About converting Markdown to HTML in the browser
Markdown → HTML turns notes and README-style drafts into HTML source as you type. Headings, lists, links, emphasis, and common GFM extras become tags you can paste into a CMS or template. This is source, not a rendered reading pane — Markdown Preview is the sibling when you want to see the page. HTML is not sanitized for every host; untrusted Markdown should still be treated carefully before you publish.
Worked example: # Title plus a bullet list becomes an h1 and a ul. A fenced code block becomes a pre/code pair. This is not a full GitHub clone and not a collaborative editor.
