 The command will exit when the stack creation is successful. If you'd like to watch it create in real-time, you can log into the cloudformation console.
 
 To get the URL for the newly created developer portal instance, find the websiteURL field in the cloudformation console's outputs or run this command:
 
 ```bash
-aws cloudformation describe-stacks --query "Stacks[?StackName=='dev-portal'][Outputs[?OutputKey=='WebsiteURL']][][].OutputValue"
+aws cloudformation describe-stacks --query \
+    "Stacks[?StackName=='dev-portal'][Outputs[?OutputKey=='WebsiteURL']][][].OutputValue"
 ```
 
 You can override any of the parameters in the template using the `--parameter-overrides key="value"` format. This will be necessary if you intend to deploy several instances of the developer portal or customize some of the features. You can see a full list of overridable parameters in `cloudformation/template.yaml` under the `Parameters` section.
