# shows how to use the Ruby AWS SDK to list EC2 instance IDs
# when your API credentials have been placed under MFA requirements

# Prerequisites:
# you are running on a host that already has the AWS CLI set up with an IAM key pair
# that can describe EC2 instances (OTHERWISE, just pass a
# secret_access_id / secret_access_key pair to the STS client initializer)

# You have installed the Ruby AWS SDK Gem
# http://aws.amazon.com/sdk-for-ruby/
