 ## :question: FAQ
 
-### What's included in this template?
+### Why this template when React Native 0.57+ supports TypeScript out of the box?
+
+First of all, I started this template before React Native 0.57 came out. After React Native 0.57 was announced, I planned to stop maintenance on this template. But after further evaluation, there's still some 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)
-- [React Native TypeScript Transformer](https://github.com/ds300/react-native-typescript-transformer)
 - [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.

 It deletes obsolete files like the `.flowconfig` and the `setup.js` itself after the setup.
 
+### How to do type checking?
+
+`npm run tsc`
+
 ### Does debugging work?
 
 Yes it does.
