+```
+npm install jsonrepair
+```
 
-Inference of Meta's [LLaMA](https://arxiv.org/abs/2302.13971) model (and others) in pure C/C++
+3. Download a compatible gguf model:
+For example:
+```
+wget https://huggingface.co/sanjay920/Llama-3-8b-function-calling-alpha-v1.gguf/resolve/main/Llama-3-8b-function-calling-alpha-v1.gguf
+```
 
-> [!IMPORTANT]
-[2024 Jun 12] Binaries have been renamed w/ a `llama-` prefix. `main` is now `llama-cli`, `server` is `llama-server`, etc (https://github.com/ggerganov/llama.cpp/pull/7809)
+4. start server:
+```
+./llama-server -ngl 35 -m Llama-3-8b-function-calling-alpha-v1.gguf   --port 1234 --host 0.0.0.0  -c 16000 --chat-template llama3
