 The AWS IoT Device Shadow library enables you to store and retrieve the current state (the “shadow”) of every registered device. The device’s shadow is a persistent, virtual representation of your device that you can interact with from AWS IoT Core even if the device is offline. The device state is captured as its “shadow” within a [JSON](https://www.json.org/) document. The device can send commands over MQTT to get, update and delete its latest state as well as receive notifications over MQTT about changes in its state. Each device’s shadow is uniquely identified by the name of the corresponding “thing”, a representation of a specific device or logical entity on the AWS Cloud. See [Managing Devices with AWS IoT](https://docs.aws.amazon.com/iot/latest/developerguide/iot-thing-management.html) for more information on IoT "thing". More details about AWS IoT Device Shadow can be found in [AWS IoT documentation](https://docs.aws.amazon.com/iot/latest/developerguide/iot-device-shadows.html). This library is distributed under the [MIT Open Source License](LICENSE). 
 
 **Note**: From [v1.1.0](https://github.com/aws/Device-Shadow-for-AWS-IoT-embedded-sdk/tree/v1.1.0) release onwards, you can used named shadow, a feature of the AWS IoT Device Shadow service that allows you to create multiple shadows for a single IoT device.
 
 This library has gone through code quality checks including verification that no function has a [GNU Complexity](https://www.gnu.org/software/complexity/manual/complexity.html) score over 8, and checks against deviations from mandatory rules in the [MISRA coding standard](https://www.misra.org.uk/MISRAHome/MISRAC2012/tabid/196/Default.aspx). Deviations from the MISRA C:2012 guidelines are documented under [MISRA Deviations](MISRA.md). This library has also undergone both static code analysis from [Coverity static analysis](https://scan.coverity.com/), and validation of memory safety and proof of functional correctness through the [CBMC automated reasoning tool](https://www.cprover.org/cbmc/).
