Via pandoc you can get outputs that are close to the current ffv1.html and 
ffv1.pdf outputs of ffv1.lyx.

pandoc --mathml -s --number-sections ../ffv1.md -c lyx.css -o ffv1.html
pandoc -s --number-sections ../ffv1.md --latex-engine=xelatex -V 
geometry:margin=1in -o ffv1.pdf

I can move this info to a readme.

We didn't test with markdown_py but were mostly working with pandoc.

This is possible. Here is the markdown file:
