+Terraform module that configures a multitude of [Opsgenie resources](https://registry.terraform.io/providers/opsgenie/opsgenie/latest/docs).

-This module is designed to accept an input configuration map. 
-One nice way of handling this is by passing resource definitions from a YAML configuration file.
