[John Gruber](https://en.wikipedia.org/wiki/John_Gruber "John Gruber") created Markdown in 2004 as an easy-to-read [markup language](https://en.wikipedia.org/wiki/Markup_language "Markup language").[\[9\]](#cite_note-philosophy-9) Markdown is widely used for [blogging](https://en.wikipedia.org/wiki/Blog "Blog"), [instant messaging](https://en.wikipedia.org/wiki/Instant_messaging "Instant messaging"), and [large language models](https://en.wikipedia.org/wiki/Large_language_models "Large language models"),[\[10\]](#cite_note-llm-markdown-10) and also used elsewhere in [online forums](https://en.wikipedia.org/wiki/Online_forums "Online forums"), [collaborative software](https://en.wikipedia.org/wiki/Collaborative_software "Collaborative software"), [note-taking software](https://en.wikipedia.org/wiki/Note-taking_software "Note-taking software"), [documentation](https://en.wikipedia.org/wiki/Documentation "Documentation") pages, and [README files](https://en.wikipedia.org/wiki/README "README").

The initial description of Markdown[\[11\]](#cite_note-11) contained ambiguities and raised unanswered questions, causing implementations to both intentionally and accidentally diverge from the original version. This was addressed in 2014 when long-standing Markdown contributors released [CommonMark](#CommonMark), an unambiguous specification and test suite for Markdown.[\[12\]](#cite_note-FutureOfMarkdown-12)

## History

\[[edit](/w/index.php?title=Markdown&action=edit&section=1 "Edit section: History")\]

Markdown was inspired by pre-existing [conventions](https://en.wikipedia.org/wiki/Convention_\(norm\) "Convention (norm)") for marking up [plain text](https://en.wikipedia.org/wiki/Plain_text "Plain text") in [email](https://en.wikipedia.org/wiki/Email "Email") and [usenet](https://en.wikipedia.org/wiki/Usenet "Usenet") posts,[\[13\]](#cite_note-ArsTechnica2014-13) such as the earlier markup languages [setext](https://en.wikipedia.org/wiki/Setext "Setext") (c. 1992), [Textile](https://en.wikipedia.org/wiki/Textile_\(markup_language\) "Textile (markup language)") (c. 2002), and [reStructuredText](https://en.wikipedia.org/wiki/ReStructuredText "ReStructuredText") (c. 2002).[\[9\]](#cite_note-philosophy-9)

In 2002, [Aaron Swartz](https://en.wikipedia.org/wiki/Aaron_Swartz "Aaron Swartz") created [atx](https://en.wikipedia.org/wiki/Atx_\(markup_language\) "Atx (markup language)") and referred to it as "the true structured text format". Gruber created the Markdown language in 2004 with Swartz as his "sounding board".[\[14\]](#cite_note-Gruber-14) The goal of the language was to enable people "to write using an easy-to-read and easy-to-write plain text format, optionally convert it to structurally valid [XHTML](https://en.wikipedia.org/wiki/XHTML "XHTML") (or [HTML](https://en.wikipedia.org/wiki/HTML "HTML"))".[\[5\]](#cite_note-md-5)

Another key design goal was *readability*, that the language be readable as-is, without looking like it has been marked up with tags or formatting instructions,[\[9\]](#cite_note-philosophy-9) unlike text formatted with "heavier" [markup languages](https://en.wikipedia.org/wiki/Markup_language "Markup language"), such as [Rich Text Format](https://en.wikipedia.org/wiki/Rich_Text_Format "Rich Text Format") (RTF), HTML, or even [wikitext](https://en.wikipedia.org/wiki/Wikitext "Wikitext"), each of which have obvious in-line tags and formatting instructions which can make the text more difficult for humans to read.

\[*[citation needed](https://en.wikipedia.org/wiki/Wikipedia:Citation_needed "Wikipedia:Citation needed")*\]

