 # Initial download of model files
 
 ### 1. Download the Model from Hugging Face

 Use a Python Script to Download Model Files from Hugging Face

 ```bash
 pip install huggingface_hub
 wget https://github.com/opendatalab/MinerU/raw/master/docs/download_models_hf.py -O download_models_hf.py
 python download_models_hf.py
 ```
+
 The Python script will automatically download the model files and configure the model directory in the configuration file.
 
 The configuration file can be found in the user directory, with the filename `magic-pdf.json`.

 ## 1. Models downloaded via Git LFS
 
->Due to feedback from some users that downloading model files using git lfs was incomplete or resulted in corrupted model files, this method is no longer recommended.

 If you previously downloaded model files via git lfs, you can navigate to the previous download directory and use the `git pull` command to update the model.
