## Integration

We provide open-source DRM integrations which are easy to maintain and allow for a modular approach. You can find them in the [DRM integration samples repository](https://github.com/THEOplayer/samples-drm-integration), alongside guides on how to integrate and use them.

The Arris Titanium integration can be found [here](https://github.com/THEOplayer/samples-drm-integration/blob/master/ios/ContentProtectionIntegration/integration/ArrisTitaniumDrmIntegration.swift).

## Code example

Please refer to [DRM](https://optiview.dolby.com/docs/theoplayer/how-to-guides/ios/drm/introduction.md) (custom configuration).
