+
+## Project Overview
+
+This project is a cross-platform Markdown editor and converter named **PanConverter**. It is built using the Electron framework, allowing it to run on Windows, macOS, and Linux. The application provides a rich text editor for writing Markdown, a live preview pane, and robust export capabilities powered by Pandoc.
+
+The core technologies used are:
+- **Electron:** For creating the desktop application.
+- **JavaScript:** The primary programming language.
+- **Pandoc:** For converting Markdown to various formats like PDF, DOCX, HTML, etc.
+- **Marked:** For parsing and rendering the Markdown preview in real-time.
+- **CodeMirror:** As the underlying text editor component.
+- **highlight.js:** For syntax highlighting in the editor.
+- **DOMPurify:** To sanitize the HTML output in the preview pane for security.
+
+The application features a tabbed interface for working with multiple files, various themes, find and replace functionality, and detailed document statistics.
+
+## Building and Running
+
+To build and run this project locally, you will need to have Node.js and npm installed.
+
+### Installation
+
+1.  **Clone the repository:**
+    ```bash
+    git clone https://github.com/amitwh/pan-converter.git
+    cd pan-converter
+    ```
+
+2.  **Install dependencies:**
+    ```bash
+    npm install
+    ```
+
+### Running the Application
+
+To run the application in development mode, use the following command:
+
+```bash
+npm start
+```
+
+### Building the Application
+
+You can build the application for different platforms using the scripts defined in `package.json`.
+
+-   **Build for the current platform:**
+    ```bash
+    npm run build
+    ```
+
+-   **Build for a specific platform:**
+    ```bash
+    npm run build:win    # For Windows
+    npm run build:mac    # For macOS
+    npm run build:linux  # For Linux
+    ```
+
+-   **Build for all platforms at once:**
+    ```bash
+    npm run dist:all
+    ```
+
+The distributable files will be located in the `dist/` directory.
+
+### Testing
+
+The project does not have a dedicated test suite configured. The `test` script in `package.json` currently returns an error.
+
+```bash
+npm test
+```
+
+## Development Conventions
+
+-   **Code Style:** The codebase is written in JavaScript (ES6+). There is no linter or formatter configured, but the code generally follows standard JavaScript conventions.
+-   **Main vs. Renderer Process:** The application logic is split between the Electron main process (`src/main.js`) and the renderer process (`src/renderer.js`).
+    -   `src/main.js` handles window management, application menus, file system operations, and communication with the operating system.
+    -   `src/renderer.js` manages the user interface, editor functionality, and the Markdown preview.
+-   **Dependencies:** Project dependencies are managed through `package.json`. `devDependencies` are used for the build process, while `dependencies` are required for the application to run.
+-   **User Data:** The application stores settings and recent files in the user's application data directory.
+-   **Pandoc Integration:** The application relies on a system-installed version of Pandoc for its export functionality. It does not bundle Pandoc.
