If you are an R Markdown user wondering about the relationship between Quarto and R Markdown, see also our FAQ for R Markdown Users.

What can I use Quarto for?
Quarto® is an open-source scientific and technical publishing system built on Pandoc. You can weave together narrative text and code to produce elegantly formatted output as documents, web pages, blog posts, books and more. 



How do I install Quarto?
Visit the Quarto.org Get Started page, which provides installation instructions for Windows, Mac OS, and Linux. 



Is Quarto free to use?
Yes! Quarto is open source with a GPL-2 license. You can use or disseminate it any way that you would any GPL-2 licensed open source software. 


What output formats can Quarto create?
There are many output formats available in Quarto. This includes all of the built in Pandoc formats (e.g. HTML, PDF, MS Word, Revealjs, ePub, etc.) as well as various ways to publish multiple documents (websites, blogs, and books). Learn more at Quarto Formats. 


What editing tools can I use with Quarto?
You can use a wide variety of tools with Quarto. We have provided documentation for writing and editing Quarto documents in VSCode, JupyterLab, RStudio IDE, or any text editor. Visit the Get Started with Quarto page to install, and then choose your tool for a brief introductory guide.


Can I use Jupyter notebooks with Quarto?
Yes! Quarto can render Jupyter notebooks and you can use Jupyter, JupyterLab or any other .ipynb notebook editor with Quarto. You can render existing .ipynb notebooks as-is with Quarto, but adding Quarto-specific output options or a YAML header can enhance the output. Visit theJupyterLab page for more information.


What programming languages are supported in Quarto?
The principal languages supported by Quarto are Python, R, Julia, and Observable JavaScript. Integration with Jupyter also enables the use of many other languages. 
Each Quarto document can be optionally processed by a computational engine (the engine can be manually specified or automatically detected based on the code chunks within). Current engines include Knitr (which is also used by R Markdown and supports a variety of languages including R, Python, and Julia, etc.) and Jupyter (which supports many languages including Python, Julia, and R). See the documentation on Engine Binding for additional details.


What human languages are supported in Quarto?
You can write your Quarto documentation in your human language of choice. The lang document option is used to identify the main language of the document using IETF language tags (following the BCP 47 standard), such as en or en-GB. 


Can I use Quarto to develop proprietary content?
Yes! The copyright on Quarto does not cover the original content that you generate using Quarto. Using Quarto to create original content does not place any restrictions, legally, on the license that you choose for the original content that you create, nor does it “reach through” to affect software that you might be writing documentation for with Quarto.


But doesn’t the GPL cover exported HTML documents when they include styles or functionalities from Quarto?
It covers the styles or functionalities themselves. It does not cover your original content because your original content is not a derivative work of the Quarto styles or functionalities.


How can I share documents and have people comment on them?
You can publish Quarto content to various locations. See the user guides for publishing for details on using Quarto Pub, GitHub Pages, Netlify, Posit Connect, and other services with Quarto. Once documents are published you can use  hypothes.is, Utterances, or Giscus for commenting. Learn more in the documentation on commenting.


Can I do collaborative editing with Quarto?
There is not yet anything specific for collaborative editing in Quarto. You can collaborate on .qmd files in the same way you currently do for any text or code files. 
Posit Workbench allows for Project Sharing for interactive editing and collaboration on the same document.


Where can I publish Quarto websites?
There are a wide variety of ways to publish Quarto websites. Website content is by default written to the \_site sub-directory (you can customize this using the output-dir option). Publishing is simply a matter of copying the output directory to a web server or web hosting service.
The publishing documentation describes several convenient options for Quarto website deployment including Posit Connect, Netlify, GitHub Pages, Firebase, Site44, and Amazon S3. We’ll mostly defer to the documentation provided by those various services, but will note any Quarto website specific configuration required.


Does Posit Connect support Quarto?
Yes! You can publish Quarto content to Posit Connect v2021.08.0 or later. Quarto has to be enabled as documented in the Posit Connect admin guide. Connect’s user documentation refers to Quarto.org docs on how to publish from the RStudio IDE. To publish Python-based Quarto content, you can use the rsconnect-python CLI from various locations, including VSCode, JupyterLab or the terminal.

Why the name Quarto?
We wanted to use a name that had meaning in the history of publishing and landed on Quarto, which is the format of a book or pamphlet produced from full sheets printed with eight pages of text, four to a side, then folded twice to produce four leaves. The earliest known European printed book is a Quarto, the Sibyllenbuch, believed to have been printed by Johannes Gutenberg in 1452–53.
