**To describe a stack's layers**

The following ``describe-layers`` commmand describes the layers in a specified stack::

  aws opsworks --region us-east-1 describe-layers --stack-id 38ee91e2-abdc-4208-a107-0b7168b3cc7a

**Note**: AWS OpsWorks CLI commands should set the region to ``us-east-1`` regardless of the stack's location.
