 - Follow Astral uv installation instructions first: https://docs.astral.sh/uv/
 - Typical flow (after `uv` is installed and you are in the project directory):
 
-  # create and install dependencies from pyproject.toml using uv
+```
 
   uv pip install -r pyproject.toml
 
   uv run python ./main.py

 Notes:
 - The exact `uv` subcommands depend on the uv version/configuration. Check the Astral uv docs for the exact syntax for your uv CLI release. The analyzer only needs a Python executable in the venv to run `python -m pip list --format=json`; `uv` typically provides or creates that venv.
 
 ### Using plain virtualenv / pip (fallback)
-- Create a virtual environment and install dependencies listed in `pyproject.toml` with your preferred tool.
