Overview

This project is a standalone HTML file containing:

• A Markdown editor area with live preview.

• Export as .md or .html.
• Local file open/save support (works in modern browsers).
• Minimal dependencies — no build step required.

Features

• Live preview using a Markdown parser (e.g., marked.js) bundled into the single file.
• Export and import .md files using browser APIs.
• Simple UI, keyboard shortcuts, and responsive layout.
• Optional localStorage autosave.

Usage

1. Open editor.html in a modern browser:

file:///path/to/editor.html

or host via a static server:

python3 -m http.server 8000
# then open http://localhost:8000/editor.html

2. Use the toolbar or keyboard shortcuts to edit.
3. Click “Export” to download .md or .html.

Customization

• The single-file nature makes it easy to drop into any project, embed into a static website, or use as a simple note-taking tool.
• Replace the bundled markdown parser if you prefer a different one (instructions inside the file).
