+# MedInjection-FR — Native Subset 🇫🇷
+
+## Summary
+
+The **Native** component of **MedInjection-FR** comprises **French biomedical instructions and question–answer pairs** natively written in French.  
+It forms the core of the dataset and reflects **authentic medical reasoning and linguistic formulations**, sourced from curated corpora such as *FrBMedQA*, *FrenchMedMCQA*, and *MediQAl*.
+
+This subset serves as the **high-quality reference supervision** for instruction tuning of large language models (LLMs) in French biomedical contexts.
+
+## Motivation
+
+Instruction tuning has become essential for adapting LLMs to domain-specific prompts. Yet, in medicine, **native French supervision remains scarce**.  
+The Native subset bridges this gap, providing instruction–response data derived directly from **French medical exams, textbooks, and clinical resources**, preserving authentic phrasing, domain structure, and context.
