-This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
-
-## Common Development Commands
-
-### Build and Test
-- **Build project**: `./gradlew clean build`
-- **Run locally**: `./gradlew bootRun`
-- **Full test suite**: `./test.sh` (builds all Docker variants and runs comprehensive tests)
-- **Code formatting**: `./gradlew spotlessApply` (runs automatically before compilation)
-
-### Docker Development
-- **Build ultra-lite**: `docker build -t stirlingtools/stirling-pdf:latest-ultra-lite -f ./Dockerfile.ultra-lite .`
-- **Build standard**: `docker build -t stirlingtools/stirling-pdf:latest -f ./Dockerfile .`
-- **Build fat version**: `docker build -t stirlingtools/stirling-pdf:latest-fat -f ./Dockerfile.fat .`
-- **Example compose files**: Located in `exampleYmlFiles/` directory
-
-### Security Mode Development
-Set `DOCKER_ENABLE_SECURITY=true` environment variable to enable security features during development. This is required for testing the full version locally.
-
-### Frontend Development
-- **Frontend dev server**: `cd frontend && npm run dev` (requires backend on localhost:8080)
-- **Tech Stack**: Vite + React + TypeScript + Mantine UI + TailwindCSS
-- **Proxy Configuration**: Vite proxies `/api/*` calls to backend (localhost:8080)
-- **Build Process**: DO NOT run build scripts manually - builds are handled by CI/CD pipelines
-- **Package Installation**: DO NOT run npm install commands - package management handled separately
-- **Deployment Options**:
-  - **Desktop App**: `npm run tauri-build` (native desktop application)
-  - **Web Server**: `npm run build` then serve dist/ folder
-  - **Development**: `npm run tauri-dev` for desktop dev mode
-
-#### Multi-Tool Workflow Architecture
-Frontend designed for **stateful document processing**:
-- Users upload PDFs once, then chain tools (split → merge → compress → view)
-- File state and processing results persist across tool switches
-- No file reloading between tools - performance critical for large PDFs (up to 100GB+)
-
-#### FileContext - Central State Management
-**Location**: `src/contexts/FileContext.tsx`
-- **Active files**: Currently loaded PDFs and their variants
-- **Tool navigation**: Current mode (viewer/pageEditor/fileEditor/toolName)  
-- **Memory management**: PDF document cleanup, blob URL lifecycle, Web Worker management
-- **IndexedDB persistence**: File storage with thumbnail caching
-- **Preview system**: Tools can preview results (e.g., Split → Viewer → back to Split) without context pollution

-**Critical**: All file operations go through FileContext. Don't bypass with direct file handling.
-
-#### Processing Services
-- **enhancedPDFProcessingService**: Background PDF parsing and manipulation
-- **thumbnailGenerationService**: Web Worker-based with main-thread fallback
-- **fileStorage**: IndexedDB with LRU cache management
-
-#### Memory Management Strategy
-**Why manual cleanup exists**: Large PDFs (up to 100GB+) through multiple tools accumulate:
-- PDF.js documents that need explicit .destroy() calls
-- Blob URLs from tool outputs that need revocation
-- Web Workers that need termination
-Without cleanup: browser crashes with memory leaks.
