Quarto is a tool for producing PDF, Word document, HTML web pages, ePub files, slideshows and many, many more output based on a Markdown file.
Using Quarto, you can render any markdown content to a new PDF f.i.
Quarto supports a very large number of features, to which are added extensions from its community, making it a really practical tool for anyone wishing to produce documentation.
Personally, I haven't used a Word-type word processor for several years; nor have I used PowerPoint since, I don't even know when the last time was.
And yet, I produce a great deal of documentation and slideshows. I write everything in markdown and generate pdfs or slideshows from the same content.
Until recently, I'd been using pandoc but, having taken the time to look around Quarto, it's a hell of a lot more powerful.