Gruber wrote a [Perl](https://en.wikipedia.org/wiki/Perl "Perl") script, `Markdown.pl`, which converts marked-up text input to valid, [well-formed](https://en.wikipedia.org/wiki/Well-formed_document "Well-formed document") XHTML or HTML, encoding angle brackets (`<`, `>`) and [ampersands](https://en.wikipedia.org/wiki/Ampersand "Ampersand") (`&`), which would be misinterpreted as special characters in those languages. It can take the role of a standalone script, a plugin for [Blosxom](https://en.wikipedia.org/wiki/Blosxom "Blosxom") or [Movable Type](https://en.wikipedia.org/wiki/Movable_Type "Movable Type"), or of a text filter for [BBEdit](https://en.wikipedia.org/wiki/BBEdit "BBEdit").[\[5\]](#cite_note-md-5)

## Rise and divergence

\[[edit](/w/index.php?title=Markdown&action=edit&section=2 "Edit section: Rise and divergence")\]

As Markdown's popularity grew rapidly, many Markdown [implementations](https://en.wikipedia.org/wiki/Implementation "Implementation") appeared, driven mostly by the need for additional features such as [tables](https://en.wikipedia.org/wiki/Table_\(information\) "Table (information)"), [footnotes](https://en.wikipedia.org/wiki/Note_\(typography\) "Note (typography)"), definition lists,[\[note 1\]](#cite_note-17) and Markdown inside HTML blocks.

\[*[citation needed](https://en.wikipedia.org/wiki/Wikipedia:Citation_needed "Wikipedia:Citation needed")*\]

The behavior of some of these diverged from the reference implementation, as Markdown was only characterised by an informal [specification](https://en.wikipedia.org/wiki/Specification_\(technical_standard\) "Specification (technical standard)")[\[17\]](#cite_note-18) and a [Perl](https://en.wikipedia.org/wiki/Perl "Perl") implementation for conversion to HTML.

\[*[citation needed](https://en.wikipedia.org/wiki/Wikipedia:Citation_needed "Wikipedia:Citation needed")*\]

At the same time, a number of ambiguities in the informal specification had attracted attention.[\[18\]](#cite_note-gfm_on_github-why_spec-19) These issues spurred the creation of tools such as Babelmark[\[19\]](#cite_note-babelmark-2-20)[\[20\]](#cite_note-babelmark-3-21) to compare the output of various implementations,[\[21\]](#cite_note-22) and an effort by some developers of Markdown [parsers](https://en.wikipedia.org/wiki/Parsing "Parsing") for standardization. However, Gruber has argued that complete standardization would be a mistake: "Different sites (and people) have different needs. No one syntax would make all happy."[\[22\]](#cite_note-23)

Gruber avoided using curly braces in Markdown to unofficially reserve them for implementation-specific extensions.[\[23\]](#cite_note-curlyBraces-24)

### Standardization

\[[edit](/w/index.php?title=Markdown&action=edit&section=4 "Edit section: Standardization")\]

In 2012, a group of people, including [Jeff Atwood](https://en.wikipedia.org/wiki/Jeff_Atwood "Jeff Atwood") and [John MacFarlane](https://en.wikipedia.org/wiki/John_MacFarlane_\(philosopher\) "John MacFarlane (philosopher)"), launched what Atwood characterised as a standardization effort.[\[12\]](#cite_note-FutureOfMarkdown-12)

A community website now aims to "document various tools and resources available to document authors and developers, as well as implementors of the various Markdown implementations".[\[26\]](#cite_note-27)

### Name

\[[edit](/w/index.php?title=Markdown&action=edit&section=5 "Edit section: Name")\]

In September 2014, Gruber objected to the usage of "Markdown" in the name of this effort and it was rebranded as "CommonMark".[\[13\]](#cite_note-ArsTechnica2014-13)[\[27\]](#cite_note-28)[\[28\]](#cite_note-29) CommonMark.org published several versions of a specification, reference implementation, test suite, and "\[plans\] to announce a finalized 1.0 spec and test suite in 2019".[\[29\]](#cite_note-commonmark.org-30) A finalized 1.0 spec has not been released, as major issues still remain unsolved.[\[30\]](#cite_note-31)

### Adoption

\[[edit](/w/index.php?title=Markdown&action=edit&section=6 "Edit section: Adoption")\]

Nonetheless, several websites and projects have adopted CommonMark, including [Codeberg](https://en.wikipedia.org/wiki/Codeberg "Codeberg"), [Discourse](https://en.wikipedia.org/wiki/Discourse_\(software\) "Discourse (software)"), [GitHub](https://en.wikipedia.org/wiki/GitHub "GitHub"), [GitLab](https://en.wikipedia.org/wiki/GitLab "GitLab"), [Reddit](https://en.wikipedia.org/wiki/Reddit "Reddit"), [Qt](https://en.wikipedia.org/wiki/Qt_\(software\) "Qt (software)"), [Stack Exchange](https://en.wikipedia.org/wiki/Stack_Exchange "Stack Exchange") ([Stack Overflow](https://en.wikipedia.org/wiki/Stack_Overflow "Stack Overflow")), and [Swift](https://en.wikipedia.org/wiki/Swift_\(programming_language\) "Swift (programming language)").

