Sending a SMS via Amazon's SNS

I’m currently using peerlibrary:aws-sdk to interface with a few Amazon services. I’m now looking to send SMS messages to phone numbers using this same SDK wrapper.

What I’m trying to figure out are the steps involved. This is the link to the SDK, but I have yet to find a comprehensive guide.

Has anyone sent messages via SNS and peerlibrary:aws-sdk’s SDK wrapper?

This is my SO question on this topic.
