 ## Introduction
 
+We are introducing a new version of the Sendbird UIKit. Version 3 features a new modular architecture with more granular components that give you enhanced flexibility to customize your web and mobile apps. Check out our [migration guides](/changelogs/MIGRATIONGUIDE_V3.md) and download [our samples](https://github.com/sendbird/sendbird-uikit-android/tree/v3-beta/uikit-sample)

 Sendbird UIKit for Android is a development kit with an user interface that enables an easy and fast integration of standard chat features into new or existing client apps. This repository houses the UIKit source code in addition to two samples as explained below. 
 
 - **uikit** is where you can find the open source code. Check out [UIKit Open Source Guidelines](https://github.com/sendbird/sendbird-uikit-android-sources/blob/main/OPENSOURCE_GUIDELINES.md) for more information regarding our stance on open source.
-- **uikit-sample** is a chat app with UIKit’s core core features in which you can see items such as push notifications, total unread message count and auto sign-in are demonstrated. When you sign in to the sample app, you will only see a list of channels rendered by the [ChannelListActivity](https://sendbird.com/docs/uikit/v1/android/guides/group-channel#2-list-channels) on the screen.

 ### Try the sample app using your data 
 
-If you would like to try the sample app specifically fit to your usage, you can do so by replacing the default sample app ID with yours, which you can obtain by [creating your Sendbird application from the dashboard](https://docs.sendbird.com/android/quick_start#3_install_and_configure_the_chat_sdk_4_step_1_create_a_sendbird_application_from_your_dashboard). Furthermore, you could also add data of your choice on the dashboard to test. This will allow you to experience the sample app with data from your Sendbird application.
