+# debian packer template for Hetzner Cloud
+
+This repo is used to debian linux images (as snapshots) for use with
+[Hetzner Cloud](https://www.hetzner.de/cloud) by means of HashiCorp's
+[Packer](https://packer.io/).
+
+## Building Images using this Repo
+
+Please ensure that you have done the following:
+
+  - installed `packer` on your development machine
+  - set the `HCLOUD_TOKEN` environment variable to your API token
+  - reviewed/overriden the templates' variables (as necessary)
+
+### Internals
+
+The resulting images are intended to support a Terraform-based (or
+custom) workflow that feels close to the one of native Hetzner VMs.
+
+In particular, support for the following features available on
+standard Hetzner VMs is desired:
+
+  - dynamic hostname
+  - dynamic root ssh keys
+  - free-form cloud-init userdata
+  - full IPv6/IPv4 support
+  - Hetzner Cloud Networks
+  - Hetzner Cloud Volumes
