markdown-toc

Quick answer: Generate a linked table of contents from any Markdown document's headings. Open markdown-toc — everything runs locally in your browser, and files never leave your device.

Steps

1. Paste the Markdown into the TOC generator.
2. Choose heading depth (## and ### usually).
3. Paste the generated list at the top of your document.

Important notes

• Anchor slugs differ across platforms — GitHub lowercases and hyphenates; Chinese headings follow platform-specific rules, so click-test after publishing.
• Regenerate the TOC after heading edits; do it last, before publishing.

Common questions

Auto-maintaining? Static-site plugins can; this tool targets one-shot generation and GitHub READMEs.

Depth too deep? Two or three levels stay readable.

When to use this

For documentation sites, a sticky TOC generated at build time is usually better; use this tool for READMEs and one-off documents.