-
-#### Tool Development
-- **Pattern**: Follow `src/tools/Split.tsx` as reference implementation
-- **File Access**: Tools receive `selectedFiles` prop (computed from activeFiles based on user selection)
-- **File Selection**: Users select files in FileEditor (tool mode) → stored as IDs → computed to File objects for tools
-- **Integration**: All files are part of FileContext ecosystem - automatic memory management and operation tracking
-- **Parameters**: Tool parameter handling patterns still being standardized
-- **Preview Integration**: Tools can implement preview functionality (see Split tool's thumbnail preview)
-
-## Architecture Overview
-
-### Project Structure
-- **Backend**: Spring Boot application with Thymeleaf templating
-- **Frontend**: React-based SPA in `/frontend` directory (Thymeleaf templates fully replaced)
-  - **File Storage**: IndexedDB for client-side file persistence and thumbnails
-  - **Internationalization**: JSON-based translations (converted from backend .properties)
-- **PDF Processing**: PDFBox for core PDF operations, LibreOffice for conversions, PDF.js for client-side rendering
-- **Security**: Spring Security with optional authentication (controlled by `DOCKER_ENABLE_SECURITY`)
-- **Configuration**: YAML-based configuration with environment variable overrides
-
-### Controller Architecture
-- **API Controllers** (`src/main/java/.../controller/api/`): REST endpoints for PDF operations
-  - Organized by function: converters, security, misc, pipeline
-  - Follow pattern: `@RestController` + `@RequestMapping("/api/v1/...")`
-- **Web Controllers** (`src/main/java/.../controller/web/`): Serve Thymeleaf templates
-  - Pattern: `@Controller` + return template names
-
-### Key Components
-- **SPDFApplication.java**: Main application class with desktop UI and browser launching logic
-- **ConfigInitializer**: Handles runtime configuration and settings files
-- **Pipeline System**: Automated PDF processing workflows via `PipelineController`
-- **Security Layer**: Authentication, authorization, and user management (when enabled)
-
-### Component Architecture
-- **React Components**: Located in `frontend/src/components/` and `frontend/src/tools/`
-- **Static Assets**: CSS, JS, and resources in `src/main/resources/static/` (legacy) + `frontend/public/` (modern)
-- **Internationalization**:
-  - Backend: `messages_*.properties` files
-  - Frontend: JSON files in `frontend/public/locales/` (converted from .properties)
-  - Conversion Script: `scripts/convert_properties_to_json.py`
-
-### Configuration Modes
-- **Ultra-lite**: Basic PDF operations only
-- **Standard**: Full feature set
-- **Fat**: Pre-downloaded dependencies for air-gapped environments
-- **Security Mode**: Adds authentication, user management, and enterprise features
-
-### Testing Strategy
-- **Integration Tests**: Cucumber tests in `testing/cucumber/`
-- **Docker Testing**: `test.sh` validates all Docker variants
-- **Manual Testing**: No unit tests currently - relies on UI and API testing
-
-## Development Workflow
-
-1. **Local Development**:
-   - Backend: `./gradlew bootRun` (runs on localhost:8080)
-   - Frontend: `cd frontend && npm run dev` (runs on localhost:5173, proxies to backend)
-2. **Docker Testing**: Use `./test.sh` before submitting PRs
-3. **Code Style**: Spotless enforces Google Java Format automatically
-4. **Translations**:
-   - Backend: Use helper scripts in `/scripts` for multi-language updates
-   - Frontend: Update JSON files in `frontend/public/locales/` or use conversion script
-5. **Documentation**: API docs auto-generated and available at `/swagger-ui/index.html`
-
-## Frontend Architecture Status
-
-- **Core Status**: React SPA architecture complete with multi-tool workflow support
-- **State Management**: FileContext handles all file operations and tool navigation  
-- **File Processing**: Production-ready with memory management for large PDF workflows (up to 100GB+)
-- **Tool Integration**: Standardized tool interface - see `src/tools/Split.tsx` as reference
-- **Preview System**: Tool results can be previewed without polluting file context (Split tool example)
-- **Performance**: Web Worker thumbnails, IndexedDB persistence, background processing
-
-## Important Notes
-
-- **Java Version**: Minimum JDK 17, supports and recommends JDK 21
-- **Lombok**: Used extensively - ensure IDE plugin is installed
-- **Desktop Mode**: Set `STIRLING_PDF_DESKTOP_UI=true` for desktop application mode
-- **File Persistence**:
-  - **Backend**: Designed to be stateless - files are processed in memory/temp locations only
-  - **Frontend**: Uses IndexedDB for client-side file storage and caching (with thumbnails)
-- **Security**: When `DOCKER_ENABLE_SECURITY=false`, security-related classes are excluded from compilation
-- **FileContext**: All file operations MUST go through FileContext - never bypass with direct File handling
-- **Memory Management**: Manual cleanup required for PDF.js documents and blob URLs - don't remove cleanup code
-- **Tool Development**: New tools should follow Split tool pattern (`src/tools/Split.tsx`)
-- **Performance Target**: Must handle PDFs up to 100GB+ without browser crashes
-- **Preview System**: Tools can preview results without polluting main file context (see Split tool implementation)
-
-## Communication Style
-- Be direct and to the point
-- No apologies or conversational filler
-- Answer questions directly without preamble
-- Explain reasoning concisely when asked
-- Avoid unnecessary elaboration
-
-## Decision Making
-- Ask clarifying questions before making assumptions
-- Stop and ask when uncertain about project-specific details
-- Confirm approach before making structural changes
-- Request guidance on preferences (cross-platform vs specific tools, etc.)
