+## Usage
 
-- package_name/ - Insert package code here
-- tests/ - Insert unit tests here
-- scripts/ - Insert scripts here
-- images/ - If this is CV/AI repository then insert images here
+### Dataset Structure
+Your dataset should be organized as follows:
+```
+dataset/
+├── images/           # Image files (.jpg, .png)
+│   ├── image1.jpg
+│   ├── image2.jpg
+│   └── ...
+├── labels/           # YOLO annotation files (.txt)
+│   ├── image1.txt
+│   ├── image2.txt
+│   └── ...
+└── classes.txt       # Class names (one per line)
+```
 
-# Package name
+### YOLO Annotation Format
+Each `.txt` file should contain detections in YOLOv5 format:
+```
+class_id x_center y_center width height
+```
+Where all coordinates are normalized (0.0-1.0).
 
-Write package short description here.
+### Running the Application
+```bash
+# Using the installed script
+sam-viewer --dataset /path/to/your/dataset
 
-# Installation : Developer
+# Or using Python module
+python -m ssya.sam_viewer.main --dataset /path/to/your/dataset
 
-Use poetry to install the package in development mode.
+# With verbose logging
+sam-viewer --dataset /path/to/your/dataset --verbose
+```
 
+### Basic Workflow
+1. **Load Dataset**: Start the application with your dataset path
+2. **Browse Images**: Use arrow buttons or navigate through the image list
+3. **Select Detection**: Click on a bounding box or select from the detection list
+4. **Find Similar**: Click "Find Similar Objects" to extract features and search
+5. **Filter Results**: Use the threshold slider to filter similarity results
+6. **Name Groups**: Save groups of similar objects with custom names
+
+## Application Interface
+
+### Main Window Components
+- **Image Display**: Shows current image with YOLO bounding boxes
+- **Navigation Controls**: Previous/Next buttons for browsing
+- **Detection List**: Lists all detections in current image
+- **SAM Controls**: Find similar, apply threshold, name objects
+- **Similarity Results**: Shows found similar objects
+- **Status Information**: Current operation status and statistics
+
+### Key Features
+- **Visual Feedback**: Selected detections are highlighted in yellow
+- **SAM Mask Overlay**: Generated masks are overlaid on images (orange with yellow contours)
+- **Filtered Navigation**: When threshold is applied, navigation is limited to matching images
+- **Progress Indication**: Background feature extraction shows progress

+## Example Output
+
+### Metadata Export
+When you name an object group, it saves to `dataset/output/{group_name}_group.json`:
+```json
+{
+  "group_name": "red_cars",
+  "created_at": "2024-01-15T10:30:00",
+  "threshold": 0.75,
+  "total_objects": 12,
+  "objects": [
+    {
+      "image_name": "image1.jpg",
+      "detection_index": 0,
+      "class_id": 1,
+      "class_name": "car",
+      "bbox": {
+        "x_center": 0.5,
+        "y_center": 0.6,
+        "width": 0.2,
+        "height": 0.3
+      },
+      "similarity_score": 0.87
+    }
+  ]
+}

-# Release
+## Contributing
 
-Github workflow is created to automatically release the package to PyPI when a new tag "vX.X.X" (example v1.0.0) is pushed to the main branch. 
+1. Fork the repository
+2. Create a feature branch
+3. Add tests for new functionality
+4. Ensure all tests pass
+5. Submit a pull request
 
-```bash
-git tag vX.X.X
-git push --tags
-```
+## Future Integration
 
-Or manually build and upload the package to PyPI using the following command.
+The application is designed to easily integrate with real SAM2 models. To replace the mock implementation:
 
-```
-uv build
-```
+1. Install SAM2 dependencies
+2. Update `sam_interface.py` to use real SAM2 models
+3. Replace mock prediction methods with actual SAM2 calls
