Before proceeding to the next section, install the following prerequisites on your machine:

* install the [CloudFormation Command Line Interface (CLI)](https://docs.aws.amazon.com/cloudformation-cli/latest/userguide/what-is-cloudformation-cli.html).

  Use `pip` to install the CloudFormation CLI:

::alert[If you already have version 1.0 of the CloudFormation CLI installed, it is recommended to upgrade it to version 2.0. For the upgrade, you can use the `--upgrade` option for the `pip install` command shown previously. For more information, see *Upgrading to CFN-CLI 2.0* further down on this [page](https://docs.aws.amazon.com/cloudformation-cli/latest/userguide/what-is-cloudformation-cli.html#resource-type-setup).]{type="info"}