-- Verify understanding of requirements before proceeding

-# Stirling-PDF Developer Guide
-
-## 1. Introduction
-
-Stirling-PDF is a robust, locally hosted, web-based PDF manipulation tool. **Stirling 2.0** represents a complete frontend rewrite, replacing the legacy Thymeleaf-based UI with a modern React SPA (Single Page Application).
-
-This guide focuses on developing for Stirling 2.0, including both the React frontend and Spring Boot backend development workflows.
-
-## 2. Project Overview
-
-**Stirling 2.0** is built using:
-
-**Backend:**
-- Spring Boot (Java 17+, JDK 21 recommended)
-- PDFBox for core PDF operations
-- LibreOffice for document conversions
-- qpdf for PDF optimization
-- Spring Security (optional, controlled by `DOCKER_ENABLE_SECURITY`)
-- Lombok for reducing boilerplate code
-
-**Frontend (React SPA):**
-- React + TypeScript
-- Vite for build tooling and development server
-- Mantine UI component library
-- TailwindCSS for styling
-- PDF.js for client-side PDF rendering
-- PDF-LIB.js for client-side PDF manipulation
-- IndexedDB for client-side file storage and thumbnails
-- i18next for internationalization
-
-**Infrastructure:**
-- Docker for containerization
-- Gradle for build management
-
-**Legacy (reference only during development):**
-- Thymeleaf templates (being completely replaced in 2.0)
-
-## 3. Development Environment Setup
-
-### Prerequisites
-
-- Docker
-- Git
-- Java JDK 17 or later (JDK 21 recommended)
-- Node.js 18+ and npm (required for frontend development)
-- Gradle 7.0 or later (Included within the repo)
-
-### Setup Steps
-
-1. Clone the repository:
-
-   ```bash
-   git clone https://github.com/Stirling-Tools/Stirling-PDF.git
-   cd Stirling-PDF
-   ```
-
-2. Install Docker and JDK17 if not already installed.
-
-3. Install a recommended Java IDE such as Eclipse, IntelliJ, or VSCode
-   1. Only VSCode
-      1. Open VS Code.
-      2. When prompted, install the recommended extensions.
-      3. Alternatively, open the command palette (`Ctrl + Shift + P` or `Cmd + Shift + P` on macOS) and run:
-
-        ```sh
-        Extensions: Show Recommended Extensions
-        ```
-
-      4. Install the required extensions from the list.
-
-4. Lombok Setup
-Stirling-PDF uses Lombok to reduce boilerplate code. Some IDEs, like Eclipse, don't support Lombok out of the box. To set up Lombok in your development environment:
-Visit the [Lombok website](https://projectlombok.org/setup/) for installation instructions specific to your IDE.
-
-5. Add environment variable
-For local testing, you should generally be testing the full 'Security' version of Stirling PDF. To do this, you must add the environment flag DISABLE_ADDITIONAL_FEATURES=false to your system and/or IDE build/run step.
-5. **Frontend Setup (Required for Stirling 2.0)**
-   Navigate to the frontend directory and install dependencies using npm.
-
-## 4. Stirling 2.0 Development Workflow
-
-### Frontend Development (React)
-The frontend is a React SPA that runs independently during development:
-
-1. **Start the backend**: Run the Spring Boot application (serves API endpoints on localhost:8080)
-2. **Start the frontend dev server**: Navigate to the frontend directory and run the development server (serves UI on localhost:5173)
-3. **Development flow**: The Vite dev server automatically proxies API calls to the backend
-
-### File Storage Architecture
-Stirling 2.0 uses client-side file storage:
-- **IndexedDB**: Stores files locally in the browser with automatic thumbnail generation
-- **PDF.js**: Handles client-side PDF rendering and processing
-- **URL Parameters**: Support for deep linking and tool state persistence
-
-### Legacy Code Reference
-The existing Thymeleaf templates remain in the codebase during development as reference material but will be completely removed for the 2.0 release.

-
-## 6. Docker-based Development
-
-Stirling-PDF offers several Docker versions:
-
-- Full: All features included
-- Ultra-Lite: Basic PDF operations only
-- Fat: Includes additional libraries and fonts predownloaded
-
-### Example Docker Compose Files
-
-Stirling-PDF provides several example Docker Compose files in the `exampleYmlFiles` directory, such as:
-
-- `docker-compose-latest.yml`: Latest version without login and security features
-- `docker-compose-latest-security.yml`: Latest version with login and security features enabled
-- `docker-compose-latest-fat-security.yml`: Fat version with login and security features enabled
-
-These files provide pre-configured setups for different scenarios. For example, here's a snippet from `docker-compose-latest-security.yml`:
-
-```yaml
-services:
-  stirling-pdf:
-    container_name: Stirling-PDF-Security
-    image: docker.stirlingpdf.com/stirlingtools/stirling-pdf:latest
-    deploy:
-      resources:
-        limits:
-          memory: 4G
-    healthcheck:
-      test: ["CMD-SHELL", "curl -f http://localhost:8080/api/v1/info/status | grep -q 'UP' && curl -fL http://localhost:8080/ | grep -q 'Please sign in'"]
-      interval: 5s
-      timeout: 10s
-      retries: 16
-    ports:
-      - "8080:8080"
-    volumes:
-      - ./stirling/latest/data:/usr/share/tessdata:rw
-      - ./stirling/latest/config:/configs:rw
-      - ./stirling/latest/logs:/logs:rw
-    environment:
-      DISABLE_ADDITIONAL_FEATURES: "false"
-      SECURITY_ENABLELOGIN: "true"
-      PUID: 1002
-      PGID: 1002
-      UMASK: "022"
-      SYSTEM_DEFAULTLOCALE: en-US
-      UI_APPNAME: Stirling-PDF
-      UI_HOMEDESCRIPTION: Demo site for Stirling-PDF Latest with Security
-      UI_APPNAMENAVBAR: Stirling-PDF Latest
-      SYSTEM_MAXFILESIZE: "100"
-      METRICS_ENABLED: "true"
-      SYSTEM_GOOGLEVISIBILITY: "true"
-      SHOW_SURVEY: "true"
-    restart: on-failure:5
-```
-
-To use these example files, copy the desired file to your project root and rename it to `docker-compose.yml`, or specify the file explicitly when running Docker Compose:
-
-```bash
-docker-compose -f exampleYmlFiles/docker-compose-latest-security.yml up
-```
-
-### Building Docker Images
-
-Stirling-PDF uses different Docker images for various configurations. The build process is controlled by environment variables and uses specific Dockerfile variants. Here's how to build the Docker images:
-
-1. Set the security environment variable:
-
-   ```bash
-   export DISABLE_ADDITIONAL_FEATURES=true  # or false for to enable login and security features for builds
-   ```
-
-2. Build the project with Gradle:
-
-   ```bash
-   ./gradlew clean build
-   ```
-
-3. Build the Docker images:
-
-   For the latest version:
-
-   ```bash
-   docker build --no-cache --pull --build-arg VERSION_TAG=alpha -t stirlingtools/stirling-pdf:latest -f ./Dockerfile .
-   ```
-
-   For the ultra-lite version:
-
-   ```bash
-   docker build --no-cache --pull --build-arg VERSION_TAG=alpha -t stirlingtools/stirling-pdf:latest-ultra-lite -f ./Dockerfile.ultra-lite .
-   ```
-
-   For the fat version (with login and security features enabled):
-
-   ```bash
-   export DISABLE_ADDITIONAL_FEATURES=false
-   docker build --no-cache --pull --build-arg VERSION_TAG=alpha -t stirlingtools/stirling-pdf:latest-fat -f ./Dockerfile.fat .
