-> Currently, the files are not updated with the latest tokens. The developer [https://github.com/dtankdempse/](https://github.com/dtankdempse/) is currently migrating to an alternative solution.
-> Stay tuned.
+> [!WARNING]  
+> In december 2024, the developer [https://github.com/dtankdempse/](https://github.com/dtankdempse/) stopped working on his version of the main TVApp grabber, which this branch depended on and caused our docker image to become useless.
+> After 2024, our container was completetly re-developed from the ground up to handle all of the playlist and xml generation in-house.
+>
+> This branch serves as an archive for the original version, however, it no longer works.
+>
+> To get the most recent working build, visit the [main](https://github.com/TheBinaryNinja/tvapp2/tree/main) branch.
