```Frequently asked questions
Which flavor of Markdown is supported?
Roughly GitHub-flavored Markdown (GFM): headers, lists, tables, code blocks with language hints, fenced code, autolinks, strikethrough. We do not parse HTML inside Markdown.
Can I copy the HTML output?
Yes — the rendered HTML is in the right pane and can be copied. It is plain HTML, no React-specific markup.
Is GitHub README rendered the same way?
Very close. GitHub adds task lists ([ ] / [x]) and emoji shortcodes (:smile:) that may render slightly differently here.
