 ### Method 3: Using ComfyUI Inference
 
-TODO - To be added ComfyUI integration guide
+This guide will instruct you on how to download and use the portable version of the Lightx2v-ComfyUI environment, so you can avoid manual environment configuration steps. This is suitable for users who want to quickly start experiencing accelerated video generation with Lightx2v on Windows systems.
+
+#### Download the Windows Portable Environment:

+- [Baidu Cloud Download](https://pan.baidu.com/s/1FVlicTXjmXJA1tAVvNCrBw?pwd=wfid), extraction code: wfid
+
+The portable environment already packages all Python runtime dependencies, including the code and dependencies for ComfyUI and LightX2V. After downloading, simply extract to use.
+
+After extraction, the directory structure is as follows:
+
+```shell
+lightx2v_env
+├──📂 ComfyUI                    # ComfyUI code
+├──📂 portable_python312_embed   # Standalone Python environment
+└── run_nvidia_gpu.bat            # Windows startup script (double-click to start)
+```
+
+#### Start ComfyUI
+
+Directly double-click the run_nvidia_gpu.bat file. The system will open a Command Prompt window and run the program. The first startup may take a while, please be patient. After startup is complete, the browser will automatically open and display the ComfyUI frontend interface.
