+
+## 🔍 What this means
+
+This project uses **YOLOv8 pretrained on the COCO dataset**, which contains **ONLY 80 object classes**.
+
+Therefore, the system can **only detect known COCO objects**.
+
+---
+
+## ✅ Detectable COCO Objects (Examples)
+
+✔ person  
+✔ car / bus / truck  
+✔ dog / cat / horse  
+✔ bottle / cup / bowl  
+✔ fork / knife / spoon  
+✔ laptop / tv / keyboard / mouse  
+✔ apple / banana / orange  
+✔ chair / couch / bed  
+✔ microwave / oven / sink / refrigerator  
+
+---
+
+## ❌ NOT Detectable (Not part of COCO dataset)
+
+The model **will NOT detect these objects correctly**:
+
+- whisk  
+- spatula  
+- ladle  
+- tongs  
+- Indian kitchen utensils  
+- toys  
+- makeup products  
+- stationery items  
+- cartoon / clipart images  
+- uncommon tools and objects  
+
+> 🟥 These objects do *not* exist in COCO dataset → YOLO guesses incorrectly.
+
+---
+
+## 🛠️ Want to detect your own objects?
+
+You must train a **custom YOLO model**.
+
+> ✔ Custom training guide available  
+> ✔ Works with your utensils, cosmetics, tools, toys  
+> ✔ 10× better accuracy for non-COCO items  
+

+
+## ⚙️ Configuration
+
+Edit `config.py` to customize behavior:
+
+### Model Settings
+
+```python
+MODEL_NAME = "yolov8n.pt"      # Options: yolov8n/s/m/l/x.pt
+CONFIDENCE_THRESHOLD = 0.25    # Detection confidence (0.0-1.0)
+IOU_THRESHOLD = 0.45           # Intersection over Union threshold
+DEVICE = "cuda"                # "cuda" for GPU, "cpu" for CPU
+```
+
+### Detection Settings
+
+```python
+# Enable/disable features
+ENABLE_COUNTING = True
+ENABLE_ZONE_ALERT = True
+
+# Classes to count
+COUNT_TARGET_CLASSES = ["person", "car", "bicycle"]
+
+# Define restricted zone (polygon coordinates)
+ZONE_POLYGON = [(50,50), (400,50), (400,300), (50,300)]
+
+# Classes that trigger zone alerts
+ALERT_CLASSES = ["person"]
+```
+
+### Output Settings
+
+```python
+OUTPUT_DIR = "outputs/detections"
+SAVE_VIDEO = True
+VIDEO_FPS = 20
+```

+    Display & Save Output
+```
+
+### Zone Alert System
+
+1. **Define Zone**: Set polygon coordinates in `config.py`
+2. **Track Objects**: System monitors object centers
+3. **Alert Trigger**: When specified class enters zone
+4. **Visual Feedback**: Red alert overlay on frame
+
+### Object Counting
+
+- Counts objects per frame by class
+- Cumulative counting across video
+- Configurable target classes
+- Real-time overlay display
+
+---
+
+## 🎓 Detected Object Classes