-   ```
-
-Note: The `--no-cache` and `--pull` flags ensure that the build process uses the latest base images and doesn't use cached layers, which is useful for testing and ensuring reproducible builds. however to improve build times these can often be removed depending on your usecase
-
-## 7. Testing
-
-### Comprehensive Testing Script
-
-Stirling-PDF provides a `test.sh` script in the root directory. This script builds all versions of Stirling-PDF, checks that each version works, and runs Cucumber tests. It's recommended to run this script before submitting a final pull request.
-
-To run the test script:
-
-```bash
-./test.sh
-```
-
-This script performs the following actions:
-
-1. Builds all Docker images (full, ultra-lite, fat).
-2. Runs each version to ensure it starts correctly.
-3. Executes Cucumber tests against the main version and ensures feature compatibility. In the event these tests fail, your PR will not be merged.
-
-Note: The `test.sh` script will run automatically when you raise a PR. However, it's recommended to run it locally first to save resources and catch any issues early.
-
-### Full Testing with Docker
-
-1. Build and run the Docker container per the above instructions:
-
-2. Access the application at `http://localhost:8080` and manually test all features developed.
-
-### Frontend Development Testing (Stirling 2.0)
-
-For React frontend development:
-
-1. Start the backend: Run the Spring Boot application to serve API endpoints on localhost:8080
-2. Start the frontend dev server: Navigate to the frontend directory and run the development server on localhost:5173
-3. The Vite dev server automatically proxies API calls to the backend
-4. Test React components, UI interactions, and IndexedDB file operations using browser developer tools
-
-### Local Testing (Java and UI Components)
-
-For quick iterations and development of Java backend, JavaScript, and UI components, you can run and test Stirling-PDF locally without Docker. This approach allows you to work on and verify changes to:
-
-- Java backend logic
-- RESTful API endpoints
-- JavaScript functionality
-- User interface components and styling
-- Thymeleaf templates
-
-To run Stirling-PDF locally:
-
-1. Compile and run the project using built-in IDE methods or by running:
-
-   ```bash
-   ./gradlew bootRun
-   ```
-
-2. Access the application at `http://localhost:8080` in your web browser.
-
-3. Manually test the features you're working on through the UI.
-
-4. For API changes, use tools like Postman or curl to test endpoints directly.
-
-Important notes:
-
-- Local testing doesn't include features that depend on external tools like qpdf, LibreOffice, or Python scripts.
-- There are currently no automated unit tests. All testing is done manually through the UI or API calls. (You are welcome to add JUnits!)
-- Always verify your changes in the full Docker environment before submitting pull requests, as some integrations and features will only work in the complete setup.
-
-## 8. Contributing
-
-1. Fork the repository on GitHub.
-2. Create a new branch for your feature or bug fix.
-3. Make your changes and commit them with clear, descriptive messages and ensure any documentation is updated related to your changes.
-4. Test your changes thoroughly in the Docker environment.
-5. Run the `test.sh` script to ensure all versions build correctly and pass the Cucumber tests:
-
-   ```bash
-   ./test.sh
-   ```
-
-6. Push your changes to your fork.
-7. Submit a pull request to the main repository.
-8. See additional [contributing guidelines](https://github.com/Stirling-Tools/Stirling-PDF/blob/main/CONTRIBUTING.md).
-
-When you raise a PR:
-
-- The `test.sh` script will run automatically against your PR.
-- The PR checks will verify versioning and dependency updates.
-- Documentation will be automatically updated for dependency changes.
-- Security issues will be checked using Snyk and PixeeBot.
-
-Address any issues that arise from these checks before finalizing your pull request.
-
-## 9. API Documentation
-
-API documentation is available at `/swagger-ui/index.html` when running the application. You can also view the latest API documentation [here](https://app.swaggerhub.com/apis-docs/Stirling-Tools/Stirling-PDF/).
-
-## 10. Customization
-
-Stirling-PDF can be customized through environment variables or a `settings.yml` file. Key customization options include:
-
-- Application name and branding
-- Security settings
-- UI customization
-- Endpoint management
-
-When using Docker, pass environment variables using the `-e` flag or in your `docker-compose.yml` file.
-
-Example:
-
-```bash
-docker run -p 8080:8080 -e APP_NAME="My PDF Tool" stirling-pdf:full
-```
-
-Refer to the main README for a full list of customization options.
