 ## Usage
 Use the provided 'build-dracut-initramfs.yml' playbook for the ansible provisioner in your packer template.
+You can use an already created qcow2 image, instead of always generating new packer images. See *run-playbook-only.json*
+for a sample packer template to use an existing qcow2 image and provision them with our playbook.
+The template requires the variable 'image_path' to be set, which needs to be the path of the qcow2 image.
+If it was generated by packer and the manifest was created, you can simply extract the image path from that:
+	packer build -var-file=base.json -only=qemu -var='image_path='"$(jq -r '.builds[0].files[0].name' < manifest.json)"'' test.json
