# Show the chat

This guide instructs you on how to show your chat app.

## Check chat availability

 Note:
Before showing the chat make sure you have initialized this SDK and executed the `setIdentity` method.

To check if the chat is available, use the following method:


```kotlin
// Possible errors:
// - sdk_not_initialized - means that you need to perform `initialize` method firstly and then `setIdentity`.
// - chat_already_started - means that you cannot have two chats opened.

fun isChatAvailable(): Result<Unit>
```

## Display the Chat app

To start the chat, use the `start` method in `SinchChatSDK.chat.*`:


```kotlin
fun start(context: Context): Result<Unit>
```

The result will return information if the chat was shown correctly:


```kotlin

do {

val result = SinchChatSDK.chat.start(this)
if (result.isFailure) {
   // do some things.
}
```

You may now set up [push notifications]((/docs/sinch-chat/getting-started/android/push/), if desired.
