Enhance installation documentation with detailed explanations

- Add comprehensive explanation of both installation scripts
- Clearly distinguish between regular and portable ComfyUI installations
- Document Python environment requirements for each script
- Explain automatic detection mechanisms for embedded Python
- Detail folder name independence and path detection
- Provide clear usage guidelines for each installation type
- Address user feedback about insufficient documentation

 2. Ensure you have the official ComfyUI-nunchaku plugin installed (which includes nunchaku as a dependency).
 
-3. **Run the installation script:**
-   - **For regular ComfyUI installations**: Double-click `install_qwen_lora.bat`
-   - **For portable ComfyUI installations with embedded Python**: Double-click `install_qwen_lora_portable.bat`
-   - This script will automatically modify the ComfyUI-nunchaku `__init__.py` file
-   - Restart ComfyUI
+3. **Choose the appropriate installation script based on your ComfyUI setup:**
+
+#### For Regular ComfyUI Installations
+- **Script**: `install_qwen_lora.bat`
+- **Python Environment**: Uses global Python environment (system-installed Python)
+- **Requirements**: Python must be installed and accessible from command line (`python` command)
+- **Usage**: Double-click `install_qwen_lora.bat`
+- **When to use**: Standard ComfyUI installations where Python is installed globally
+
+#### For Portable ComfyUI Installations with Embedded Python
+- **Script**: `install_qwen_lora_portable.bat`
+- **Python Environment**: Uses embedded Python (`python_embeded` folder)
+- **Requirements**: ComfyUI installation with `python_embeded` folder containing `python.exe`
+- **Usage**: Double-click `install_qwen_lora_portable.bat`
+- **When to use**: Portable ComfyUI installations that include embedded Python
+- **Automatic Detection**: Script automatically searches for `python_embeded` in multiple locations:
+  - `[ComfyUIFolder]/ComfyUI/python_embeded/python.exe`
+  - `[ComfyUIFolder]/python_embeded/python.exe` (most common)
+- **Folder Name Independence**: Works with any ComfyUI folder name (not limited to "ComfyUI")
+
+4. **After running the installation script:**
+   - The script will automatically modify the ComfyUI-nunchaku `__init__.py` file
+   - Restart ComfyUI to use the new LoRA loader nodes

+**Both batch files automatically add the integration code to your ComfyUI-nunchaku `__init__.py` file:**
 
-1. **What the batch file does:**
-   - Automatically detects your ComfyUI installation path
-   - Backs up the original `__init__.py` file (creates `__init__.py.backup`)
-   - Adds the exact import code shown above to the end of ComfyUI-nunchaku's `__init__.py`
-   - Performs error checking to ensure all required files exist
-   - Provides user feedback throughout the process
+#### What the installation scripts do:
+- **Path Detection**: Automatically detects your ComfyUI installation path using relative path calculation
+- **Backup Creation**: Backs up the original `__init__.py` file (creates `__init__.py.backup`)
+- **Code Integration**: Adds the exact import code shown above to the end of ComfyUI-nunchaku's `__init__.py`
