+To use llama.cpp, you need to prepare a gguf format model file, and there are two common ways to obtain it, you can choose either:
 
 1. Download a pre-converted model file.
 
-Suppose you want to use [Vicuna 7B v1.5](https://huggingface.co/lmsys/vicuna-7b-v1.5), you can download the file already converted from [TheBloke/vicuna-7B-v1.5-GGML](https://huggingface.co/TheBloke/vicuna-7B-v1.5-GGML), only one file is needed. Download it to the `models` directory and rename it to `ggml-model-q4_0.bin`.

 2. Convert It Yourself
 
-You can convert the model file yourself according to the instructions in [llama.cpp#prepare-data--run](https://github.com/ggerganov/llama.cpp#prepare-data--run), and put the converted file in the models directory and rename it to `ggml-model-q4_0.bin`.
