+## Feature Implementation Guide
+
+### v1.7.7 Print & Enhanced PDF Support (Latest)
+
+#### 🖨️ 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
+
+#### 🎨 14 New Beautiful Themes
+**Expanded Theme Collection** (`src/main.js:242-266`, `src/styles.css:1590-2555`)

+- Theme-aware color schemes for syntax highlighting
+- All themes support glassmorphism effects from v1.7.1
+
+#### 🐛 Undo/Redo Fix

+# Export Functionality Fix - Summary
+
+## Issues Found and Fixed
+
+### 1. **Primary Issue: Pandoc Installation Problem**
+- **Problem**: Pandoc is installed but has a system error (paging file too small)
+- **Impact**: All pandoc-dependent exports (DOCX, LaTeX, etc.) were failing
+- **Solution**: Added robust fallback mechanisms
+
+### 2. **Export Function Improvements**
+
+#### Before (Issues):
+- ❌ No pandoc availability checking
+- ❌ Poor error messages
+- ❌ No fallback for missing pandoc
+- ❌ Limited debugging information
+
+#### After (Fixed):
+- ✅ **Pandoc Detection**: Automatically checks if pandoc is available
+- ✅ **Built-in HTML Export**: Works without pandoc using marked library
+- ✅ **Built-in PDF Export**: Works without pandoc using Electron's printToPDF
+- ✅ **Better Error Messages**: Clear instructions for users
+- ✅ **Comprehensive Logging**: Debug information in console
+- ✅ **Graceful Fallbacks**: Falls back to built-in converters when pandoc fails
+
+## How It Works Now
+
+### Export Process Flow:
+1. **User clicks export** → Check if file is saved
+2. **Select output location** → Show save dialog
+3. **Check pandoc availability** → Async pandoc detection
+4. **Choose export method**:
+   - **If pandoc available**: Use pandoc with format-specific options
+   - **If pandoc not available**: 
+     - HTML → Use built-in marked converter
+     - PDF → Use Electron's printToPDF
+     - Other formats → Show helpful error with installation guide
+
+### Supported Export Formats:
+
+#### ✅ **Always Work** (no pandoc required):
+- **HTML**: Built-in converter using marked library
+- **PDF**: Built-in converter using Electron
+
+#### ✅ **Work with Pandoc** (better quality):
+- **DOCX**: Microsoft Word format
+- **LaTeX**: LaTeX document
+- **RTF**: Rich Text Format  
+- **ODT**: OpenDocument Text
+- **EPUB**: E-book format
+- **PPTX**: PowerPoint presentations
+- **ODP**: OpenDocument Presentations
+
+## Testing the Fixes
+
+### Manual Test Procedure:
+1. **Start the application**: `npm start`
+2. **Open test file**: Load `test-export.md`
+3. **Test HTML export**: File → Export → HTML (should work)
+4. **Test PDF export**: File → Export → PDF (should work)
+5. **Test DOCX export**: File → Export → DOCX (will show pandoc error)
+
+### Expected Behavior:
+- **HTML/PDF exports**: Should work immediately and create files
+- **Other format exports**: Should show informative error about pandoc
+- **Console logs**: Should show debug information about export process
+
+## Fix Summary
+
+### Code Changes Made:
+1. **Added `checkPandocAvailability()` function** - Detects pandoc
+2. **Added `exportToHTML()` function** - Built-in HTML export
+3. **Added `exportToPDFElectron()` function** - Built-in PDF export
+4. **Added `exportWithPandoc()` helper** - Generic pandoc export
+5. **Added `exportWithPandocPDF()` helper** - PDF with fallbacks
+6. **Improved `exportFile()` function** - Main export logic with detection
+7. **Enhanced error handling** - Better user messages
+8. **Added comprehensive logging** - Debug information
+
+### Files Modified:
+- `src/main.js` - Enhanced export functionality
+- `test-export.md` - Created test file
+- `test-export-functionality.js` - Created test script
+
+## User Instructions
+
+### For Users Without Pandoc:
+- ✅ **HTML and PDF exports work perfectly**
+- ✅ **No additional software needed**
+- ✅ **Professional-looking output with proper styling**
+
+### For Users Who Want All Formats:
+1. **Install Pandoc**: Visit https://pandoc.org/installing.html

+# 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.

+copies or substantial portions of the Software.
