 * Inventory files are under `inv/`. For AWS `cfn-init` the inventory
   `inv/aws_node_local` inventory is probably what you want.
     * Note that this expects the environment to be setup with infrastructure information (refer to the _Usage_ section above).
 * Global group vars loaded automatically from `group_vars/<group>.yml`. In
   particular note `group_vars/aws_node_local.yml` which loads infrastructure
   information from the environment.
