A .md file with character < and { will cause error.
It has been detail from astro docs: https://docs.astro.build/en/guides/markdown-content/#escaping-special-characters

@TongDucThanhNam Thank you for the find, I will add fixing this to the Roadmap.

FYI, I plan on separating AstroNot into a separate NPM package, that way it can be installed independently into any Astro project. The web portion will be moved to the AstroNotStarter package.
