# Application layer for CHIP | |
## What is this? | |
The purpose of this folder is to contain functional ZCL Advanced Platform (CHIP) | |
plugins. A plugin is a discrete piece of Zigbee Cluster Library (ZCL) | |
functionality. Each plugin contains message processing code for a "Cluster" | |
within the Zigbee Cluster Library. Each plugin can be individually tested | |
through its own unit test code and Makefile. | |
## Usage | |
To build and run unit tests on these CHIP plugins run | |
| make test |
