 Stirling PDF provides Windows compatibility through a downloadable .exe file, which can be obtained from [here](https://github.com/Stirling-Tools/Stirling-PDF/releases/latest).
 This is a streamlined version of the application, offering the same capabilities as the Stirling-PDF-Ultra-lite found in Docker, but in a compact 80MB executable!
 
-Simply download and launch the .exe file to access the Stirling-PDF Web-UI. It is important to note that this application requires JAVA 17 or 21. If the application identifies that this version of JAVA isn't installed on your system, it will prompt a link to download the appropriate version.
+## Prerequisites
 
-Once launched, the application hosts a web server that is accessible and usable by anyone on your network.
+### Required Dependencies
+- JAVA 17 or 21 (21 preferred) - If not installed, the application will provide a download link
+  - Download from [Oracle's official site](https://www.oracle.com/java/technologies/downloads/) or [Eclipse Temurin](https://adoptium.net/temurin/releases/)
+
+### Optional Dependencies
+These dependencies enable additional features in Stirling PDF. Install only the ones you need:
+
+#### QPDF
+- Download from [QPDF's official site](https://qpdf.sourceforge.io/)

+3. Add to settings.yml in your Stirling PDF installation directory:
+   ```yaml
+   system:
+     tessdataDir: C:\\Program Files\\Tesseract-OCR\\tessdata
+   ```
+- Enables OCR functionality for PDFs
+
+#### Weasyprint
+1. Download from [Weasyprint's releases](https://github.com/Kozea/WeasyPrint/releases)
+2. Create a directory (e.g., `c:\weasyprint\`) and place weasyprint.exe there
+- Enables URL to PDF conversion
+- Note: Some antivirus software may flag weasyprint.exe - you may need to whitelist it
+
+#### PDFtoHTML
+1. Download from [SourceForge](https://sourceforge.net/projects/pdftohtml/)
+2. Create a directory (e.g., `c:\pdftohtml\`) and place pdftohtml.exe there

+
+## Adding Directories to System PATH
+
+After installing dependencies, you'll need to add their directories to your system's PATH. Here's how:
+
+1. Open Windows Search (Windows key + S)
+2. Type "Environment Variables" and click "Edit the system environment variables"
+3. Click "Environment Variables" button at the bottom
+4. Under "System variables", find and select "Path"
+5. Click "Edit"
+6. Click "New" to add each required path:
+   - For LibreOffice: `C:\Program Files\LibreOffice\program`
+   - For Tesseract: `C:\Program Files\Tesseract-OCR`
+   - For Weasyprint: `C:\weasyprint` (or your chosen directory)
+   - For PDFtoHTML: `C:\pdftohtml` (or your chosen directory)
+   - For QPDF: The installation directory (usually `C:\Program Files\qpdf\bin`)
+7. Click "OK" on all windows to save changes
+
+## Installation Steps
+
+1. Download the latest Stirling PDF .exe from the [releases page](https://github.com/Stirling-Tools/Stirling-PDF/releases/latest)
+2. Install any desired optional dependencies following the instructions above
+3. Launch the Stirling PDF executable
+4. Access the web interface through your browser (the application will provide the URL)
+
+## Notes
+- The application hosts a web server that is accessible to anyone on your network
+- If you install multiple Python-based dependencies, ensure they're using the same Python installation to avoid conflicts
+- Make sure to restart Stirling PDF after installing new dependencies or modifying PATH variables
+- Some features will be unavailable until their required dependencies are installed
+- The web interface will indicate which features require additional dependencies
+
+## Troubleshooting
+
+1. Verifying PATH Settings:
+   - Open Command Prompt (cmd)
+   - Type `echo %PATH%` to see all directories in your PATH
+   - For each dependency, try running its command (e.g., `tesseract --version`) to verify it's accessible
+
+2. Common Issues:
+   - If changes to PATH don't take effect, try:
+     - Logging out and back in
+     - Restarting your computer
+     - Opening a new Command Prompt window
+   - If a dependency isn't found, double-check the exact path in File Explorer
+   - For Tesseract issues, verify the tessdata directory contains language files
+   - For LibreOffice conversions, ensure no LibreOffice windows are open when converting
