Practical example

A preview catches broken fences and heading levels before a README or changelog is published.

Frequently asked questions

Why does Markdown render differently elsewhere?

Different platforms support different Markdown extensions and sanitization rules.

Can I preview code blocks?

Yes. Fenced code blocks are useful for JSON, cURL, SQL and command examples.

Should I include secrets in documentation snippets?

No. Use placeholders and safe or fictional examples instead of real tokens or customer values.

Limitations / when not to use

Markdown flavors differ between platforms. GitHub, CMS tools and chat apps may render extensions differently.
