First we need to install react-native-cli:
yarn global add react-native-cli
Next initialize your application.
react-native init <tmp_appname>
Rename the app and setup better bundle identifiers.
yarn add --dev react-native-rename
react-native-rename -b <bundle identifier> <app_name>
mkdir src
mv App.js src
Add Firebase, Redux, and device-info to the App.
yarn add react-native-firebase react-redux redux-form redux-thunk react-native-device-info
react-native link react-native-firebase react-native-device-info
