 ## :question: FAQ
 
-### Why this template when React Native 0.57+ supports TypeScript out of the box?
-
-Actually, when React Native 0.57 was announced, I planned to stop maintenance on this template. But after further evaluation, there's still quite a lot of manual work to do (add type definitions for React & React Native, create a `.tsconfig` for type checking, etc.) to properly set up a React Native 0.57+ TypeScript project. And that's where this template comes in and does that work for you. :raised_hands:
-
 ### What additional dependencies are included in this template?
 
 - [TypeScript](https://github.com/Microsoft/TypeScript)
 - [Type definitions for React & React Native](https://github.com/DefinitelyTyped/DefinitelyTyped)
-- [ts-jest](https://github.com/kulshekhar/ts-jest)
 
 This template always uses the latest versions of the dependencies at the time when the `react-native init` command is being executed. This means you don't have to worry about old versions.
 
 Lots of :heart: and credits to the owners and maintainers of those packages.
 
-### Why the setup script?
+### Does debugging work?
 
-It deletes obsolete files like the `.flowconfig` and the `setup.js` itself after the setup.
+Yes it does. :tada:
