<a name="using-aws-command-line-interface"></a>

 Determine whether the AWS Command Line Interface (AWS CLI) is available in your environment. For installation instructions, see [What Is the AWS Command Line Interface](https://docs.aws.amazon.com/cli/latest/userguide/cli-chap-welcome.html) in the *AWS CLI User Guide*. After confirming that the AWS CLI is available, run the following command. 

```
      $ aws cloudformation delete-stack --stack-name
      <installation-stack-name>
```

 Replace *<installation-stack-name**>* with the name of your CloudFormation stack.
