to deploy a stack that creates the Lambda functions for you. Remember the stack name.
2. Include the following resources in your CloudFormation template. These will create a) a nested stack that
looks up the ARNs from the previous step and b) a custom resource that allows your template to read those ARNs.

## A note on AWS Regions
At times, AWS can be touchy when it comes to referencing resources across regions. With that in mind, this
project is replicated to all regions - so you simply need to reference the version that lives in the S3
bucket that corresponds to the region you're working in. If there is a new region that is not part of the
ring of replications, please create an [issue](https://github.com/gilt/cloudformation-helpers/issues).

Unfortunately we can't use the Github .zip file directly, because it zips the code into a subdirectory named after
the repo; AWS Lambda then can't find the .js file containing the helper functions because it is not on the top-level.
