Bind React App Server to Different Port

Q: I have created a React App with create-react-app. How do I start up on a port other than 3000?
A: Update the start command in package.json?

{
   ...
  "scripts": {
    "start": "PORT=3010 react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test --env=jsdom",
    "eject": "react-scripts eject"
  }
}
