For scientific papers LaTeX is recommended for typesetting, that's why most of the templates here are designed for it. If you want to learn LaTeX less deeply, you can also use Pandoc to use the LaTeX templates with Markdown. For Word & LibreOffice there are currently no templates available for download.
