+                ### CLI:

-            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
-            ```
