+# Loan Default Prediction
+
+## Description
+A machine learning model to predict whether a loan applicant is likely to default on their loan. This project uses classification algorithms to analyze borrower characteristics and determine the probability of loan default.

+
+## Dataset
+The dataset contains loan application information including:
+- Borrower demographics (age, income, employment status)
+- Loan characteristics (amount, term, interest rate)
+- Credit history (credit score, past defaults)
+- Financial ratios (debt-to-income ratio)
+
+## Installation
+```bash
+pip install -r requirements.txt
+```
+
+## Usage
+```python
+from src.model import LoanDefaultPredictor
+
+predictor = LoanDefaultPredictor()
+predictor.load_model('models/loan_default_model.pkl')
+prediction = predictor.predict(loan_data)
+```
+
