 ## Feature Implementation Guide

-### v1.5.0 Enhanced Features & Open Source Compatibility (Latest)
+### v1.9.1 ASCII Art & Code Block Preservation (Latest)
+
+#### 🎨 Preserved ASCII Art in Exports
+**ASCII Art, Charts, Tables & Flowcharts Now Export Exactly as Previewed** (`src/wordTemplateExporter.js`, `src/main.js`)
+
+**Problem Solved:**
+- Previously, ASCII art, flowcharts, and code blocks were being corrupted during export to Word and PDF
+- Line breaks, spacing, and monospace alignment were lost
+- Box-drawing characters and diagrams became unreadable
+
+**Solution Implemented:**
+1. **Enhanced Word Template Exporter** (`src/wordTemplateExporter.js:259-289`)
+   - Code blocks now render each line as a separate paragraph with exact spacing
+   - `white-space: pre` and `word-wrap: normal` prevent text wrapping
+   - Monospace font (Consolas) with consistent 18pt size
+   - Light gray background (#F5F5F5) for visual distinction
+   - `<w:keepLines/>` and `<w:wordWrap w:val="0"/>` preserve exact formatting
+
+2. **Improved ASCII Art Detection** (`src/wordTemplateExporter.js:410-456`)
+   - Extended Unicode box-drawing character support (╭╮╯╰ rounded corners, heavy box characters)
+   - Additional arrow characters (↔↕⇒⇐⇓⇑)
+   - More ASCII patterns detected (+---+---+, <---->, etc.)
+   - Better markdown table vs ASCII art differentiation
+
+3. **Enhanced PDF Export** (`src/main.js:1266-1268`, `src/main.js:1345-1347`, `src/main.js:2410-2412`)
+   - Added `-V monofont="Consolas"` for monospace code blocks
+   - Added `--highlight-style=tango` for syntax highlighting
+   - Applied to main export, fallback export, and CLI conversion
+
+4. **Electron PDF Fallback** (`src/main.js:1613-1637`)
+   - Enhanced CSS for `<pre>` and `<code>` elements
+   - `white-space: pre` prevents wrapping
+   - `font-family: Consolas, Monaco, 'Courier New', monospace`
+   - Print media query preserves formatting when printing
+
+5. **HTML Export** (`src/main.js:1525-1548`)
+   - Same CSS improvements as Electron PDF
+   - Code blocks maintain exact preview appearance
+
+**Key CSS Properties for ASCII Preservation:**
+```css
+pre {
+    white-space: pre;
+    word-wrap: normal;
+    font-family: Consolas, Monaco, 'Courier New', monospace;
+    font-size: 12px;
+    line-height: 1.4;
+}
+pre code {
+    white-space: pre;
+    word-wrap: normal;
+    display: block;
+}
+```
+
+**Word XML Properties for ASCII Preservation:**
+```xml
+<w:pPr>
+    <w:spacing w:line="240" w:lineRule="exact"/>
+    <w:keepLines/>
+    <w:wordWrap w:val="0"/>
+</w:pPr>
+<w:rPr>
+    <w:rFonts w:ascii="Consolas" w:hAnsi="Consolas" w:cs="Consolas"/>
+    <w:noProof/>
+</w:rPr>
+```
+

+
+### v1.9.0 Custom Headers & Footers
+
+#### 📄 Comprehensive Header & Footer System
+**Custom Headers & Footers for Standard Exports** (`src/main.js:701-853`, `src/index.html:929-1042`, `src/renderer.js:2560-2747`, `src/styles.css:3162-3432`)
+- **New Menu Option**: File → "Header & Footer Settings..." to configure headers/footers
+- **Three-Column Layout**: Left, Center, and Right positioning for both headers and footers
+- **Dynamic Field Support**: $PAGE$, $TOTAL$, $DATE$, $TIME$, $TITLE$, $AUTHOR$, $FILENAME$
+- **Logo/Image Embedding**: Upload logos to display in headers and footers
+- **Enable/Disable Toggle**: Quick on/off switch for all headers/footers
+- **Persistent Settings**: Configurations saved across sessions
+
+**Format Support:**
+- **PDF Export** (Standard): LaTeX-based headers/footers using fancyhdr package with automatic page numbering
+- **DOCX Export** (Standard): Word XML manipulation with field support for PAGE and NUMPAGES
+- **ODT Export**: OpenDocument format support (similar to DOCX implementation)
+- **PowerPoint (PPTX)**: Footer text with dynamic fields on slides
+- **Batch Converter**: Full header/footer support for all batch conversions
+
+**Dynamic Fields Processing:**
+- `$PAGE$` → Current page number (LaTeX: \thepage, Word: PAGE field)
+- `$TOTAL$` → Total pages (LaTeX: \pageref{LastPage}, Word: NUMPAGES field)
+- `$DATE$` → Current date (processed at export time)
+- `$TIME$` → Current time (processed at export time)
+- `$TITLE$` → Document title (from metadata or filename)
+- `$AUTHOR$` → Document author (from metadata)
+- `$FILENAME$` → File name without extension
+
+**Technical Implementation:**
+```javascript
+// processDynamicFields function in main.js
+function processDynamicFields(text, metadata = {}) {
+  const now = new Date();
+  result = text.replace(/\$DATE\$/g, now.toLocaleDateString());
+  result = result.replace(/\$TIME\$/g, now.toLocaleTimeString());
+  result = result.replace(/\$TITLE\$/g, metadata.title || 'Untitled');
+  // ... other replacements
+  return result;
+}
+
+// LaTeX header generation for PDF exports
+const latexHeader = `
+\\usepackage{fancyhdr}
+\\pagestyle{fancy}
+\\fancyhf{}
+\\lhead{${headerLeft}}
+\\chead{${headerCenter}}
+\\rhead{${headerRight}}
+\\lfoot{${footerLeft}}
+\\cfoot{${footerCenter}} // with \\thepage for page numbers
+\\rfoot{${footerRight}}
+`;
+
+// Word XML generation for DOCX exports
+const footerXml = `<?xml version="1.0"?>
+<w:ftr xmlns:w="http://schemas.openxmlformats.org/wordprocessingml/2006/main">
+  <w:p><w:r><w:t>${footerLeft}</w:t></w:r></w:p>
+  <w:p>
+    <w:fldSimple w:instr="PAGE"/> // Page number field
+    <w:r><w:t> of </w:t></w:r>
+    <w:fldSimple w:instr="NUMPAGES"/> // Total pages field
+  </w:p>
+  <w:p><w:r><w:t>${footerRight}</w:t></w:r></w:p>
+</w:ftr>`;
+```
+
+**Dialog Features:**
+- **Field Insertion Buttons**: Quick-insert dynamic fields via popup dialog
+- **Logo Upload**: Browse and select images for headers/footers
+- **Logo Preview**: Show selected logo filename
+- **Clear Buttons**: Remove uploaded logos
+- **Enable Toggle**: Disable headers/footers without losing settings
+- **Responsive Layout**: Grid-based three-column design
+- **Dark Theme Support**: Complete styling for all 22 themes
+
+**Integration Points:**
+- `buildPandocCommand()` - Adds LaTeX headers for PDF exports
+- `exportWithPandoc()` - Post-processes DOCX with header/footer XML
+- `performBatchConversion()` - Batch support for all formats
+- `addHeaderFooterToDocx()` - DOCX XML manipulation using PizZip
+
+**Dependencies:**
+- **PizZip** (v3.2.0) - ZIP file manipulation for DOCX/ODT
+- **fancyhdr** (LaTeX package) - Advanced headers/footers for PDF
+- **lastpage** (LaTeX package) - Total page count support
+
+**Key Improvements in v1.9.0:**
+1. ✅ Professional headers/footers for all standard export formats
+2. ✅ Dynamic field support with automatic value replacement
+3. ✅ Logo/image embedding in document headers/footers
+4. ✅ Batch converter integration with full header/footer support
+5. ✅ Persistent settings across application sessions
+6. ✅ User-friendly dialog with field insertion helper
+7. ✅ Complete dark theme support
+
+**Note**: Enhanced exports (DOCX Enhanced, PDF Enhanced) use Word templates which already have their own headers/footers defined in the template itself, so this feature specifically targets standard (non-templated) exports.
+
+---
+
+### v1.7.9 Enhanced Word Export with Template Support
+
+#### 📝 Template-Based Word Document Generation
+**Added Enhanced DOCX Export** (`src/wordTemplateExporter.js`, `src/main.js:540-596`, `src/main.js:242`)
+- **New Export Option**: "DOCX (Enhanced)" in File → Export menu with keyboard shortcut `Ctrl+Shift+W`
+- **Template Support**: Use custom Word templates to preserve branding, styles, and formatting
+- **Template Selection**: File → "Select Word Template..." menu option to choose custom templates
+- **Persistent Template**: Selected template is saved and reused across sessions
+- **Word XML Manipulation**: Direct manipulation of Word document XML using PizZip
+- **Template Page Preservation**: Preserves first 2 pages (cover + TOC) when using templates
+- **Smart Content Insertion**: Inserts markdown content after 2nd section break
+
+**Full Markdown Support:**
+- Headings (H1-H6) with markdown numbering stripped (e.g., "1.1 Title" → "Title")
+- Text formatting (bold, italic, bold+italic, strikethrough)
+- Inline code with Consolas font and gray background
+- Code blocks with monospace font and light gray background
+- Ordered and unordered lists (uses template numbering, strips markdown numbering)
+- Blockquotes with indentation
+- **Tables with orange header styling**:
+  - Orange header row (#F58220) with white bold text
+  - White data rows (no alternating colors)
+  - Orange borders (#F58220) on all cells
+  - Proper column alignment and spacing
+- Horizontal rules
+- Links
+- **ASCII Art and Flowcharts**:
+  - Detects box-drawing characters (┌, ─, │, └, etc.)
+  - Detects flowchart patterns with square brackets
+  - Preserves monospace alignment with Consolas font
+  - Each line rendered separately to prevent wrapping
+  - No-wrap paragraph properties for exact spacing
+  - **Red-colored arrows** (↓, →, ←, ↑) for enhanced visibility
+  - Gray background (#F5F5F5) for distinction from regular text
+
+**ASCII Art Detection Patterns:**
+- Unicode box-drawing characters: ┌┐└┘├┤┬┴┼─│═║╔╗╚╝╠╣╦╩╬
+- Arrow characters: ↓→←↑▼►◄▲
+- ASCII box patterns: +-----+, |-----|, [Text in brackets]
+- Flowchart steps: START, [Step Description], END
+
+**ASCII Art Rendering Features:**
+```javascript
+// Each line gets its own paragraph with no-wrap
+xml += `<w:p>
+    <w:pPr>
+        <w:wordWrap w:val="0"/>          // Disable wrapping
+        <w:keepLines/>                    // Keep lines together
+        <w:line="240" w:lineRule="exact"/>  // Exact line height
+    </w:pPr>
+    // Arrows colored red (#FF0000)
+    // Text in Consolas 16pt with gray background
+</w:p>`;
+```
+
+**Template Selection Workflow:**
+1. User clicks File → "Select Word Template..."
+2. Dialog opens to browse for .docx files
+3. Selected template path stored in global variable and persisted
+4. Template automatically loaded on app startup
+5. Enhanced export uses selected template (or defaults to `word_template.docx`)
+
+**Technical Implementation:**
+```javascript
+// Template selection function
+async function selectWordTemplate() {
+    const result = await dialog.showOpenDialog(mainWindow, {
+        title: 'Select Word Template',
+        filters: [{ name: 'Word Document', extensions: ['docx'] }],
+        properties: ['openFile']
+    });
+
+    if (!result.canceled && result.filePaths.length > 0) {
+        wordTemplatePath = result.filePaths[0];
+        store.set('wordTemplatePath', wordTemplatePath);
+    }
+}
+
+// Word Template Exporter with template support
+class WordTemplateExporter {
+    constructor(templatePath) {
+        this.templatePath = templatePath || path.join(__dirname, '../word_template.docx');
+    }
+
+    async convert(markdownContent, outputPath) {
+        // Load template as ZIP
+        const templateBuffer = fs.readFileSync(this.templatePath);
+        const zip = new PizZip(templateBuffer);
+
+        // Extract and modify document.xml
+        const documentXml = zip.file('word/document.xml').asText();
+        const newContentXml = this.markdownToWordXml(markdownContent);
+        const modifiedXml = this.insertContentAfterPage2(documentXml, newContentXml);
+
+        // Save modified document
+        zip.file('word/document.xml', modifiedXml);
+        const newDocBuffer = zip.generate({ type: 'nodebuffer' });
+        fs.writeFileSync(outputPath, newDocBuffer);
+    }
+}
+```
+
+**Menu Integration:**
+- Export: File → Export → "DOCX (Enhanced)" (`Ctrl+Shift+W`)
+- Template Selection: File → "Select Word Template..."
+- Template path saved to: `userData/settings.json`
+
+**Dependencies Added:**
+```json
+{
+  "docx": "^9.5.1",
+  "pizzip": "^3.2.0",
+  "docx4js": "^3.3.0"
+}
+```
+
+**Key Improvements in v1.7.9:**
+1. ✅ Template-based export preserving corporate branding
+2. ✅ Persistent template selection across sessions
+3. ✅ Tables with professional orange header styling and white data rows
+4. ✅ ASCII art and flowcharts with perfect alignment and no wrapping
+5. ✅ Red-colored arrows in flowcharts for enhanced readability
+6. ✅ Markdown numbering stripped from headings and lists
+7. ✅ Template's automatic numbering system used instead
+
+### v1.7.8 Critical Bug Fixes
+
+#### 🐛 File Association Fix for Packaged Apps
+**Fixed Command-Line Argument Parsing** (`src/main.js:1598-1627`, `src/main.js:70-90`)
+- **Root Cause**: `process.argv.slice(2)` works in development but fails in packaged apps
+- **Solution**: Detect if app is packaged using `app.isPackaged` and use correct slice index
+  - Development: `process.argv.slice(2)` - ['electron', 'app.js', 'file.md']
+  - Packaged: `process.argv.slice(1)` - ['PanConverter.exe', 'file.md']
+- **Path Resolution**: Added proper path resolution for both absolute and relative paths
+- **Comprehensive Logging**: Added detailed console logs to debug file loading issues
+- **Second Instance Handler**: Also fixed second-instance handler to use same logic
+
+**Technical Implementation:**
+```javascript
+// Detect packaged vs development mode
+const startIndex = app.isPackaged ? 1 : 2;
+const fileArgs = process.argv.slice(startIndex);
+
+// Resolve paths properly
+for (const arg of fileArgs) {
+  if ((arg.endsWith('.md') || arg.endsWith('.markdown'))) {
+    const resolvedPath = path.isAbsolute(arg) ? arg : path.resolve(process.cwd(), arg);
+    if (fs.existsSync(resolvedPath)) {
+      app.pendingFile = resolvedPath;
+      break;
+    }
+  }
+}
+```
+
+**Fixed Issues:**
+- ✅ Files now open correctly on first double-click in packaged app
+- ✅ Command-line arguments properly parsed in both dev and production
+- ✅ Relative and absolute paths handled correctly
+- ✅ Comprehensive logging for debugging file association issues
+
+#### 🖨️ Print Preview Fix
+**Fixed Print Output to Show Preview Content** (`src/renderer.js:1178-1204`, `src/styles.css:2828-3014`)
+- **Root Cause**: Manual DOM manipulation conflicted with CSS `@media print` rules
+- **Solution**: Simplified handler to rely on CSS `@media print` for hiding UI elements
+- **CSS Enhancements**:
+  - Added selectors for dynamic preview panes `[id^="preview-pane-"]` and `[id^="editor-pane-"]`
+  - Added `.tab-content` to ensure full-width rendering
+  - Added body class-based styling for no-styles mode
+- **Removed Manual Hiding**: Eliminated manual `display: none` manipulation in favor of CSS
+
+**Technical Implementation:**
+```javascript
+// Simplified print handler - let CSS do the work
+function handlePrintPreview(withStyles) {
+  const activeTabId = tabManager ? tabManager.activeTabId : 1;
+  const previewContent = document.getElementById(`preview-${activeTabId}`);
+
+  if (!previewContent || !previewContent.innerHTML.trim()) {
+    alert('Nothing to print...');
+    return;
+  }
+
+  // Add body classes for CSS styling
+  if (!withStyles) {
+    document.body.classList.add('printing-no-styles');
+  }
+  document.body.classList.add('printing');
+
+  setTimeout(() => {
+    ipcRenderer.send('do-print', { withStyles });
+    setTimeout(() => {
+      document.body.classList.remove('printing', 'printing-no-styles');
+    }, 1000);
+  }, 100);
+}
+```
+
+**CSS Updates:**
+```css
+@media print {
+  /* Hide all UI elements */
+  #toolbar, #tab-bar, .editor-pane, [id^="editor-pane-"] {
+    display: none !important;
+  }
+
+  /* Show preview in full width */
+  [id^="preview-"], [id^="preview-pane-"], .tab-content {
+    display: block !important;
+    width: 100% !important;
+    padding: 20px !important;
+  }
+}
+```
+
+**Fixed Issues:**
+- ✅ Print now correctly renders preview content, not toolbar
+- ✅ Both print modes work (with styles and without styles)
+- ✅ Clean, professional print output with proper formatting
+- ✅ Proper page breaks, typography, and layout optimization
+
+#### 🔧 Development Cleanup

+
+### v1.7.7 Print & Enhanced PDF Support
+
+#### 🖨️ Native Print Functionality
+**Added Print Submenu to File Menu** (`src/main.js:202-215`, `src/renderer.js:1152-1188`, `src/styles.css:2828-2994`)
+- **Print Menu**: Submenu in File menu with two print options
+  - **Print Preview** (`Ctrl+P`) - Prints preview in black text, no background colors (ink-saving)
+  - **Print Preview (With Styles)** - Prints with full theme colors and styling
+- **Preview-Only Printing**: Only renders the markdown preview, hides all editor UI
+- **Native Print Dialog**: Uses Electron's webContents.print() for native OS print dialogs
+- **Professional Output**: Automatically hides editor, toolbar, tabs, and status bar during print
+- **Print Optimization**: Smart page breaks, proper formatting for headings, code blocks, tables
+- **Cross-Platform**: Works on Windows, macOS, and Linux with native printer support
+
+**Print Options:**
+1. **Print Preview** (Ctrl+P)
+   - Black text on white background for professional printing
+   - No background colors to save ink
+   - Perfect for documents and reports
+   - Minimal ink consumption
+
+2. **Print Preview (With Styles)**
+   - Full theme colors and styling
+   - Preserves markdown formatting with visual hierarchy
+   - Better for design-focused documents
+   - Shows code blocks with colored syntax highlighting
+
+**Technical Implementation:**
+```javascript
+// Main process - two print handlers
+ipcMain.on('print-preview', (event) => {
+  mainWindow.webContents.send('prepare-print-preview', false);
+  setTimeout(() => {
+    mainWindow.webContents.print({
+      silent: false,
+      printBackground: false,
+      color: true,
+      margin: { marginType: 'default' }
+    });
+  }, 100);
+});
+
+ipcMain.on('print-preview-styled', (event) => {
+  mainWindow.webContents.send('prepare-print-preview', true);
+  setTimeout(() => {
+    mainWindow.webContents.print({
+      silent: false,
+      printBackground: true,
+      color: true,
+      margin: { marginType: 'default' }
+    });
+  }, 100);
+});
+
+// Renderer process - prepares preview for printing
+ipcRenderer.on('prepare-print-preview', (event, withStyles) => {
+  // Hide editor and UI elements
+  document.getElementById('editor-container').style.display = 'none';
+  document.getElementById('toolbar').style.display = 'none';
+  document.getElementById('tab-bar').style.display = 'none';
+  document.getElementById('status-bar').style.display = 'none';
+
+  // Add print mode classes
+  const preview = document.getElementById('preview');
+  preview.classList.add('print-mode');
+  if (!withStyles) {
+    preview.classList.add('print-no-styles');
+  }
+
+  // Restore UI after print
+  setTimeout(() => {
+    document.getElementById('editor-container').style.display = '';
+    document.getElementById('toolbar').style.display = '';
+    document.getElementById('tab-bar').style.display = '';
+    document.getElementById('status-bar').style.display = '';
+    preview.classList.remove('print-mode', 'print-no-styles');
+  }, 500);
+});
+```
+
+**CSS Print Styles** (`src/styles.css:2828-2994`)
+- Comprehensive @media print stylesheet
+- Hides all UI elements in print view
+- Optimizes preview for paper output
+- Smart page breaks for headings and tables
+- Proper formatting for code blocks, lists, tables
+- Image optimization and link handling
+- Professional typography with 12pt font size
+
+#### 📦 Enhanced PDF Export Dependencies
+**Added Native PDF Generation Libraries** (package.json)
+- **PDFKit** (v0.14.0) - Native PDF generation without Pandoc dependency
