The command "surge teardown ${my_custom_domain}" is used to destroy or remove a project from the Surge service with a custom domain.

• "surge" is a command-line tool for quickly deploying static websites to the internet, provided by the surge.sh service.
• "teardown" is one of the surge commands, which means to tear down or remove a project from Surge's servers.
• "${my_custom_domain-com}" is a placeholder for the custom domain that you have associated with your project. It should be replaced with the actual domain name, without the "http://" or "https://" prefix.

So, the command "surge teardown ${my_custom_domain-com}" is instructing the Surge tool to remove the project associated with the specified custom domain from the Surge service.
