+## Acknowledgments
+
+This plugin was developed with inspiration from the excellent [Kodi SRG SSR addon](https://github.com/goggle/script.module.srgssr) by [@goggle](https://github.com/goggle). The Kodi addon served as a fantastic reference for understanding the SRG SSR API structure, authentication mechanisms, and handling of scheduled livestreams.
