## How to Import Your Own BDF Fonts

BDF (Bitmap Distribution Format) is the standard text format for bitmap fonts. You can import any open-source BDF font:

1. Export a BDF font from a font editor or find one on GitHub
2. Use the BDF parser to convert to Glyphon's JSON format
3. Add to the **Open Source** library section

### Example: Adding a Custom Font

```bash
python3 assets/fonts-source/bdf-to-json.py your-font.bdf your-font.json "My Font Name"
```

This generates a JSON file that Glyphon can load.