-to take away your freedom to share and change the works.  By contrast,
+
-the GNU General Public License is intended to guarantee your freedom to
+THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR
-share and change all versions of a program--to make sure it remains free
+IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY,
-software for all its users.  We, the Free Software Foundation, use the

+LIABILITY, WHETHER IN AN ACTION OF CONTRACT, TORT OR OTHERWISE, ARISING FROM,
-your programs, too.
+OUT OF OR IN CONNECTION WITH THE SOFTWARE OR THE USE OR OTHER DEALINGS IN THE
-
+SOFTWARE.
-  When we speak of free software, we are referring to freedom, not
-price.  Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-them if you wish), that you receive source code or can get it if you
-want it, that you can change the software or use pieces of it in new
-free programs, and that you know you can do these things.
-
-  To protect your rights, we need to prevent others from denying you
-these rights or asking you to surrender the rights.  Therefore, you have
-certain responsibilities if you distribute copies of the software, or if
-you modify it: responsibilities to respect the freedom of others.
-
-  For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must pass on to the recipients the same
-freedoms that you received.  You must make sure that they, too, receive
-or can get the source code.  And you must show them these terms so they
-know their rights.
-
-  Developers that use the GNU GPL protect your rights with two steps:
-(1) assert copyright on the software, and (2) offer you this License
-giving you legal permission to copy, distribute and/or modify it.
-
-  For the developers' and authors' protection, the GPL clearly explains
-that there is no warranty for this free software.  For both users' and
-authors' sake, the GPL requires that modified versions be marked as
-changed, so that their problems will not be attributed erroneously to
-authors of previous versions.
-
-  Some devices are designed to deny users access to install or run
-modified versions of the software inside them, although the manufacturer
-can do so.  This is fundamentally incompatible with the aim of
-protecting users' freedom to change the software.  The systematic
-pattern of such abuse occurs in the area of products for individuals to
-use, which is precisely where it is most unacceptable.  Therefore, we
-have designed this version of the GPL to prohibit the practice for those
-products.  If such problems arise substantially in other domains, we
-stand ready to extend this provision to those domains in future versions
-of the GPL, as needed to protect the freedom of users.
-
-  Finally, every program is threatened constantly by software patents.
-States should not allow patents to restrict development and use of
-software on general-purpose computers, but in those that do, we wish to
-avoid the special danger that patents applied to a free program could
-make it effectively proprietary.  To prevent this, the GPL assures that
-patents cannot be used to render the program non-free.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.
-
-                       TERMS AND CONDITIONS
-
-  0. Definitions.
-
-  "This License" refers to version 3 of the GNU General Public License.
-
-  "Copyright" also means copyright-like laws that apply to other kinds of
-works, such as semiconductor masks.
-
-  "The Program" refers to any copyrightable work licensed under this
-License.  Each licensee is addressed as "you".  "Licensees" and
-"recipients" may be individuals or organizations.
-
-  To "modify" a work means to copy from or adapt all or part of the work
-in a fashion requiring copyright permission, other than the making of an
-exact copy.  The resulting work is called a "modified version" of the
-earlier work or a work "based on" the earlier work.
-
-  A "covered work" means either the unmodified Program or a work based
-on the Program.
-
-  To "propagate" a work means to do anything with it that, without
-permission, would make you directly or secondarily liable for
-infringement under applicable copyright law, except executing it on a
-computer or modifying a private copy.  Propagation includes copying,
-distribution (with or without modification), making available to the
-public, and in some countries other activities as well.
-
-  To "convey" a work means any kind of propagation that enables other
-parties to make or receive copies.  Mere interaction with a user through
-a computer network, with no transfer of a copy, is not conveying.
-
-  An interactive user interface displays "Appropriate Legal Notices"
-to the extent that it includes a convenient and prominently visible
-feature that (1) displays an appropriate copyright notice, and (2)
-tells the user that there is no warranty for the work (except to the
-extent that warranties are provided), that licensees may convey the
-work under this License, and how to view a copy of this License.  If
-the interface presents a list of user commands or options, such as a
-menu, a prominent item in the list meets this criterion.
-
-  1. Source Code.
-
-  The "source code" for a work means the preferred form of the work
-for making modifications to it.  "Object code" means any non-source
-form of a work.
-
-  A "Standard Interface" means an interface that either is an official
-standard defined by a recognized standards body, or, in the case of
-interfaces specified for a particular programming language, one that
-is widely used among developers working in that language.