-
-## 11. Language Translations
-
-For managing language translations that affect multiple files, Stirling-PDF provides a helper script:
-
-```bash
-/scripts/replace_translation_line.sh
-```
-
-This script helps you make consistent replacements across language files.
-
-When contributing translations:
-
-1. Use the helper script for multi-file changes.
-2. Ensure all language files are updated consistently.
-3. The PR checks will verify consistency in language file updates.
-
-Remember to test your changes thoroughly to ensure they don't break any existing functionality.
-
-## Code examples
-
-### React Component Development (Stirling 2.0)
-
-For Stirling 2.0, new features are built as React components instead of Thymeleaf templates:
-
-#### Creating a New Tool Component
-
-1. **Create the React Component:**
-   ```typescript
-   // frontend/src/tools/NewTool.tsx
-   import { useState } from 'react';
-   import { Button, FileInput, Container } from '@mantine/core';
-   
-   interface NewToolProps {
-     params: Record<string, any>;
-     updateParams: (updates: Record<string, any>) => void;
-   }
-   
-   export default function NewTool({ params, updateParams }: NewToolProps) {
-     const [files, setFiles] = useState<File[]>([]);
-     
-     const handleProcess = async () => {
-       // Process files using API or client-side logic
-     };
-     
-     return (
-       <Container>
-         <FileInput 
-           multiple 
-           accept="application/pdf"
-           onChange={setFiles}
-         />
-         <Button onClick={handleProcess}>Process</Button>
-       </Container>
-     );
-   }
-   ```
-
-2. **Add API Integration:**
-   ```typescript
-   // Use existing API endpoints or create new ones
-   const response = await fetch('/api/v1/new-tool', {
-     method: 'POST',
-     body: formData
-   });
-   ```
-
-3. **Register in Tool Picker:**
-   Update the tool picker component to include the new tool with proper routing and URL parameter support.
-
-### Legacy Reference: Overview of Thymeleaf
-
-Thymeleaf is a server-side Java HTML template engine. It is used in Stirling-PDF to render dynamic web pages. Thymeleaf integrates heavily with Spring Boot.
-
-### Thymeleaf overview
-
-In Stirling-PDF, Thymeleaf is used to create HTML templates that are rendered on the server side. These templates are located in the `stirling-pdf/src/main/resources/templates` directory. Thymeleaf templates use a combination of HTML and special Thymeleaf attributes to dynamically generate content.
-
-Some examples of this are:
-
-```html
-<th:block th:insert="~{fragments/navbar.html :: navbar}"></th:block>
-```
-or
-```html
-<th:block th:insert="~{fragments/footer.html :: footer}"></th:block>
-```
-
-Where it uses the `th:block`, `th:` indicating it's a special Thymeleaf element to be used server-side in generating the HTML, and block being the actual element type.
-In this case, we are inserting the `navbar` entry within the `fragments/navbar.html` fragment into the `th:block` element.
-
-They can be more complex, such as:
-
-```html
-<th:block th:insert="~{fragments/common :: head(title=#{pageExtracter.title}, header=#{pageExtracter.header})}"></th:block>
-```
-
-Which is the same as above but passes the parameters title and header into the fragment `common.html` to be used in its HTML generation.
-
-Thymeleaf can also be used to loop through objects or pass things from the Java side into the HTML side.
-
-```java
- @GetMapping
-       public String newFeaturePage(Model model) {
-           model.addAttribute("exampleData", exampleData);
-           return "new-feature";
-       }
-```
-
-In the above example, if exampleData is a list of plain java objects of class Person and within it, you had id, name, age, etc. You can reference it like so
-
-```html
-<tbody>
-   <!-- Use th:each to iterate over the list -->
-   <tr th:each="person : ${exampleData}">
-       <td th:text="${person.id}"></td>
-       <td th:text="${person.name}"></td>
-       <td th:text="${person.age}"></td>
-       <td th:text="${person.email}"></td>
-   </tr>
-</tbody>
-```
-

-### Adding a New Feature to the Backend (API)
-
-1. **Create a New Controller:**
-   - Create a new Java class in the `stirling-pdf/src/main/java/stirling/software/SPDF/controller/api` directory.
