-[CodePush](https://microsoft.github.io/code-push) is a cloud service that enables React Native developers to deploy mobile app updates directly to their users' devices. It works by acting as a central repository that developers can publish updates to (JS, HTML, CSS and images), and that apps can query for updates from (using provided client SDK for [React Native](https://github.com/Microsoft/react-native-code-push)). This allows you to have a more deterministic and direct engagement model with your userbase, when addressing bugs and/or adding small features that don't require you to re-build a binary and re-distribute it through the respective app stores.
+CodePush SDK enables seamless in-app updates and serves as a core component of the [CodePush React Native SDK](https://github.com/Microsoft/react-native-code-push).
