+从源码编译
+----------
+用户也可以从 PaddlePaddle 核心代码编译C++预测库，只需在编译时配制下面这些编译选项：
+
+=================   =========
+选项                 值   
+=================   =========
+CMAKE_BUILD_TYPE    Release
+FLUID_INSTALL_DIR   安装路径    
+WITH_FLUID_ONLY     ON（推荐）
+WITH_SWIG_PY        OFF（推荐
+WITH_PYTHON         OFF（推荐）
+WITH_GPU            ON/OFF
+WITH_MKL            ON/OFF
+=================   =========
+
+建议按照推荐值设置，以避免链接不必要的库。其它可选编译选项按需进行设定。
+
+下面的代码片段从github拉取最新代码，配制编译选项（需要将PADDLE_ROOT替换为PaddlePaddle预测库的安装路径）：
+
+  .. code-block:: bash
+
+     pip install paddlepaddle-gpu
+     PADDLE_ROOT=/path/of/capi
+     git clone https://github.com/PaddlePaddle/Paddle.git
+     cd Paddle
+     mkdir build
+     cd build
+     cmake -DFLUID_INSTALL_DIR=$PADDLE_ROOT \
+           -DCMAKE_BUILD_TYPE=Release \
+           -DWITH_FLUID_ONLY=ON \
+           -DWITH_SWIG_PY=OFF \
+           -DWITH_PYTHON=OFF \
+           -DWITH_MKL=OFF \
+           -DWITH_GPU=OFF  \
+           ..
+      make
+      make inference_lib_dist
+
+成功编译后，使用C++预测库所需的依赖（包括：（1）编译出的PaddlePaddle预测库和头文件；（2）第三方链接库和头文件；（3）版本信息与编译选项信息）
+均会存放于PADDLE_ROOT目录中。目录结构如下：
+
+  .. code-block:: text

+     │       └── zlib
+     └── version.txt
+     
+version.txt 中记录了该预测库的版本信息，包括Git Commit ID、使用OpenBlas或MKL数学库、CUDA/CUDNN版本号，如：
+
+  .. code-block:: text
+
+     GIT COMMIT ID: c95cd4742f02bb009e651a00b07b21c979637dc8
+     WITH_MKL: ON
+     WITH_GPU: ON
+     CUDA version: 8.0
+     CUDNN version: v5

-## 编译Fluid Inference库
-
-  - **不需要额外的CMake选项**
-    - 1、 配置CMake命令，更多配置请参考[源码编译PaddlePaddle](http://www.paddlepaddle.org/docs/develop/documentation/zh/build_and_install/build_from_source_cn.html)
-      ```bash
-      $ git clone https://github.com/PaddlePaddle/Paddle.git
-      $ cd Paddle
-      $ mkdir build
-      $ cd build
-      $ cmake -DCMAKE_INSTALL_PREFIX=your/path/to/paddle_inference_lib \
-          -DCMAKE_BUILD_TYPE=Release \
-          -DWITH_PYTHON=ON \
-          -DWITH_MKL=OFF \
-          -DWITH_GPU=OFF \
-          ..
-      ```
-
-    - 2、 编译PaddlePaddle
-      ```bash
-      $ make
-      ```
-
-    - 3、 部署。执行如下命令将PaddlePaddle Fluid Inference库部署到`your/path/to/paddle_inference_lib`目录。
-      ```bash
-      $ make inference_lib_dist
-      ```
-
-- 目录结构
-
-  ```bash
-  $ cd your/path/to/paddle_inference_lib
-  $ tree
-  .

-  |       |-- glog
-  |       `-- protobuf
-  `-- ...
-  ```
-
-  假设`PADDLE_ROOT=your/path/to/paddle_inference_lib`。
