 :::
 
-### Below React Native 0.66
-
-You will need to add a polyfill for the Intl API on Android if:
-
-- You have [Hermes](https://github.com/facebook/hermes/issues/23) enabled and are below React Native 0.66.
-- You have [Hermes](https://github.com/facebook/hermes/issues/23) disabled and you want to support locales outside of en-US and you don't have the org.webkit:android-jsc-intl:+ variant enabled in your `app/build.gradle`.
-
-### Yarn Polyfills
-
-```bash
-yarn add react-native-localize @formatjs/intl-pluralrules @formatjs/intl-getcanonicallocales @formatjs/intl-listformat @formatjs/intl-displaynames @formatjs/intl-locale @formatjs/intl-datetimeformat @formatjs/intl-numberformat @formatjs/intl-relativetimeformat
-```
-
-### Npm Polyfills
-
-```bash
-npm install react-native-localize @formatjs/intl-pluralrules @formatjs/intl-getcanonicallocales @formatjs/intl-listformat @formatjs/intl-displaynames @formatjs/intl-locale @formatjs/intl-datetimeformat @formatjs/intl-numberformat @formatjs/intl-relativetimeformat --save
-```
-
-If using [Expo](https://docs.expo.dev/), omit `react-native-localize` and use `expo install expo-localization` instead. Read more [here](https://docs.expo.dev/versions/latest/sdk/localization/#installation).
-
-In your app starting entrypoint e.g. `./index.js` or even better use a `index.android.js` to prevent importing on iOS/web add the following code.
-
-:::info Note
-
-Don't forget to import the languages you want to support, in the example only english language is supported.
