-This section will talk about how to implement a CustomDevice plug-in and add a new device backend for PaddlePaddle. How to compile, package, install, and use the backend will also be introduced.
+In this section we will walk through the steps required to extend a fake hardware backend for PaddlePaddle by implementing a fake device named CustomCPU.
 
 > Note：
 > - Please make sure that you have correctly installed the latest version of [Paddle develop](https://github.com/PaddlePaddle/Paddle).
 > - Only `Linux` is supported
-> - PaddlePaddle can have the custom kernel code and registration of open functional statements in heder files.

-The custom device access decouples the framework from the device and makes it available to extend the backend of the PaddlePaddle device via plug-ins. In this way, developers can make a plug-in for PaddlePaddle only by implementing the standard API and compiling it into a dynamic-link library, instead of by modifying the code of PaddlePaddle. Now it is easier to develop hardware backends for PaddlePaddle.
