# Set the Chat SDK Theme

If you want to use a custom theme for Chat SDK you need to make sure your theme inherits from the ChatSDKTheme:

Open your App's theme file in `res -> values -> styles.xml`

```
<resources>
    <style name="AppTheme" parent="ChatSDKTheme">
    </style>
</resources>
```

Then you need to disable the default Chat SDK theme:

```
UIModule.config().overrideTheme();
```

If you want to use a completely separate theme for Chat SDK then your main project, make a new theme that has the `ChatSDKTheme` as it's parent.

Then tell Chat SDK to use that theme:

```
UIModule.config().setTheme(R.style.CustomChatSDKTheme);
```
