Generally .lit is backward compatible with Markdown. That is to say that a valid Markdown file is a valid .lit file and vice versa.
The primary difference being that a basic/normal Markdown viewer will lack many of the niceties afforded by .lit but the intent is that it should still render correctly for the reader.

Key differences
Frontmatter
We consider existing frontmatter implementations Not backward compatable with basic Markdown. Primarily due to the fact that they are rendered at all (and badly) by renderers that do not support frontmatter. Therefor we define frontmatter as HTML Comments with a data prefix.
<!-- data
title: foo

Code block meta
```lang [...meta]
