 Greengrass SDK
 =====================
 
-The AWS Greengrass Core SDK is meant to be used by AWS Lambda functions running on an AWS Greengrass Core. It will enable Lambda functions to invoke other Lambda functions deployed to the Greengrass Core, publish messages to the Greengrass Core and work with the local Shadow service.
-You can find the latest, most up to date, documentation at our `doc site <http://aws-greengrass-core-sdk-python-docs.s3-website-us-east-1.amazonaws.com/v1.3.0/index.html>`_.

-To use the AWS Greengrass Core SDK, you must first import the AWS Greengrass Core SDK in your Lambda function as you would with any other external libraries. You then need to create a client for 'iot-data' or 'lambda'. Use 'iot-data' if you wish to publish messages to the local AWS Greengrass Core and interact with the local Shadow service. Use 'lambda' if you wish to invoke other Lambda functions deployed to the same AWS Greengrass Core.
