To use Docling, simply install `docling`from your package manager, e.g. pip: `pip install docling`

To convert individual documents with python, use `convert()`, for example:

    from docling.document_converter import DocumentConverter

    source = "https://arxiv.org/pdf/2408.09869"
    converter = DocumentConverter()
    result = converter.convert(source)
    print(result.document.export_to_markdown())

The program will output: `## Docling Technical Report[...]`

Prefetch the models:

- Use the `docling-tools models download` utility:
- Alternatively, models can be programmatically downloaded using `docling.utils.model_downloader.download_models()`.
- Also, you can use download-hf-repo parameter to download arbitrary models from HuggingFace by specifying repo id:

                  $ docling-tools models download-hf-repo ds4sd/SmolDocling-256M-preview
                  Downloading ds4sd/SmolDocling-256M-preview model from HuggingFace...

      $ docling-tools
