 ## Constructing a Template for Packer
 
 Now that Packer is installed, you can make a Packer [template](https://www.packer.io/docs/templates). A template is a file that contains the configurations needed to build a machine image. A template can be formatted in [JSON](https://www.packer.io/docs/templates/legacy_json_templates) or [HCL2](https://www.packer.io/docs/templates/hcl_templates) (Hashicorp Configuration Language). As of Packer v1.7.0, the HCL2 template format is preferred and, as such, will be used in the examples within this guide.
