Hi @FerrariFlunker  
Here’s in an example of of an official plugin which uses a local copy of the `holidays` gem. I think you can use a similar pattern in your case.

> **[discourse-calendar/vendor/holidays at main · discourse/discourse-calendar](https://github.com/discourse/discourse-calendar/tree/main/vendor/holidays)**
>
> main/vendor/holidays

Here’s how its included.
