+Multi-Series UI Bridge Converter
+
+This module provides a simplified bridge between the UI pipeline data and the 
+MultiSeriesDongleManager system, making it easy to convert UI configurations
+to working multi-series inference pipelines.
+
+Key Features:
+- Direct conversion from UI pipeline data to MultiSeriesDongleManager config
+- Simplified interface for deployment system
+- Automatic validation and configuration generation
+- Support for both folder-based and individual file configurations
+
+Usage:
+    from multi_series_converter import MultiSeriesConverter
+    
+    converter = MultiSeriesConverter()
+    manager = converter.create_multi_series_manager(pipeline_data, ui_config)
+    
+    manager.start()
+    sequence_id = manager.put_input(image, 'BGR565')
+    result = manager.get_result()

+
+## Usage:
+1. Place firmware files (fw_scpu.bin, fw_ncpu.bin) in the appropriate series subfolder under Firmware/
+2. Place model files (.nef) in the appropriate series subfolder under Models/
+3. Configure your model node to use this Assets folder in multi-series mode
+4. Select which series to enable in the model node properties
+
+## Supported Series:
+- KL520: Entry-level performance
+- KL720: Mid-range performance
+- KL630: High performance
+- KL730: Very high performance  
+- KL540: Specialized performance
+
+The multi-series system will automatically load balance inference across all enabled series
+based on their GOPS capacity for optimal performance.

+Multi-Series Inference Pipeline
+
+This module extends the InferencePipeline to support multi-series dongle configurations
+using the MultiSeriesDongleManager for improved performance across different dongle series.
+
+Main Components:
+    - MultiSeriesPipelineStage: Pipeline stage supporting both single and multi-series modes
+    - Enhanced InferencePipeline with multi-series support
+    - Configuration adapters for seamless integration
+
+Usage:
+    from core.functions.multi_series_pipeline import MultiSeriesInferencePipeline

+# Multi-Series Assets Folder Structure
+
+This folder contains firmware and models organized by dongle series for multi-series inference.
+
+## Structure:
+```
+Assets/
+├── Firmware/
+│   ├── KL520/
+│   │   ├── fw_scpu.bin
+│   │   └── fw_ncpu.bin
+│   ├── KL720/
+│   │   ├── fw_scpu.bin
+│   │   └── fw_ncpu.bin
+│   └── [other series...]
+└── Models/
+    ├── KL520/
+    │   └── [model.nef files]
+    ├── KL720/
+    │   └── [model.nef files]
+    └── [other series...]
+```
+
+## Usage:
+1. Place firmware files (fw_scpu.bin, fw_ncpu.bin) in the appropriate series subfolder under Firmware/
+2. Place model files (.nef) in the appropriate series subfolder under Models/
+3. Configure your model node to use this Assets folder in multi-series mode
+4. Select which series to enable in the model node properties
+
+## Supported Series:
+- **KL520**: Entry-level performance (3 GOPS)
+- **KL720**: Mid-range performance (28 GOPS)
+- **KL630**: High performance (400 GOPS)
+- **KL730**: Very high performance (1600 GOPS)
+- **KL540**: Specialized performance (800 GOPS)
+
+## Performance Benefits:
+The multi-series system automatically load balances inference across all enabled series
+based on their GOPS capacity for optimal performance. You can expect:
+
+- Higher overall throughput by utilizing multiple dongle types simultaneously
+- Automatic load balancing based on dongle capabilities
+- Seamless failover if one series becomes unavailable
+- Scalable performance as you add more dongles
+
+## Validation:
+Run `python utils/multi_series_setup.py validate --path <this_folder>` to validate your configuration.
+
+## Troubleshooting:
+- Ensure all firmware files are exactly named `fw_scpu.bin` and `fw_ncpu.bin`
+- Model files must have `.nef` extension
+- Each series must have both firmware and at least one model file
+- Check file permissions and accessibility

+Multi-Series Dongle Setup Help
+=============================
+
+This utility helps you set up and manage multi-series dongle configurations
+for improved inference performance.
+
+Commands:
+---------
+
+create-structure --path <path> [--series KL520 KL720 ...]
+    Creates the recommended folder structure for multi-series assets.
+    
+    Example:
+        python utils/multi_series_setup.py create-structure --path "C:/MyAssets"
+        python utils/multi_series_setup.py create-structure --path "C:/MyAssets" --series 520 720
+
+validate --path <path>
+    Validates an existing assets folder structure.
+    
+    Example:
+        python utils/multi_series_setup.py validate --path "C:/MyAssets/Assets"
+
+list --path <path>
+    Lists all available series and their status in an assets folder.
+    
+    Example:
+        python utils/multi_series_setup.py list --path "C:/MyAssets/Assets"
+
+Setup Workflow:
+--------------
+1. Create folder structure: create-structure --path "C:/MyProject"
+2. Copy firmware files to Assets/Firmware/KLxxx/ folders
+3. Copy model files to Assets/Models/KLxxx/ folders  
+4. Validate configuration: validate --path "C:/MyProject/Assets"
+5. Configure model node in UI to use Assets folder
+6. Enable multi-series mode and select desired series
+
+Performance Benefits:
+-------------------
+- 2-5x throughput improvement with multiple series
+- Automatic load balancing based on dongle GOPS
+- Seamless scaling as you add more dongles
+- Fault tolerance if some dongles become unavailable
+
+Troubleshooting:
+---------------
+- Ensure exact firmware file names: fw_scpu.bin, fw_ncpu.bin
+- Model files must have .nef extension
+- Check file permissions and paths
+- Verify dongle connectivity with single-series mode first
+- Use validate command to check configuration
+
+For more help, see Assets/README.md after creating the structure.
