 ### Obtaining and verifying the Facebook LLaMA original model and Stanford Alpaca model data
 
-* The LLaMA models are officially distributed by Facebook and will never be provided through this repository. See this [pull request in Facebook's LLaMA repository](https://github.com/facebookresearch/llama/pull/73/files) if you need to obtain access to the model data.
-* Please verify the sha256 checksums of all downloaded model files to confirm that you have the correct model data files before creating an issue relating to your model files.
-* The following command will verify if you have all possible latest files in your self-installed `./models` subdirectory:
