-## Tasks
-- [x] Remove duplicate session_start() in index.php (keep the one at the top)
-- [x] Remove one duplicate session_start() in terms.php at the top
-- [x] Consolidate session_start() calls in forgotpswd.php to have only one at the beginning
-- [x] Test affected pages for session functionality
-- [x] Verify no other files have duplicate session_start() calls
+# Real-Time Order Tracking Implementation
+
+## Database Changes
+- [x] Add 'status' field to orders table (ALTER TABLE orders ADD COLUMN status VARCHAR(50) DEFAULT 'Placed')
+
+## Backend Updates
+- [x] Modify save_checkout.php to set initial order status
+- [x] Create update_order_status.php API endpoint for status updates

+
+## Testing
+- [x] Test database changes and order flow
+- [x] Test real-time updates
+- [x] Test notifications
+
+## Summary
+✅ **Real-Time Order Tracking Implementation Complete!**
+
+**Features Implemented:**
+- Database schema updated with order status tracking
+- Order status progression: Placed → Preparing → Ready for Delivery → Out for Delivery → Delivered
