# marp-share

Collaborative **Marp** editing — *Overleaf + Google Slides for Markdown*.

Open this page in a second window to see **real-time** editing. ✍️

---

## How it works

- Type Markdown on the **left** — everyone sees it instantly
- Slides render **live** on the right
- Coloured cursors show who is editing where

---

## Code & math render too

\`\`\`python
def greet(name: str) -> str:
    return f"Hello, {name}!"
\`\`\`

$$ e^{i\\pi} + 1 = 0 $$

---

## Roadmap

1. ✅ Real-time multi-cursor (Yjs)
2. Git-backed persistence + history
3. Sign in with Hugging Face
4. Comments + PDF / PPTX export