-   - Annotate the class with `@RestController` and `@RequestMapping` to define the API endpoint.
-   - Ensure to add API documentation annotations like `@Tag(name = "General", description = "General APIs")` and `@Operation(summary = "Crops a PDF document", description = "This operation takes an input PDF file and crops it according to the given coordinates. Input:PDF Output:PDF Type:SISO")`.
-
-   ```java
-   package stirling.software.SPDF.controller.api;
-
-   import org.springframework.web.bind.annotation.GetMapping;
-   import org.springframework.web.bind.annotation.RequestMapping;
-   import org.springframework.web.bind.annotation.RestController;
-   import io.swagger.v3.oas.annotations.Operation;
-   import io.swagger.v3.oas.annotations.tags.Tag;
-
-   @RestController
-   @RequestMapping("/api/v1/new-feature")
-   @Tag(name = "General", description = "General APIs")
-   public class NewFeatureController {
-
-       @GetMapping
-       @Operation(summary = "New Feature", description = "This is a new feature endpoint.")
-       public String newFeature() {
-           return "NewFeatureResponse"; // This refers to the NewFeatureResponse.html template presenting the user with the generated html from that file when they navigate to /api/v1/new-feature
-       }
-   }
-   ```
-
-2. **Define the Service Layer:** (Not required but often useful)
-   - Create a new service class in the `stirling-pdf/src/main/java/stirling/software/SPDF/service` directory.
-   - Implement the business logic for the new feature.
-
-   ```java
-   package stirling.software.SPDF.service;
-
-   import org.springframework.stereotype.Service;
-
-   @Service
-   public class NewFeatureService {
-
-       public String getNewFeatureData() {
-           // Implement business logic here
-           return "New Feature Data";
-       }
-   }
-   ```
-
-2b. **Integrate the Service with the Controller:**
-
-- Autowire the service class in the controller and use it to handle the API request.
-
-  ```java
-  package stirling.software.SPDF.controller.api;
-
-  import org.springframework.beans.factory.annotation.Autowired;
-  import org.springframework.web.bind.annotation.GetMapping;
-  import org.springframework.web.bind.annotation.RequestMapping;
-  import org.springframework.web.bind.annotation.RestController;
-  import stirling.software.SPDF.service.NewFeatureService;
-  import io.swagger.v3.oas.annotations.Operation;
-  import io.swagger.v3.oas.annotations.tags.Tag;
-
-  @RestController
-  @RequestMapping("/api/v1/new-feature")
-  @Tag(name = "General", description = "General APIs")
-  public class NewFeatureController {
-
-      @Autowired
-      private NewFeatureService newFeatureService;
-
-      @GetMapping
-      @Operation(summary = "New Feature", description = "This is a new feature endpoint.")
-      public String newFeature() {
-          return newFeatureService.getNewFeatureData();
-      }
-  }
-  ```
-
-### Adding a New Feature to the Frontend (UI)
-
-1. **Create a New Thymeleaf Template:**
-   - Create a new HTML file in the `stirling-pdf/src/main/resources/templates` directory.
-   - Use Thymeleaf attributes to dynamically generate content.
-   - Use `extract-page.html` as a base example for the HTML template, which is useful to ensure importing of the general layout, navbar, and footer.
