# Getting started

## Usage

1. Follow [our Getting Started guide](https://optiview.dolby.com/docs/theoplayer/getting-started/sdks/ios/getting-started.md) to set up THEOplayer in your iOS app.
2. Add an OptiView Live source to your player's source.

### Add an OptiView Live source

After setting up your THEOplayer in your app, set its source to a `SourceDescription` containing a `TheoLiveSource`. You'll need an OptiView Live channel ID:

```swift
theoplayer.source = SourceDescription(source: TheoLiveSource(channelId: "3aa5qylwwk7gijsobayq09yee"))
```