In March 2016, two relevant informational Internet [RFCs](https://en.wikipedia.org/wiki/Request_for_Comments "Request for Comments") were published:

*   RFC [7763](https://www.rfc-editor.org/rfc/rfc7763) – "The text/markdown Media Type,"[\[2\]](#cite_note-rfc7763-2) *Informational.*

    Introduces [MIME](https://en.wikipedia.org/wiki/MIME "MIME") type `text/markdown`.

*   RFC [7764](https://www.rfc-editor.org/rfc/rfc7764) – "Guidance on Markdown: Design Philosophies, Stability Strategies, and Select Registrations,"[\[7\]](#cite_note-rfc7764-7) *Informational.*

    Discusses and registers the variants [MultiMarkdown](https://en.wikipedia.org/wiki/MultiMarkdown "MultiMarkdown"), [GitHub Flavored Markdown](#GFM) (GFM), [Pandoc](https://en.wikipedia.org/wiki/Pandoc "Pandoc"), and Markdown Extra (among others).[\[31\]](#cite_note-IANA-32)

## Variants

\[[edit](/w/index.php?title=Markdown&action=edit&section=7 "Edit section: Variants")\]

Websites including [Bitbucket](https://en.wikipedia.org/wiki/Bitbucket "Bitbucket"), [Diaspora](https://en.wikipedia.org/wiki/Diaspora_\(social_network\) "Diaspora (social network)"), [Discord](https://en.wikipedia.org/wiki/Discord "Discord"),[\[32\]](#cite_note-33) [GitHub](#GFM),[\[33\]](#cite_note-gfm_on_github-34) [OpenStreetMap](https://en.wikipedia.org/wiki/OpenStreetMap "OpenStreetMap"), [Reddit](https://en.wikipedia.org/wiki/Reddit "Reddit"),[\[34\]](#cite_note-35) [SourceForge](https://en.wikipedia.org/wiki/SourceForge "SourceForge")[\[35\]](#cite_note-36) and [Stack Exchange](https://en.wikipedia.org/wiki/Stack_Exchange "Stack Exchange")[\[36\]](#cite_note-37) use variants of Markdown to make discussions between users easier.

Depending on implementation, basic inline [HTML tags](https://en.wikipedia.org/wiki/HTML_tag "HTML tag") may be supported.[\[37\]](#cite_note-38)

Italic text may be implemented by `_underscores_` or `*single-asterisks*`.[\[38\]](#cite_note-italic-39)

Many platforms implement spoiler formatting that hides text until hovered, clicked or tapped. The most common markup is ||spoiler|| used by Discord[\[39\]](#cite_note-40), Telegram[\[40\]](#cite_note-41)[\[41\]](#cite_note-42), various Matrix clients[\[42\]](#cite_note-43), now defunct Guilded[\[43\]](#cite_note-44), a forum called Flarum[\[44\]](#cite_note-45), a NodeBB plugin[\[45\]](#cite_note-46), the imageboard engine JSChan[\[46\]](#cite_note-47) and possibly more.

### GitHub Flavored Markdown

\[[edit](/w/index.php?title=Markdown&action=edit&section=8 "Edit section: GitHub Flavored Markdown")\]

[GitHub](https://en.wikipedia.org/wiki/GitHub "GitHub") had been using its own variant of Markdown since as early as 2009,[\[47\]](#cite_note-48) which added support for additional formatting such as tables and nesting [block content](https://en.wikipedia.org/wiki/HTML_element#Block_elements "HTML element") inside list elements, as well as GitHub-specific features such as auto-linking references to commits, issues, usernames, etc.

