 You can replace `<EPHEMERAL_INSTANCE_ENDPOINT_URL>` with the endpoint URL of the Ephemeral Instance and `<BUCKET_NAME>` with the name of the S3 bucket you want to create. To query the list of S3 buckets in the Ephemeral Instance, run the following command:
 
 {{< command >}}
-$ aws --endpoint-url=<EPHEMERAL_INSTANCE_ENDPOINT_URL> s3 ls
+$ aws --endpoint-url='<EPHEMERAL_INSTANCE_ENDPOINT_URL>' s3 ls
 {{< /command >}}
 
 You can further use integrations, such as [CDK](https://docs.localstack.cloud/user-guide/integrations/aws-cdk/), [SAM CLI](https://docs.localstack.cloud/user-guide/integrations/aws-sam/), and [Terraform](https://docs.localstack.cloud/user-guide/integrations/terraform/), to interact with the Ephemeral Instance. In these integrations, you can change the `LOCALSTACK_HOSTNAME` environment variable to the endpoint URL of the Ephemeral Instance.
