-# Description
-
-This is a dummy module which does not create any actual cloud resources. It's intended for registering hosts which cannot be managed with Terraform to our infra.
-
-For example providers like Hetzner or MacStadium have no provider module for Terrafom.
-
-This module creates the Ansible inventory hosts in order to make hosts appear the same way all the other hosts created by Terraform do.