-
-   ```html
-   <!DOCTYPE html>
-   <html th:lang="${#locale.language}" th:dir="#{language.direction}" th:data-language="${#locale.toString()}" xmlns:th="https://www.thymeleaf.org">
-     <head>
-     <th:block th:insert="~{fragments/common :: head(title=#{newFeature.title}, header=#{newFeature.header})}"></th:block>
-     </head>
-
-     <body>
-       <div id="page-container">
-         <div id="content-wrap">
-           <th:block th:insert="~{fragments/navbar.html :: navbar}"></th:block>
-           <br><br>
-           <div class="container">
-             <div class="row justify-content-center">
-               <div class="col-md-6 bg-card">
-                 <div class="tool-header">
-                   <span class="material-symbols-rounded tool-header-icon organize">upload</span>
-                   <span class="tool-header-text" th:text="#{newFeature.header}"></span>
-                 </div>
-                 <form th:action="@{'/api/v1/new-feature'}" method="post" enctype="multipart/form-data">
-                   <div th:replace="~{fragments/common :: fileSelector(name='fileInput', multipleInputsForSingleRequest=false, accept='application/pdf')}"></div>
-                   <input type="hidden" id="customMode" name="customMode" value="">
-                   <div class="mb-3">
-                     <label for="featureInput" th:text="#{newFeature.prompt}"></label>
-                     <input type="text" class="form-control" id="featureInput" name="featureInput" th:placeholder="#{newFeature.placeholder}" required>
-                   </div>
-
-                   <button type="submit" id="submitBtn" class="btn btn-primary" th:text="#{newFeature.submit}"></button>
-                 </form>
-               </div>
-             </div>
-           </div>
-         </div>
-         <th:block th:insert="~{fragments/footer.html :: footer}"></th:block>
-       </div>
-     </body>
-   </html>
-   ```
-
-2. **Create a New Controller for the UI:**
-   - Create a new Java class in the `stirling-pdf/src/main/java/stirling/software/SPDF/controller/ui` directory.
-   - Annotate the class with `@Controller` and `@RequestMapping` to define the UI endpoint.
-
-   ```java
-   package stirling.software.SPDF.controller.ui;
-
-   import org.springframework.beans.factory.annotation.Autowired;
-   import org.springframework.stereotype.Controller;
-   import org.springframework.ui.Model;
-   import org.springframework.web.bind.annotation.GetMapping;
-   import org.springframework.web.bind.annotation.RequestMapping;
-   import stirling.software.SPDF.service.NewFeatureService;
-
-   @Controller
-   @RequestMapping("/new-feature")
-   public class NewFeatureUIController {
-
-       @Autowired
-       private NewFeatureService newFeatureService;
-
-       @GetMapping
-       public String newFeaturePage(Model model) {
-           model.addAttribute("newFeatureData", newFeatureService.getNewFeatureData());
-           return "new-feature";
-       }
-   }
-   ```
-
-3. **Update the Navigation Bar:**
-   - Add a link to the new feature page in the navigation bar.
-   - Update the `stirling-pdf/src/main/resources/templates/fragments/navbar.html` file.
-
-   ```html
-   <li class="nav-item">
-       <a class="nav-link" th:href="@{'/new-feature'}">New Feature</a>
-   </li>
-   ```
-
-## Adding New Translations to Existing Language Files in Stirling-PDF
-
-When adding a new feature or modifying existing ones in Stirling-PDF, you'll need to add new translation entries to the existing language files. Here's a step-by-step guide:
-
-### 1. Locate Existing Language Files
-
-Find the existing `messages.properties` files in the `stirling-pdf/src/main/resources` directory. You'll see files like:
-
-- `messages.properties` (default, usually English)
-- `messages_en_GB.properties`
-- `messages_fr_FR.properties`
-- `messages_de_DE.properties`
-- etc.
-
-### 2. Add New Translation Entries
-
-Open each of these files and add your new translation entries. For example, if you're adding a new feature called "PDF Splitter",
-Use descriptive, hierarchical keys (e.g., `feature.element.description`)
-you might add:
-
-```properties
-pdfSplitter.title=PDF Splitter
-pdfSplitter.description=Split your PDF into multiple documents
-pdfSplitter.button.split=Split PDF
-pdfSplitter.input.pages=Enter page numbers to split
-```
-
-Add these entries to the default GB language file and any others you wish, translating the values as appropriate for each language.
-
-### 3. Use Translations in Thymeleaf Templates
-
-In your Thymeleaf templates, use the `#{key}` syntax to reference the new translations:
-
-```html
-<h1 th:text="#{pdfSplitter.title}">PDF Splitter</h1>
-<p th:text="#{pdfSplitter.description}">Split your PDF into multiple documents</p>
-<input type="text" th:placeholder="#{pdfSplitter.input.pages}">
-<button th:text="#{pdfSplitter.button.split}">Split PDF</button>
-```
-
-Remember, never hard-code text in your templates or Java code. Always use translation keys to ensure proper localization.
