+### Provider usage
+You can start from either an ISO or clone an existing VM.
+
+Optimally, you could create a VM resource you will use a clone base with an ISO, and make the rest of the VM resources depend on that base "template" and clone it.
+
+Interesting parameters:
+
+**ssh_forward_ip** - should be the IP or hostname of the target node or bridge IP. This is where proxmox will create a port forward to your VM with via a user_net.
+
+**os_type** - ubuntu (https://github.com/Telmate/terraform-ubuntu-proxmox-iso) or centos (TODO: centos iso template)
 
 
+### Preprovision (internal)
+
+There is a pre-provision phase which is used to set a hostname, intialize eth0, and resize the VM disk to available space. This is done over SSH with the ssh_forward_ip, ssh_user and ssh_private_key.
+
+Disk resize is done if the file /etc/auto_resize_vda.sh exists. Source: https://github.com/Telmate/terraform-ubuntu-proxmox-iso/blob/master/auto_resize_vda.sh
+
+### Provisioner usage
+
+
+Remove the temporary net1 adapter.
+Inside the VM this usually triggers the routes back to the provisioning machine on net0.
+```
+	provisioner "proxmox" {
+		action = "sshbackward"
+	}
+
+```
+
+Replace the temporary net1 adapter with a new persistent net1.
+```
+	provisioner "proxmox" {
+		action = "reconnect"
+		net1 = "virtio,bridge=vmbr0,tag=99"
+	}
+
+```
+If net1 needs a config other than DHCP you should prior to this use provisioner "remote-exec" to modify the network config.
