Where notices get rendered

[szepeviktor]

On the docsify-themeable demo page I see notices

!> **Important** notice with `inline code` and additional placeholder text used
to force the content to wrap and span multiple lines.

?> **Tip** notice with `inline code` and additional placeholder text used to
force the content to wrap and span multiple lines.

but cannot find the code that renders this Markdown to HTML.
Could you help me?
