article="""### How it works
- The predictor uses machine learning trained on historical RD2L draft data
- Player statistics are fetched from OpenDota API
- Position comfort levels range from 1 (least comfortable) to 5 (most comfortable)
- Predictions are based on both current stats and historical performance
### Notes
- MMR should be the player's current solo MMR
- Position comfort should reflect actual role experience
- Predictions are estimates and may vary from actual draft results"""