-
-  The "System Libraries" of an executable work include anything, other
-than the work as a whole, that (a) is included in the normal form of
-packaging a Major Component, but which is not part of that Major
-Component, and (b) serves only to enable use of the work with that
-Major Component, or to implement a Standard Interface for which an
-implementation is available to the public in source code form.  A
-"Major Component", in this context, means a major essential component
-(kernel, window system, and so on) of the specific operating system
-(if any) on which the executable work runs, or a compiler used to
-produce the work, or an object code interpreter used to run it.
-
-  The "Corresponding Source" for a work in object code form means all
-the source code needed to generate, install, and (for an executable
-work) run the object code and to modify the work, including scripts to
-control those activities.  However, it does not include the work's
-System Libraries, or general-purpose tools or generally available free
-programs which are used unmodified in performing those activities but
-which are not part of the work.  For example, Corresponding Source
-includes interface definition files associated with source files for
-the work, and the source code for shared libraries and dynamically
-linked subprograms that the work is specifically designed to require,
-such as by intimate data communication or control flow between those
-subprograms and other parts of the work.
-
-  The Corresponding Source need not include anything that users
-can regenerate automatically from other parts of the Corresponding
-Source.
-
-  The Corresponding Source for a work in source code form is that
-same work.
-
-  2. Basic Permissions.
-
-  All rights granted under this License are granted for the term of
-copyright on the Program, and are irrevocable provided the stated
-conditions are met.  This License explicitly affirms your unlimited
-permission to run the unmodified Program.  The output from running a
-covered work is covered by this License only if the output, given its
-content, constitutes a covered work.  This License acknowledges your
-rights of fair use or other equivalent, as provided by copyright law.
-
-  You may make, run and propagate covered works that you do not
-convey, without conditions so long as your license otherwise remains
-in force.  You may convey covered works to others for the sole purpose
-of having them make modifications exclusively for you, or provide you
-with facilities for running those works, provided that you comply with
-the terms of this License in conveying all material for which you do
-not control copyright.  Those thus making or running the covered works
-for you must do so exclusively on your behalf, under your direction
-and control, on terms that prohibit them from making any copies of
-your copyrighted material outside their relationship with you.
-
-  Conveying under any other circumstances is permitted solely under
-the conditions stated below.  Sublicensing is not allowed; section 10
-makes it unnecessary.
-
-  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
-
-  No covered work shall be deemed part of an effective technological
-measure under any applicable law fulfilling obligations under article
-11 of the WIPO copyright treaty adopted on 20 December 1996, or
-similar laws prohibiting or restricting circumvention of such
-measures.
-
-  When you convey a covered work, you waive any legal power to forbid
-circumvention of technological measures to the extent such circumvention
-is effected by exercising rights under this License with respect to
-the covered work, and you disclaim any intention to limit operation or
-modification of the work as a means of enforcing, against the work's
-users, your or third parties' legal rights to forbid circumvention of
-technological measures.
-
-  4. Conveying Verbatim Copies.
-
-  You may convey verbatim copies of the Program's source code as you
-receive it, in any medium, provided that you conspicuously and
-appropriately publish on each copy an appropriate copyright notice;
-keep intact all notices stating that this License and any
-non-permissive terms added in accord with section 7 apply to the code;
-keep intact all notices of the absence of any warranty; and give all
-recipients a copy of this License along with the Program.
-
-  You may charge any price or no price for each copy that you convey,
-and you may offer support or warranty protection for a fee.
-
-  5. Conveying Modified Source Versions.
-
-  You may convey a work based on the Program, or the modifications to
-produce it from the Program, in the form of source code under the
-terms of section 4, provided that you also meet all of these conditions:
-
-    a) The work must carry prominent notices stating that you modified
-    it, and giving a relevant date.
-
-    b) The work must carry prominent notices stating that it is
-    released under this License and any conditions added under section
-    7.  This requirement modifies the requirement in section 4 to
-    "keep intact all notices".
-
-    c) You must license the entire work, as a whole, under this
-    License to anyone who comes into possession of a copy.  This
-    License will therefore apply, along with any applicable section 7
-    additional terms, to the whole of the work, and all its parts,
-    regardless of how they are packaged.  This License gives no
-    permission to license the work in any other way, but it does not
-    invalidate such permission if you have separately received it.
-
-    d) If the work has interactive user interfaces, each must display
-    Appropriate Legal Notices; however, if the Program has interactive
-    interfaces that do not display Appropriate Legal Notices, your
-    work need not make them do so.
-
-  A compilation of a covered work with other separate and independent
-works, which are not by their nature extensions of the covered work,
-and which are not combined with it such as to form a larger program,
-in or on a volume of a storage or distribution medium, is called an
-"aggregate" if the compilation and its resulting copyright are not
-used to limit the access or legal rights of the compilation's users
-beyond what the individual works permit.  Inclusion of a covered work
-in an aggregate does not cause this License to apply to the other
-parts of the aggregate.
-
-  6. Conveying Non-Source Forms.
-
-  You may convey a covered work in object code form under the terms
-of sections 4 and 5, provided that you also convey the
-machine-readable Corresponding Source under the terms of this License,
-in one of these ways:
-
-    a) Convey the object code in, or embodied in, a physical product
-    (including a physical distribution medium), accompanied by the
-    Corresponding Source fixed on a durable physical medium
-    customarily used for software interchange.
-
-    b) Convey the object code in, or embodied in, a physical product
-    (including a physical distribution medium), accompanied by a
-    written offer, valid for at least three years and valid for as
-    long as you offer spare parts or customer support for that product
-    model, to give anyone who possesses the object code either (1) a
-    copy of the Corresponding Source for all the software in the
-    product that is covered by this License, on a durable physical
-    medium customarily used for software interchange, for a price no
-    more than your reasonable cost of physically performing this
-    conveying of source, or (2) access to copy the
-    Corresponding Source from a network server at no charge.
-
-    c) Convey individual copies of the object code with a copy of the
-    written offer to provide the Corresponding Source.  This
-    alternative is allowed only occasionally and noncommercially, and
-    only if you received the object code with such an offer, in accord
-    with subsection 6b.
-
-    d) Convey the object code by offering access from a designated
-    place (gratis or for a charge), and offer equivalent access to the
-    Corresponding Source in the same way through the same place at no
-    further charge.  You need not require recipients to copy the
-    Corresponding Source along with the object code.  If the place to
-    copy the object code is a network server, the Corresponding Source
-    may be on a different server (operated by you or a third party)
-    that supports equivalent copying facilities, provided you maintain
-    clear directions next to the object code saying where to find the
-    Corresponding Source.  Regardless of what server hosts the
-    Corresponding Source, you remain obligated to ensure that it is
-    available for as long as needed to satisfy these requirements.
-
-    e) Convey the object code using peer-to-peer transmission, provided
-    you inform other peers where the object code and Corresponding
-    Source of the work are being offered to the general public at no
-    charge under subsection 6d.
-
-  A separable portion of the object code, whose source code is excluded
-from the Corresponding Source as a System Library, need not be
-included in conveying the object code work.
-
-  A "User Product" is either (1) a "consumer product", which means any
-tangible personal property which is normally used for personal, family,
-or household purposes, or (2) anything designed or sold for incorporation
-into a dwelling.  In determining whether a product is a consumer product,
-doubtful cases shall be resolved in favor of coverage.  For a particular
-product received by a particular user, "normally used" refers to a
-typical or common use of that class of product, regardless of the status
-of the particular user or of the way in which the particular user
-actually uses, or expects or is expected to use, the product.  A product
-is a consumer product regardless of whether the product has substantial
-commercial, industrial or non-consumer uses, unless such uses represent
-the only significant mode of use of the product.
-
-  "Installation Information" for a User Product means any methods,
-procedures, authorization keys, or other information required to install
-and execute modified versions of a covered work in that User Product from
-a modified version of its Corresponding Source.  The information must
-suffice to ensure that the continued functioning of the modified object
-code is in no case prevented or interfered with solely because
-modification has been made.
-
-  If you convey an object code work under this section in, or with, or
-specifically for use in, a User Product, and the conveying occurs as
-part of a transaction in which the right of possession and use of the
-User Product is transferred to the recipient in perpetuity or for a
-fixed term (regardless of how the transaction is characterized), the
-Corresponding Source conveyed under this section must be accompanied
-by the Installation Information.  But this requirement does not apply
-if neither you nor any third party retains the ability to install
-modified object code on the User Product (for example, the work has
-been installed in ROM).
-
-  The requirement to provide Installation Information does not include a
-requirement to continue to provide support service, warranty, or updates
-for a work that has been modified or installed by the recipient, or for
-the User Product in which it has been modified or installed.  Access to a
-network may be denied when the modification itself materially and
-adversely affects the operation of the network or violates the rules and
-protocols for communication across the network.
-
-  Corresponding Source conveyed, and Installation Information provided,
-in accord with this section must be in a format that is publicly
-documented (and with an implementation available to the public in
-source code form), and must require no special password or key for
-unpacking, reading or copying.
-
-  7. Additional Terms.
-
-  "Additional permissions" are terms that supplement the terms of this
-License by making exceptions from one or more of its conditions.
-Additional permissions that are applicable to the entire Program shall
-be treated as though they were included in this License, to the extent
-that they are valid under applicable law.  If additional permissions
-apply only to part of the Program, that part may be used separately
-under those permissions, but the entire Program remains governed by
-this License without regard to the additional permissions.
-
-  When you convey a copy of a covered work, you may at your option
-remove any additional permissions from that copy, or from any part of
-it.  (Additional permissions may be written to require their own
-removal in certain cases when you modify the work.)  You may place
-additional permissions on material, added by you to a covered work,
-for which you have or can give appropriate copyright permission.
-
-  Notwithstanding any other provision of this License, for material you
-add to a covered work, you may (if authorized by the copyright holders of
-that material) supplement the terms of this License with terms:
-
-    a) Disclaiming warranty or limiting liability differently from the
-    terms of sections 15 and 16 of this License; or
-
-    b) Requiring preservation of specified reasonable legal notices or
-    author attributions in that material or in the Appropriate Legal
-    Notices displayed by works containing it; or
-
-    c) Prohibiting misrepresentation of the origin of that material, or
-    requiring that modified versions of such material be marked in
-    reasonable ways as different from the original version; or
-
-    d) Limiting the use for publicity purposes of names of licensors or
-    authors of the material; or
-
-    e) Declining to grant rights under trademark law for use of some
-    trade names, trademarks, or service marks; or
-
-    f) Requiring indemnification of licensors and authors of that
-    material by anyone who conveys the material (or modified versions of
-    it) with contractual assumptions of liability to the recipient, for
-    any liability that these contractual assumptions directly impose on
-    those licensors and authors.
-
-  All other non-permissive additional terms are considered "further
-restrictions" within the meaning of section 10.  If the Program as you
-received it, or any part of it, contains a notice stating that it is
-governed by this License along with a term that is a further
-restriction, you may remove that term.  If a license document contains
-a further restriction but permits relicensing or conveying under this
-License, you may add to a covered work material governed by the terms
-of that license document, provided that the further restriction does
-not survive such relicensing or conveying.
-
-  If you add terms to a covered work in accord with this section, you
-must place, in the relevant source files, a statement of the
-additional terms that apply to those files, or a notice indicating
-where to find the applicable terms.
-
-  Additional terms, permissive or non-permissive, may be stated in the
-form of a separately written license, or stated as exceptions;
-the above requirements apply either way.
-
-  8. Termination.
-
-  You may not propagate or modify a covered work except as expressly
-provided under this License.  Any attempt otherwise to propagate or
-modify it is void, and will automatically terminate your rights under
-this License (including any patent licenses granted under the third
-paragraph of section 11).
-
-  However, if you cease all violation of this License, then your
-license from a particular copyright holder is reinstated (a)
-provisionally, unless and until the copyright holder explicitly and
-finally terminates your license, and (b) permanently, if the copyright
-holder fails to notify you of the violation by some reasonable means
-prior to 60 days after the cessation.
-
-  Moreover, your license from a particular copyright holder is
-reinstated permanently if the copyright holder notifies you of the
-violation by some reasonable means, this is the first time you have
-received notice of violation of this License (for any work) from that
-copyright holder, and you cure the violation prior to 30 days after
-your receipt of the notice.
-
-  Termination of your rights under this section does not terminate the
-licenses of parties who have received copies or rights from you under
-this License.  If your rights have been terminated and not permanently
-reinstated, you do not qualify to receive new licenses for the same
-material under section 10.
-
-  9. Acceptance Not Required for Having Copies.
