Syntax highlighting in README.md

[Codelica]

Describe the solution you'd like
Would like to see code block syntax highlighting ala GitHub and GitLab:

console.log(`This is JavaScript!`);

# This is YAML!
web:
  scope: \@something

Thanks for considering :)

I think that's doable and +1 from me, you can work on the new readme project to improve the parsing Markdown to HTML.
