+# Gemma 3 Sales Coach 🎯
+
+Fine-tuned **Gemma 3 270M IT** model for sales conversation coaching.
+
+## Model Description
+
+This model analyzes sales conversations and provides detailed coaching feedback, identifying:
+- **Sales rep mistakes** with specific turn numbers
+- **Why each mistake is problematic** 
+- **Better alternative responses**
+- **Impact on conversion probability**
+
+## Training Data
+
+- **Dataset**: 99,056 synthetic sales conversations with coaching annotations
+- **Industries**: 60+ industries covered
+- **Personas**: 20+ buyer personas
+- **Outcomes**: Lost deals, stalled deals, weak commitments
+
+## Usage
+
+```python
+from transformers import AutoModelForCausalLM, AutoTokenizer
+
+model = AutoModelForCausalLM.from_pretrained("NandhaKishorM/gemma3-sales-coach")
+tokenizer = AutoTokenizer.from_pretrained("NandhaKishorM/gemma3-sales-coach")
+
+# Format your conversation
+conversation = '''[Turn 1] Sales Rep: Hi, I'm calling about our software...
+[Turn 2] Prospect: We're not interested right now.
+[Turn 3] Sales Rep: But our product is the best...
+
+Where did I make mistakes and how can I improve?'''
+
+inputs = tokenizer(conversation, return_tensors="pt")
+outputs = model.generate(**inputs, max_new_tokens=512)
+print(tokenizer.decode(outputs[0]))
+```
+
+## Training Details
+
+- **Base Model**: google/gemma-3-270m-it
+- **Method**: LoRA fine-tuning
+- **LoRA Rank**: 32
+- **Epochs**: 5
+- **Hardware**: 2x NVIDIA T4 GPUs
+
+## Limitations
+
+- Optimized for B2B sales conversations
+- Best results with 10+ turn conversations
+- English language only
+
+## License
+
+Apache 2.0 (same as base Gemma model)
