What Remark is

Remark is a free, MIT-licensed slideshow tool that turns Markdown into presentations in a web browser. It is designed for people comfortable with HTML and CSS. Users create an HTML file, separate slides with three dashes, and open the file in a browser, where JavaScript renders the presentation. Markdown extensions provide slide properties for names, styling, and templates, plus content classes and syntax highlighting for supported languages. Slides are intended to scale across devices and resolutions, and touch support includes swipe navigation on phones and tablets. Presenter mode is available. When required resources are stored locally, the HTML slideshow can work offline. Files can be hosted on services such as Dropbox or GitHub Pages, while Git or Mercurial can track changes. PDF output is primarily documented through Chrome Print to PDF, with DeckTape also mentioned.
