sphinx教程进行书写。
+
+如何更新www.paddlepaddle.org文档
+================================
+
+开发者给PaddlePaddle代码增加的注释以PR的形式提交到github中，提交方式可参见 `贡献文档 <http://paddlepaddle.org/develop/doc_cn/howto/dev/contribute_to_paddle_cn.html>`_ 。
+目前PaddlePaddle的develop分支的文档是自动触发更新的，用户可以分别查看最新的 `中文文档 <http://www.paddlepaddle.org/develop/doc_cn/>`_ 和
+`英文文档 <http://www.paddlepaddle.org/develop/doc/>`_ 。
