# QuickLook — Quick Start

## What It Does

Press **Space** on any `.md` file in Finder to see a beautifully rendered preview — powered by the same mdfy.cc rendering engine.

## Install

QuickLook is automatically installed when you install the mdfy Mac app:

1. Install mdfy for Mac from [mdfy.cc/plugins](https://mdfy.cc/plugins)
2. On first launch, the QuickLook extension is registered
3. Go to **System Settings → Privacy & Security → Extensions → Quick Look**
4. Enable **MdfyQuickLook**

## Usage

1. Open Finder
2. Navigate to any folder with `.md` files
3. Select a file
4. Press **Space**

You'll see:
- Rendered Markdown with proper typography
- Syntax-highlighted code blocks
- Tables with alignment
- KaTeX math equations
- Dark and light theme (follows system preference)
- "Open on mdfy.cc" button to publish

## Supported File Types

| Extension | Recognized |
|-----------|-----------|
| `.md` | Yes |
| `.markdown` | Yes |
| `.mdown` | Yes |
| `.mkd` | Yes |
| `.mkdn` | Yes |

## Tips

- Works in **Finder**, **Desktop**, and **Open/Save dialogs**
- Preview updates if you modify the file and press Space again
- Click **"Open on mdfy.cc"** to publish directly from the preview
- The preview respects your system dark/light mode setting

## Key takeaways
- QuickLook renders markdown files in Finder by pressing Space, powered by the mdfy.cc rendering engine.
- Installation requires installing the mdfy Mac app from mdfy.cc/plugins, then enabling MdfyQuickLook in System Settings Privacy and Security Extensions.
- The preview supports rendered markdown with typography, syntax-highlighted code blocks, tables with alignment, KaTeX math equations, and both dark and light themes.
