   • Copy the downloaded .traineddata file to the tessdata directory of your Tesseract installation (e.g., C:\Program Files\Tesseract-OCR\tessdata).

2. macOS (not tested):

   • Use Homebrew to install the language pack:

     brew install tesseract-lang

3. Linux (Ubuntu) (not tested):

   • Use your package manager to install the language pack. For example, to install the French language pack:

     sudo apt-get install tesseract-ocr-fra
