+# Where to find the models?
+
+You can find llama v2 models on HuggingFace hub [here](https://huggingface.co/meta-llama), where models with `hf` in the name are already converted to HuggingFace checkpoints so no further conversion is needed. The conversion step below is only for original model weights from Meta that are hosted on HuggingFace model hub as well.

 # Model conversion to Hugging Face
 The recipes and notebooks in this folder are using the Llama 2 model definition provided by Hugging Face's transformers library.
