How do I export in Markdown format?

[maxin9966]

I intend to use this tool for formatted document layout, as long as it can distinguish between headings of different sizes.
Is there a way to achieve this?

This cannot currently distinguish between different levels of heading. I recommend looking at marker for markdown - https://github.com/VikParuchuri/marker . I will hopefully soon add a hierarchy of sections there
