Github recipes are the "works on my machine!" of the new millennium. Just like pecking in programs from computer magazines in the 1980s, only better!

I like the ones that are hardcoded to a specific name in a home directory best. Especially when it doesn't match the github name of the "creator."

I've added a note that the AMI's region must be us-west-1. Thanks for the heads up!

An AMI id is region-specific, the original poster should probably have mentioned what region he created the AMI in.
