+# BugFlow Severity Classifier
+
+Fine-tuned CodeBERT model for classifying bug report severity levels.
+
+## Labels
+- **Low**: Minor issues, cosmetic changes
+- **Medium**: Standard bugs affecting some functionality
+- **High**: Important bugs affecting major functionality  
+- **Critical**: System crashes, data loss, security issues
+
+## Usage
+
+```python
+from transformers import RobertaTokenizer, RobertaForSequenceClassification
+import torch
+
+model = RobertaForSequenceClassification.from_pretrained("YOUR_USERNAME/bugflow-severity-classifier")
+tokenizer = RobertaTokenizer.from_pretrained("YOUR_USERNAME/bugflow-severity-classifier")
+
+text = "Application crashes when clicking login button"
+inputs = tokenizer(text, return_tensors="pt", truncation=True, padding=True)
+outputs = model(**inputs)
+probs = torch.softmax(outputs.logits, dim=1)
+labels = ['low', 'medium', 'high', 'critical']
+predicted = labels[torch.argmax(probs).item()]
+print(f"Severity: {predicted}")
+```
+
+## Training
+- Base model: microsoft/codebert-base
+- Dataset: Custom GitHub issues dataset + domain-specific bugs
+- Fine-tuned using Hugging Face Transformers
