+sudo apt install git-lfs
+git lfs install

 ollama list  # View locally available LLMs
 export RUN_IN_OFFLINE_MODE=True  # Enable the offline mode to use Ollama
 git clone https://github.com/barun-saha/slide-deck-ai.git
 cd slide-deck-ai
+git lfs pull  # Pull the PPTX template files

 python -m venv venv  # Create a virtual environment
 source venv/bin/activate  # On a Linux system
 pip install -r requirements.txt
