+TODO: WIP
+
+### Proxmox Builder
+
+The [Proxmox](../infra/proxmox.md) Packer builder is able to create virtual machines and store them as new images using [proxmox-clone](https://developer.hashicorp.com/packer/plugins/builders/proxmox/clone), and [proxmox-iso](https://developer.hashicorp.com/packer/plugins/builders/proxmox/iso).
+
+#### Authentication
+
+TODO: WIP
+
+You can also use the [environment variables](../linux/environment-variables-in-linux.md) `PROXMOX_URL`, `PROXMOX_USERNAME`, `PROXMOX_PASSWORD`, and `PROXMOX_TOKEN` to authenticate to [Proxmox](infra/proxmox.md).
