    In this format we have multiple frontmatters and content sections, each defining a message. The idea here is to use jinja formatting in a promt.md.jinja file to make the markdown, and jinja formatting obvious

    e.g.
        ---
        role: system
        ---
        Be good
        ---
        role: user
        ---
        What is the meaning of life?
