# Quick Start

To start using app inbox, you need to:

* Enable App Inbox
* Integrate Client SDKs
* Use Signed Identity

## Enable App Inbox

Go to the [applications](/api/client-sdks/applications.md) dashboard. If you haven't created at application yet, go ahead and create one. Then enable App Inbox on the application as shown in the image below.

## Integrate Client SDKs

You can use app inbox via one of Bird client sdks: [Android SDK](/api/client-sdks/sdk-integration/android-sdk.md), [Swift SDK](/api/client-sdks/sdk-integration/swift-sdk.md), or [Web SDK](/api/client-sdks/sdk-integration/web-sdk.md). If you haven't integrated one of them in your application code, go ahead and do that now.

## Use Signed Identity

For App Inbox to work, you must identify your contacts using [Signed Identity](/api/client-sdks/contact-profiles/signed-identity.md). Signed Identity is a secure way to identify contacts paving the way to a secure access to App Inbox.
