-This script deploys applications with the [AWS Code Deploy](http://docs.aws.amazon.com/codedeploy/latest/userguide/welcome.html) service. This script has been adapted to be easily portable and configurable via environment variables such that it can be incorporated within CI services that do not natively include support for Code Deploy. Additionally, this script includes additional functionality described below that is typically not included in out-of-box Code Deploy CI systems. For more information, refer to the [AWS Code Deploy](http://docs.aws.amazon.com/codedeploy/latest/userguide/welcome.html) documentation or
-the [AWS CLI API](http://docs.aws.amazon.com/cli/latest/reference/deploy/index.html).
+This script deploys applications with the [AWS Code Deploy](http://docs.aws.amazon.com/codedeploy/latest/userguide/welcome.html) service. The script uses the AWS CLI for underlying commands and extends functionality to provide common requirements for applications being deployed including compression, encryption, bucket revision limiting, monitoring, and more. It also handles creation of defined AWS Code Deploy components as necessary (e.g. Deployment Groups). By utilizing environment variables, this script is easily portable and intended to run inside CI containers. For more information, refer to the [AWS Code Deploy](http://docs.aws.amazon.com/codedeploy/latest/userguide/welcome.html) documentation or the [AWS CLI API](http://docs.aws.amazon.com/cli/latest/reference/deploy/index.html).
 
 ### Features:
