If you have `Jinja2` installed, you can create Model Cards from a jinja template file. Let's see a basic example:  
```python
from pathlib import Path

from huggingface_hub import ModelCard, ModelCardData

# Define your jinja template
template_text = """
---
{{ card_data }}
---

# Model Card for MyCoolModel

This model does this and that.

This model was created by [@{{ author }}](https://hf.co/{{author}}).
""".strip()

# Write the template to a file
Path('custom_template.md').write_text(template_text)
