+# Steps for creating VM templates with Hashicorp Packer
+
+As this is one of the early steps, the assumption is made that these commands will be run on a jumpbox/laptop.
+
+Templates will always live on <template-node> within the cluster.
+
+Steps to install Packer:
+
+```bash
+brew tap hashicorp/tap
+brew install hashicorp/tap/packer
+```
+
+packer plugins install github.com/hashicorp/proxmox
+packer plugins install github.com/hashicorp/ansible