-
-  You are not required to accept this License in order to receive or
-run a copy of the Program.  Ancillary propagation of a covered work
-occurring solely as a consequence of using peer-to-peer transmission
-to receive a copy likewise does not require acceptance.  However,
-nothing other than this License grants you permission to propagate or
-modify any covered work.  These actions infringe copyright if you do
-not accept this License.  Therefore, by modifying or propagating a
-covered work, you indicate your acceptance of this License to do so.
-
-  10. Automatic Licensing of Downstream Recipients.
-
-  Each time you convey a covered work, the recipient automatically
-receives a license from the original licensors, to run, modify and
-propagate that work, subject to this License.  You are not responsible
-for enforcing compliance by third parties with this License.
-
-  An "entity transaction" is a transaction transferring control of an
-organization, or substantially all assets of one, or subdividing an
-organization, or merging organizations.  If propagation of a covered
-work results from an entity transaction, each party to that
-transaction who receives a copy of the work also receives whatever
-licenses to the work the party's predecessor in interest had or could
-give under the previous paragraph, plus a right to possession of the
-Corresponding Source of the work from the predecessor in interest, if
-the predecessor has it or can get it with reasonable efforts.
-
-  You may not impose any further restrictions on the exercise of the
-rights granted or affirmed under this License.  For example, you may
-not impose a license fee, royalty, or other charge for exercise of
-rights granted under this License, and you may not initiate litigation
-(including a cross-claim or counterclaim in a lawsuit) alleging that
-any patent claim is infringed by making, using, selling, offering for
-sale, or importing the Program or any portion of it.
-
-  11. Patents.
-
-  A "contributor" is a copyright holder who authorizes use under this
-License of the Program or a work on which the Program is based.  The
-work thus licensed is called the contributor's "contributor version".
-
-  A contributor's "essential patent claims" are all patent claims
-owned or controlled by the contributor, whether already acquired or
-hereafter acquired, that would be infringed by some manner, permitted
-by this License, of making, using, or selling its contributor version,
-but do not include claims that would be infringed only as a
-consequence of further modification of the contributor version.  For
-purposes of this definition, "control" includes the right to grant
-patent sublicenses in a manner consistent with the requirements of
-this License.
-
-  Each contributor grants you a non-exclusive, worldwide, royalty-free
-patent license under the contributor's essential patent claims, to
-make, use, sell, offer for sale, import and otherwise run, modify and
-propagate the contents of its contributor version.
-
-  In the following three paragraphs, a "patent license" is any express
-agreement or commitment, however denominated, not to enforce a patent
-(such as an express permission to practice a patent or covenant not to
-sue for patent infringement).  To "grant" such a patent license to a
-party means to make such an agreement or commitment not to enforce a
-patent against the party.
-
-  If you convey a covered work, knowingly relying on a patent license,
-and the Corresponding Source of the work is not available for anyone
-to copy, free of charge and under the terms of this License, through a
-publicly available network server or other readily accessible means,
-then you must either (1) cause the Corresponding Source to be so
-available, or (2) arrange to deprive yourself of the benefit of the
-patent license for this particular work, or (3) arrange, in a manner
-consistent with the requirements of this License, to extend the patent
-license to downstream recipients.  "Knowingly relying" means you have
-actual knowledge that, but for the patent license, your conveying the
-covered work in a country, or your recipient's use of the covered work
-in a country, would infringe one or more identifiable patents in that
-country that you have reason to believe are valid.
-
-  If, pursuant to or in connection with a single transaction or
-arrangement, you convey, or propagate by procuring conveyance of, a
-covered work, and grant a patent license to some of the parties
-receiving the covered work authorizing them to use, propagate, modify
-or convey a specific copy of the covered work, then the patent license
-you grant is automatically extended to all recipients of the covered
-work and works based on it.
-
-  A patent license is "discriminatory" if it does not include within
-the scope of its coverage, prohibits the exercise of, or is
-conditioned on the non-exercise of one or more of the rights that are
-specifically granted under this License.  You may not convey a covered
-work if you are a party to an arrangement with a third party that is
-in the business of distributing software, under which you make payment
-to the third party based on the extent of your activity of conveying
-the work, and under which the third party grants, to any of the
-parties who would receive the covered work from you, a discriminatory
-patent license (a) in connection with copies of the covered work
-conveyed by you (or copies made from those copies), or (b) primarily
-for and in connection with specific products or compilations that
-contain the covered work, unless you entered into that arrangement,
-or that patent license was granted, prior to 28 March 2007.
