Thanks for sharing!

How did you pre-train this model (infrastructure, number of epochs, etc.)?
Do you have eval results on downstream tasks?

Also you can add a  
```

language: greek

```
tag to the top of the file

I'll merge this in the meantime, thanks for sharing!

I just amended the initial model card with extra information on the pre-training process. No evaluation yet, I hope will have some experiments, pretty soon. Thanks!
