+            
+            ## Use with llama.cpp
+            Install llama.cpp through brew (works on Mac and Linux)
+            
+            ```bash
+            brew install llama.cpp
+            
+            ```
+            Invoke the llama.cpp server or the CLI.
+            
+            ### CLI:
+            ```bash
+            llama-cli --hf-repo {new_repo_id} --hf-file {quantized_gguf_name} -p "The meaning to life and the universe is"
+            ```
+            
+            ### Server:
+            ```bash
+            llama-server --hf-repo {new_repo_id} --hf-file {quantized_gguf_name} -c 2048
+            ```
+            
+            Note: You can also use this checkpoint directly through the [usage steps](https://github.com/ggerganov/llama.cpp?tab=readme-ov-file#usage) listed in the Llama.cpp repo as well.
+
+            Step 1: Clone llama.cpp from GitHub.
+            ```
+            git clone https://github.com/ggerganov/llama.cpp
+            ```
+
+            Step 2: Move into the llama.cpp folder and build it with `LLAMA_CURL=1` flag along with other hardware-specific flags (for ex: LLAMA_CUDA=1 for Nvidia GPUs on Linux).
+            ```
+            cd llama.cpp && LLAMA_CURL=1 make
+            ```
+
+            Step 3: Run inference through the main binary.
+            ```
+            ./llama-cli --hf-repo {new_repo_id} --hf-file {quantized_gguf_name} -p "The meaning to life and the universe is"
+            ```
+            or 
+            ```
+            ./llama-server --hf-repo {new_repo_id} --hf-file {quantized_gguf_name} -c 2048
