Output from a script to markdown?

Hello,

I have a fairly simple question. I was looking for a Marketplace Action or way through GitHub Actions to create some very basic markdown visible in the summary of the running job of output produced from a simple run (as part of a step) from a job (e.g, Python script output) or simply log to markdown. Is this possible through workflow? Can anyone point me to an example? My goal is just yoink output from a run step and make it more visible.
