Frequently asked questions

Does it support heading levels past ###?

No — only single #, ##, and ### headings are recognized, since each pattern requires an exact hash count immediately followed by a space. A #### heading or deeper just renders as plain text with the hash marks still visible.

Can I write numbered lists?

Not currently — only lines starting with "- " convert into list items. A numbered line like "1. " isn't recognized as a list and renders as plain text instead.

Is HTML I paste into the Markdown sanitized before it's rendered?

No — the preview renders through dangerouslySetInnerHTML with no sanitization step, so any raw HTML tags in your input pass straight through and render as actual HTML rather than being escaped.
