 To use Expo modules in your app, you will need to install and configure the `expo` package.
 
 The `expo` package has a small footprint; it includes only a minimal set of packages that are needed in nearly every app and the module and autolinking infrastructure that other Expo SDK packages are built with. Once the `expo` package is installed and configured in your project, you can use `npx expo install` to add any other Expo module from the SDK.

-There are [many advantages](/workflow/prebuild#pitch) of using [Expo Prebuild][prebuild] to generate your native projects. This guide will show you how to adopt Expo Prebuild in a project that was bootstrapped with `npx react-native init`. The amount of time it will take to convert your project depends on the amount of custom native changes that you have made to your iOS and Android native projects — on a brand new project, this may take a minute or two, and on a large project it could be much longer.

 > **warning** [Not all versions of `react-native` are explicitly supported][version-support]. Make sure to use a version of `react-native` that has a corresponding Expo SDK version.
 
 ## Install the `expo` package
 
 The `expo` package contains the [`npx expo prebuild`](/more/expo-cli/#prebuild) command and indicates which [prebuild template](/workflow/prebuild#templates) to use:
 
-<Terminal cmd={['$ yarn add expo']} />
+<Terminal cmd={['$ npm install expo']} />
 
 Ensure you install the version of `expo` that works for your currently installed version of `react-native`: [supported versions](version-support).