+- **html2pdf.js** (v0.10.1) - HTML to PDF conversion for rich formatted output
+- **Benefits**: PDF exports now work even without system Pandoc installation
+- **Future Enhancement**: Enables PDF generation with embedded fonts and graphics
+- **Offline Support**: Complete PDF generation offline without external services
+
+**Updated Dependencies:**
+```json
+{
+  "pdfkit": "^0.14.0",
+  "html2pdf.js": "^0.10.1"
+}
+```
+
+**Features Enabled:**
+- PDF export works independently of Pandoc installation
+- Higher quality PDF output with better formatting control
+- Support for custom fonts, images, and complex layouts
+- Faster PDF generation times
+- Reduced system dependencies for better portability
+
+#### 🔧 Keyboard Shortcut Updates
+**Remapped Shortcuts** (`src/main.js`)
+- **Print**: `Ctrl+P` (new in v1.7.7) - Opens native print dialog
+- **Toggle Preview**: Changed from `Ctrl+P` to `Ctrl+Shift+P` to avoid conflicts
+- **Backward Compatibility**: No breaking changes to existing workflows
+
+### v1.7.6 UI Improvement
+
+#### 🎨 Table Header Styling Cleanup
+**Removed Custom Background Colors** (`src/styles.css:327-329`, `src/styles.css:451-453`)
+- Removed gray background color (#f6f8fa) from table headers in default theme
+- Removed dark theme table header background styling block entirely
+- Table headers now blend naturally with preview background for cleaner appearance
+- Headers maintain font-weight: 600 for visual distinction
+- All other table styling preserved (borders, alternating row colors)
+
+**User Feedback Implementation:**
+- Based on user feedback: "remove the theming of table headers, it looks bad"
+- Result: Professional, clean table presentation matching overall preview styling
+- Consistent with normal preview theming across all themes
+
+### v1.7.5 Critical File Association Fix
+
+#### 🐛 Single-Instance Lock for Windows File Association
+**Fixed Installed App Double-Click Behavior** (`src/main.js:52-85`)
+- **Root Cause**: Windows launches second instance when double-clicking files with app already running
+- **Solution**: Implemented `app.requestSingleInstanceLock()` pattern
+- **Second Instance Handler**: Captures file path from new instance attempts and opens in existing instance
+- **Focus Management**: Automatically focuses and restores existing window
+- **Renderer Readiness**: Proper handling of file queue with `rendererReady` state
+
+**Technical Implementation:**
+```javascript
+const gotTheLock = app.requestSingleInstanceLock();
+if (!gotTheLock) {
+  app.quit();
+} else {
+  app.on('second-instance', (event, commandLine, workingDirectory) => {
+    // Focus existing window
+    if (mainWindow) {
+      if (mainWindow.isMinimized()) mainWindow.restore();
+      mainWindow.focus();
+    }
+    // Extract and open file from second instance
+    const fileArgs = commandLine.slice(2);
+    for (const arg of fileArgs) {
+      if ((arg.endsWith('.md') || arg.endsWith('.markdown')) && fs.existsSync(arg)) {
+        if (rendererReady) {
+          openFileFromPath(arg);
+        } else {
+          app.pendingFile = arg;
+        }
+        break;
+      }
+    }
+  });
+}
+```
+
+**Fixed Issues:**
+- ✅ Double-click `.md` files in Windows Explorer now opens correctly
+- ✅ Right-click "Open with PanConverter" now works in installed app
+- ✅ File association behavior now consistent between development and production
+- ✅ Single instance maintained across all file opening methods
+
+**Why Previous Attempts Failed:**
+- v1.7.3-1.7.4: Only added `rendererReady` checks but missed second-instance handling
+- Development testing passed but production failed (different execution paths)
+- Second instance would start, receive file, then exit without passing to first instance
+
+### v1.7.2 Enhanced Themes & Bug Fixes

+# GEMINI.md
+
+## 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.

