## ⚡ Quick Download & Install

No terminal or programming tools required. Simply download the pre-built installer for your platform:

### First-Time Launch Instructions

* **macOS (Gatekeeper bypass):**
  * Drag `ND Image Converter` into your `/Applications` folder.
  * If macOS says *"The application can't be opened"*, open **Terminal** and run:
    ```bash
    sudo xattr -cr "/Applications/ND Image Converter.app"
    ```
  * *Alternative:* Right-click the app in Finder $\rightarrow$ select **Open** $\rightarrow$ click **Open Anyway**.
* **Windows (SmartScreen warning):**
  * When *"Windows protected your PC"* appears, click **More info** $\rightarrow$ **Run anyway** (this appears only because open-source projects lack paid $400/yr certificate signatures).

## 👨‍💻 Development & Building from Source

If you want to contribute or build the application from source code:

### Prerequisites

* [Node.js](https://nodejs.org/) (v18.0 or newer)
* [Rust & Cargo](https://rustup.rs/) (stable toolchain)
* **macOS:** Xcode Command Line Tools (`xcode-select --install`)
* **Windows:** Visual Studio C++ Build Tools (with *Desktop development with C++*)

### Local Setup

### 1. Clone repository
```
git clone [https://github.com/duongtruongdp/ND-ImgConverter.git](https://github.com/duongtruongdp/ND-ImgConverter.git)
cd ND-ImgConverter
```

### 2. Install dependencies
```
npm install
```

### 3. Start development environment
```
npm run tauri dev
```

### 4. Packaging production release
```
npm run tauri build
```
The output installation files will be generated in:
- macOS: src-tauri/target/release/bundle/dmg/
- Windows: src-tauri/target/release/bundle/nsis/

## 🛠️ Troubleshooting

### Q&A

**Question**: Why does macOS say "The application can't be opened"?
macOS Gatekeeper may block apps downloaded from the internet. Try these fixes:

- Method 1 (Recommended): Open Terminal and run
```
xattr -cr /Applications/ND Image Converter.app
```
- Method 2: Right-click the app -> select "Open" -> click "Open" in the dialog.

- Method 3: Go to System Settings -> Privacy & Security -> scroll down and click "Open Anyway".

**Question**: Why does Windows show "Windows protected your PC"?
This SmartScreen warning appears because ND Image Converter isn't code-signed yet. Code signing certificates cost $400+/year, which isn't feasible for a free project at this stage.

To install safely:

- Click "More info" on the warning dialog
- Click "Run anyway"
ND Image Converter is 100% free with premium features — download from GitHub and verify it runs completely offline.
