-++++++++
+PaddlePaddle provides various methods of installation for many different users
 
-You can choose either pip or Docker to complete your install:
+Focus on Deep Learning Model Development

-   pip_install_en.rst
-   docker_install_en.rst
+	pip_install_en.rst
 
-Build from Source
------------------
+This is the most convenient way of installation. Please choose the right installation package with machine configure and system.

+Follow the Bottom Frame

+
+PaddlePaddle also supports installation using Docker. Please refer to the tutorial below:
+

+	:maxdepth: 1
+
+	docker_install_en.rst
 
-..  warning::
+We recommend running PaddlePaddle in Docker. This method has the following advantages：
 
-    We recommend to directly install via above installation steps, you'll only need to build PaddlePaddle from source when you need a modifed binary.
+- Does not require installation of third-party dependencies. 
+- Easy to share runtime environment. 
 
-..  toctree::
+Lastly, users can also compile and install PaddlePaddle from source code. The instructions are below:
+
+.. toctree::
     :maxdepth: 1
 
-    build_from_source_en.md
+    build_from_source_en.rst
+
+.. warning::
+
+	One caveat with this approach is that developers will have to download, compile and install all third-party dependencies. Thus this process of installation is more time consuming.