-
-  Nothing in this License shall be construed as excluding or limiting
-any implied license or other defenses to infringement that may
-otherwise be available to you under applicable patent law.
-
-  12. No Surrender of Others' Freedom.
-
-  If conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot convey a
-covered work so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you may
-not convey it at all.  For example, if you agree to terms that obligate you
-to collect a royalty for further conveying from those to whom you convey
-the Program, the only way you could satisfy both those terms and this
-License would be to refrain entirely from conveying the Program.
-
-  13. Use with the GNU Affero General Public License.
-
-  Notwithstanding any other provision of this License, you have
-permission to link or combine any covered work with a work licensed
-under version 3 of the GNU Affero General Public License into a single
-combined work, and to convey the resulting work.  The terms of this
-License will continue to apply to the part which is the covered work,
-but the special requirements of the GNU Affero General Public License,
-section 13, concerning interaction through a network will apply to the
-combination as such.
-
-  14. Revised Versions of this License.
-
-  The Free Software Foundation may publish revised and/or new versions of
-the GNU General Public License from time to time.  Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-  Each version is given a distinguishing version number.  If the
-Program specifies that a certain numbered version of the GNU General
-Public License "or any later version" applies to it, you have the
-option of following the terms and conditions either of that numbered
-version or of any later version published by the Free Software
-Foundation.  If the Program does not specify a version number of the
-GNU General Public License, you may choose any version ever published
-by the Free Software Foundation.
-
-  If the Program specifies that a proxy can decide which future
-versions of the GNU General Public License can be used, that proxy's
-public statement of acceptance of a version permanently authorizes you
-to choose that version for the Program.
-
-  Later license versions may give you additional or different
-permissions.  However, no additional obligations are imposed on any
-author or copyright holder as a result of your choosing to follow a
-later version.
-
-  15. Disclaimer of Warranty.
-
-  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
-APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
-HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
-OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
-THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
-PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
-IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
-ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
-
-  16. Limitation of Liability.
-
-  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
-THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
-GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
-USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
-DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
-PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
-EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
-SUCH DAMAGES.
-
-  17. Interpretation of Sections 15 and 16.
-
-  If the disclaimer of warranty and limitation of liability provided
-above cannot be given local legal effect according to their terms,
-reviewing courts shall apply local law that most closely approximates
-an absolute waiver of all civil liability in connection with the
-Program, unless a warranty or assumption of liability accompanies a
-copy of the Program in return for a fee.
-
-                     END OF TERMS AND CONDITIONS
-
-            How to Apply These Terms to Your New Programs
-
-  If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
-  To do so, attach the following notices to the program.  It is safest
-to attach them to the start of each source file to most effectively
-state the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the program's name and a brief idea of what it does.>
-    Copyright (C) <year>  <name of author>
-
-    This program is free software: you can redistribute it and/or modify
-    it under the terms of the GNU General Public License as published by
-    the Free Software Foundation, either version 3 of the License, or
-    (at your option) any later version.
-
-    This program is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
-    GNU General Public License for more details.
-
-    You should have received a copy of the GNU General Public License
-    along with this program.  If not, see <https://www.gnu.org/licenses/>.
-
-Also add information on how to contact you by electronic and paper mail.
-
-  If the program does terminal interaction, make it output a short
-notice like this when it starts in an interactive mode:
-
-    <program>  Copyright (C) <year>  <name of author>
-    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
-    This is free software, and you are welcome to redistribute it
-    under certain conditions; type `show c' for details.
-
-The hypothetical commands `show w' and `show c' should show the appropriate
-parts of the General Public License.  Of course, your program's commands
-might be different; for a GUI interface, you would use an "about box".
-
-  You should also get your employer (if you work as a programmer) or school,
-if any, to sign a "copyright disclaimer" for the program, if necessary.
-For more information on this, and how to apply and follow the GNU GPL, see
-<https://www.gnu.org/licenses/>.
-
-  The GNU General Public License does not permit incorporating your program
-into proprietary programs.  If your program is a subroutine library, you
-may consider it more useful to permit linking proprietary applications with
-the library.  If this is what you want to do, use the GNU Lesser General
-Public License instead of this License.  But first, please read
-<https://www.gnu.org/licenses/why-not-lgpl.html>.

+## 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.
