How I made AWS deployment work

[SarahJeanEwing]

The one click deployment didn't work for me, but here is what I uploaded in CloudFormation to make it work beautifully.

Go here: https://us-west-1.console.aws.amazon.com/cloudformation/home?region=us-east-1#/stacks/create

Change to "template" and change to "YAML" and paste the following (after pasting, click the "Create Stack" button)

Thank you Sarah! This is working!!

[mattiasJohnson]

Awesome thanks for the solution! Would be great if they could change the CloudFormation to this, would you mind making a pull request updating it?
