-### 📋 How it works:
-1.  Choose a dataset from Hugging Face Hub.
-2.  The Ultra-FineWeb classifier will score each text sample.
-3.  View quality distribution and download the scored dataset.
-4.  Optionally, upload the results to a new repository on your Hugging Face account.
-
-**Note:** The first run will download the model (~347MB), which may take a moment.
