# React Native experiments installation - Docs

1.  1

    ## Install the package

    Required

    Install the PostHog React Native library and its dependencies:

    PostHog AI

    ### Expo

    ```bash
    npx expo install posthog-react-native expo-file-system expo-application expo-device expo-localization
    ```

    ### yarn

    ```bash
    yarn add posthog-react-native @react-native-async-storage/async-storage react-native-device-info react-native-localize
    # for iOS
    cd ios && pod install
    ```

    ### npm

    ```bash
    npm i -s posthog-react-native @react-native-async-storage/async-storage react-native-device-info react-native-localize
    # for iOS
    cd ios && pod install
    ```

    ## Configure PostHog

    Required

    PostHog is most easily used via the `PostHogProvider` component. Wrap your app with the provider:

    App.tsx

    PostHog AI

    ```jsx
    import { PostHogProvider } from 'posthog-react-native'
    export function MyApp() {
        return (
            <PostHogProvider
                apiKey="<ph_project_token>"
                options={{
                    host: "https://us.i.posthog.com",
                }}
            >
                <RestOfApp />
            </PostHogProvider>
        )
    }
    ```

    ## Implement your experiment

    Required

    Experiments run on top of our feature flags. You can define which version of your code runs based on the return value of the feature flag:

    ```javascript
    if (posthog.getFeatureFlag('your-experiment-feature-flag') === 'test') {
        // Do something differently for this user
    } else {
        // It's a good idea to let control variant always be the default behaviour,
        // so if something goes wrong with flag evaluation, you don't break your app.
    }
    ```

    ## Run your experiment

    Required

    Once you've implemented the feature flag in your code, you'll enable it for a target audience by creating a new experiment in the PostHog dashboard.
