+## Custom Kubernetes version
+
 To build an image using a specific version of Kubernetes use the "PACKER_FLAGS" env var like in the example below:
 
 ```
 PACKER_FLAGS="--var 'kubernetes_rpm_version=1.28.3' --var 'kubernetes_semver=v1.28.3' --var 'kubernetes_series=v1.28' --var 'kubernetes_deb_version=1.28.3-1.1'" make build-proxmox-ubuntu-2204

-# ISO files
+## ISO files
 
 To use existing ISO files, set the `ISO_FILE` environment variable to the path of the ISO file.
 For example, to use a local ISO file, set the `ISO_FILE` environment variable like this:
 
 ```
 export ISO_FILE="local:iso/ubuntu-24.04.1-live-server-amd64.iso"
 ```

+## Flatcar for Proxmox
+
+Currently, Proxmox support is only available in the `alpha` channel of Flatcar.
+* https://www.flatcar.org/releases#alpha-release
+* https://github.com/coreos/fedora-coreos-tracker/issues/1652
+
+Therefore, we need to choose the right channel and version for flatcar along with `OEM_ID=proxmoxve`.
+
+**To build a Proxmox template for flatcar**
+
+```shell
+export PROXMOX_URL="https://example.net:8006/api2/json"
+export PROXMOX_USERNAME='root@pam!proxmox'
+export PROXMOX_TOKEN="xxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxxxxxx"
+export PROXMOX_NODE="pve1"
+export PROXMOX_ISO_POOL="local"
+export PROXMOX_BRIDGE="vmbr1"
+export PROXMOX_STORAGE_POOL="ceph_pool"
+
+## flatcar version
+export FLATCAR_VERSION=4152.0.0
+export FLATCAR_CHANNEL=alpha
+
+export OEM_ID=proxmoxve # make sure to choose OEM_ID=proxmoxve
+```
