Quarto is an open-source scientific and technical publishing system built on Pandoc. Quarto documents are authored using markdown, an easy to write plain text format.

In addition to the core capabilities of Pandoc, Quarto includes:

1. Embedding code and output from Python, R, Julia, and JavaScript via integration with Jupyter, Knitr, and Observable.
2. A variety of extensions to Pandoc markdown useful for technical writing including cross-references, sub-figures, layout panels, hoverable citations and footnotes, callouts, and more.
3. A project system for rendering groups of documents at once, sharing options across documents, and producing aggregate output like websites and books.
4. Authoring using a wide variety of editors and notebooks including JupyterLab, RStudio, and VS Code.
5. A visual markdown editor that provides a productive writing interface for composing long-form documents.
