-## Local User-Interface
-
-You can also utilize LocalStack's local CloudFormation user-interface to deploy and manage your CloudFormation stacks using public templates.
-You can access the user-interface at [`localhost:4566/_localstack/cloudformation/deploy`](http://localhost:4566/_localstack/cloudformation/deploy).

-
-You can utilize the CloudFormation user interface to provide an existing CloudFormation template URL, input the necessary parameters, and initiate the deployment directly from your browser.
-Let's proceed with an example template to deploy a CloudFormation stack.
-
-To begin, employ the public CloudFormation template URL: [`s3.eu-central-1.amazonaws.com/cloudformation-templates-eu-central-1/DynamoDB_Secondary_Indexes.template`](https://s3.eu-central-1.amazonaws.com/cloudformation-templates-eu-central-1/DynamoDB_Secondary_Indexes.template).
-
-Following this, download the template URL and extract the stack parameters (default values will be automatically applied).
-Upon submission, the stack deployment will be triggered, and a result message will be displayed.
-
 ## Resource Browser
 
 The LocalStack Web Application provides a Resource Browser for managing CloudFormation stacks to manage your AWS resources locally.
