+安装与编译
+==========
+
+.. _install_steps:
+
+PaddlePaddle针对不同的用户群体提供了多种安装方式。
+
+专注深度学习模型开发
+-----------------
+
+PaddlePaddle提供了多种python wheel包，可通过pip一键安装：
+
+.. toctree::
+	:maxdepth: 1
+
+	pip_install_cn.rst
+
+这是最便捷的安装方式，请根据机器配置和系统选择对应的安装包。
+
+关注底层框架
+----------
+
+PaddlePaddle提供了基于Docker的安装方式，请参照以下教程：
+
+.. toctree::
+	:maxdepth: 1
+
+	docker_install_cn.rst
+
+我们推荐在Docker中运行PaddlePaddle，该方式具有以下优势：
+
+- 无需单独安装第三方依赖
+- 方便分享运行时环境，易于问题的复现
+
+对于有定制化二进制文件需求的用户，我们同样提供了从源码编译安装PaddlePaddle的方法：
+
+.. toctree::
+    :maxdepth: 1
+
+    build_from_source_cn.rst
+
+.. warning::
+
+	需要提醒的是，这种安装方式会涉及到一些第三方库的下载、编译及安装，整个安装过程耗时较长。