+# PanConverter Windows Explorer Context Menu Integration
+
+This directory contains scripts to add PanConverter to the Windows Explorer context menu, allowing you to right-click on files and convert them directly without opening the full application.
+
+## Features
+
+### Context Menu Options
+- **Convert with PanConverter**: Shows a format selection dialog for any supported file
+- **PanConverter > Convert to...**: Direct conversion options (for Markdown files)
+  - PDF
+  - HTML  
+  - DOCX
+  - LaTeX
+  - PowerPoint
+
+### Supported File Types
+- **Markdown**: `.md`, `.markdown`
+- **HTML**: `.html`, `.htm`
+- **Documents**: `.docx`, `.odt`, `.rtf`
+- **LaTeX**: `.tex`
+- **PDF**: `.pdf`
+- **Presentations**: `.pptx`, `.ppt`, `.odp`
+
+## Installation Methods
+
+### Method 1: Automatic (During PanConverter Installation)
+When installing PanConverter using the Windows installer, you'll be prompted to install context menu integration automatically.
+
+### Method 2: Manual Installation
+
+#### Using PowerShell (Recommended)
+1. Right-click on `install-context-menu.ps1`
+2. Select "Run with PowerShell"
+3. Follow the prompts (will request administrator privileges)
+
+#### Using Batch File
+1. Right-click on `install-context-menu.bat`
+2. Select "Run as administrator"
+3. Follow the prompts
+
+#### Using Registry File Directly
+1. Right-click on `install-context-menu.reg`
+2. Select "Merge" 
+3. Confirm the registry modification
+
+## Uninstallation
+
+### Using PowerShell
+```powershell
+.\install-context-menu.ps1 -Uninstall
+```
+
+### Using Batch File
+Run `uninstall-context-menu.bat` as administrator
+
+### Using Registry File
+Run `uninstall-context-menu.reg`
+
+## How It Works
+
+### Command Line Interface
+The context menu integration works by passing command line arguments to PanConverter:
+
+- `--convert <file>`: Shows conversion dialog for the specified file
+- `--convert-to <format> <file>`: Directly converts to the specified format
+
+### Examples
+```batch
+# Show conversion dialog
+PanConverter.exe --convert "document.md"
+
+# Direct conversion to PDF
+PanConverter.exe --convert-to pdf "document.md"
+```
+
+### Conversion Process
+1. PanConverter reads the input file
+2. Creates a temporary file if needed
+3. Uses Pandoc to convert to the target format
+4. Saves the output in the same directory as the input file
+5. Shows a Windows notification when complete
+
+## Requirements
+
+- PanConverter must be installed in the default location: `%LOCALAPPDATA%\Programs\PanConverter\`
+- Pandoc must be installed and accessible from the command line
+- Administrator privileges required for registry modifications
+
+## Troubleshooting
+
+### Context Menu Not Appearing
+1. Ensure you ran the installation script as administrator
+2. Try logging out and back in, or restart Windows Explorer
+3. Check if PanConverter is installed in the expected location
+
+### Conversion Failures
+1. Verify Pandoc is installed: `pandoc --version`
+2. Check if the input file is not corrupted or locked
+3. Ensure you have write permissions in the output directory
+
+### Permission Errors
+- The installation scripts require administrator privileges to modify the registry
+- If you get permission errors, right-click and "Run as administrator"
+
+## File Descriptions
+
+- `install-context-menu.reg`: Registry entries for context menu
+- `uninstall-context-menu.reg`: Registry entries removal
+- `install-context-menu.ps1`: PowerShell installation script
+- `install-context-menu.bat`: Batch installation script  
+- `uninstall-context-menu.bat`: Batch uninstallation script
+- `nsis-installer.nsh`: NSIS installer integration script
+
+## Security Note
+
+The scripts modify the Windows registry to add context menu entries. Only run these scripts if you trust the source and understand the changes being made to your system.
