= Introduction = Perform Dynamic DNS functions using AWS API Gateway and AWS Lambda. Currently, only Route53 and OVH are supported DNS providers.

= Development environment = Since the Lambda function is run on AWS Lambda, the packaging of this function requires Amazon Linux to prevent symbols errors in Python packages and external libraries.
