To upload files, you must use a token. By default, the token saved locally (using `huggingface-cli login`) will be used. If you want to authenticate explicitly, use the `--token` option:  
```bash
>>> huggingface-cli upload Wauplin/my-cool-model ./models . --token=hf_****
...
https://huggingface.co/Wauplin/my-cool-model/tree/main
```
