-```markdown
 ## 📂 CSV Format
 
 The CSV file must contain the following columns:
 
+```text
 text,rating,helpful_vote,verified_purchase
-
+```
 
 ## 🎯 Project Goals
 
-- Achieve **greater than 80% classification accuracy** on unseen test data  
-- Develop a **fully offline, locally runnable web application**  
-- Support both **single review prediction and batch CSV processing**  
-- Provide **fake probability scores for each prediction** 
-- Follow an **Agile development methodology with iterative improvements**  
-- Ensure **fast response time and user-friendly interface**

 ## 📂 Dataset
 
 ### Label Definition
 
-- `1` → Fake review  
-- `0` → Genuine review  
-
-Note: The model uses binary classification where 1 represents fake and 0 represents genuine.

-
+* `1` → Fake review
+* `0` → Genuine review
 
+The system uses binary classification where `1` represents a fake review and `0` represents a genuine review.

+## ⚠️ Risk and Validation
 
+To reduce data leakage and improve reliability, the project includes:
 
-⚠️ Risk & Validation
-- To avoid data leakage:
-- Text normalization + hashing
-- Duplicate-safe splitting
-- Near-duplicate audit
-- Remaining Risk
-- Paraphrased reviews may still exist → residual risk
+* Text normalization and hashing
+* Duplicate-safe splitting
+* Near-duplicate audit
 
-## ⚙️ CI/CD
+### Remaining Risk
 
-- GitHub Actions used  
-- Automated testing on every push  
+* Paraphrased reviews may still exist in the dataset, creating residual risk
