+[CodePush](https://microsoft.github.io/code-push) is a cloud service that enables Cordova and 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 SDKs for [Cordova](http://github.com/cordova-plugin-code-push) and [React Native](http://github.com/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.
+
+This repo includes the [management CLI](http://microsoft.github.io/code-push/docs/cli.html) as well as some shared code that is used by both the Cordova and React Native client SDKs. To get started, refer to our [documentation](http://microsoft.github.io/code-push/index.html#getting_started).