In 2017, GitHub released a formal specification of its [GitHub Flavored Markdown](https://github.github.com/gfm/) (GFM) that is based on [CommonMark](https://en.wikipedia.org/wiki/CommonMark "CommonMark").[\[33\]](#cite_note-gfm_on_github-34) It is a [strict superset](https://en.wikipedia.org/wiki/Superset "Superset") of CommonMark, following its specification exactly except for tables, [strikethrough](https://en.wikipedia.org/wiki/Strikethrough "Strikethrough"), [autolinks](https://en.wikipedia.org/wiki/Automatic_hyperlinking "Automatic hyperlinking") and task lists, which GFM adds as extensions.[\[48\]](#cite_note-49)

Accordingly, GitHub also changed the parser used on their sites, which required that some documents be changed. For instance, GFM now requires that the [hash symbol](https://en.wikipedia.org/wiki/Number_sign "Number sign") that creates a heading be separated from the heading text by a space character.

### Markdown Extra

\[[edit](/w/index.php?title=Markdown&action=edit&section=9 "Edit section: Markdown Extra")\]

Markdown Extra is a [lightweight markup language](https://en.wikipedia.org/wiki/Lightweight_markup_language "Lightweight markup language") based on Markdown implemented in [PHP](https://en.wikipedia.org/wiki/PHP "PHP") (originally), [Python](https://en.wikipedia.org/wiki/Python_\(programming_language\) "Python (programming language)") and [Ruby](https://en.wikipedia.org/wiki/Ruby_\(programming_language\) "Ruby (programming language)").[\[49\]](#cite_note-fortin-2018-50) It adds the following features that are not available with regular Markdown:

*   Markdown markup inside [HTML](https://en.wikipedia.org/wiki/HTML "HTML") blocks
*   Elements with id/class attribute
*   "Fenced code blocks" that span multiple lines of code
*   Tables[\[49\]](#cite_note-fortin-2018-50)
*   Definition lists
*   Footnotes
*   Abbreviations

Markdown Extra is supported in some [content management systems](https://en.wikipedia.org/wiki/Content_management_system "Content management system") such as [Drupal](https://en.wikipedia.org/wiki/Drupal "Drupal"),[\[50\]](#cite_note-51) [Grav (CMS)](https://en.wikipedia.org/wiki/Grav_\(CMS\) "Grav (CMS)"), [Textpattern CMS](https://en.wikipedia.org/wiki/Textpattern "Textpattern")[\[51\]](#cite_note-52) and [TYPO3](https://en.wikipedia.org/wiki/TYPO3 "TYPO3").[\[52\]](#cite_note-53)

## Implementations

\[[edit](/w/index.php?title=Markdown&action=edit&section=11 "Edit section: Implementations")\]

Implementations of Markdown are available for over a dozen [programming languages](https://en.wikipedia.org/wiki/Programming_language "Programming language"); in addition, many [applications](https://en.wikipedia.org/wiki/Application_software "Application software"), platforms and [frameworks](https://en.wikipedia.org/wiki/Software_framework "Software framework") support Markdown.[\[53\]](#cite_note-54) For example, Markdown [plugins](https://en.wikipedia.org/wiki/Plug-in_\(computing\) "Plug-in (computing)") exist for every major [blogging](https://en.wikipedia.org/wiki/Blog "Blog") platform.[\[13\]](#cite_note-ArsTechnica2014-13)

While Markdown is a minimal markup language and is read and edited with a normal [text editor](https://en.wikipedia.org/wiki/Text_editor "Text editor"), there are specially designed editors that preview the files with styles, which are available for all major platforms. Many general-purpose text and [code editors](https://en.wikipedia.org/wiki/Source-code_editor "Source-code editor") have [syntax highlighting](https://en.wikipedia.org/wiki/Syntax_highlighting "Syntax highlighting") plugins for Markdown built into them or available as optional download.

Editors may feature a side-by-side preview window or render the code directly in a [WYSIWYG](https://en.wikipedia.org/wiki/WYSIWYG "WYSIWYG") fashion. Some Markdown editors display an inline preview as users edit Markdown source. Popular examples include [Typora](https://typora.io/), [Obsidian](https://obsidian.md/), and [Marble](https://marble.md/).

I love their syntax extensions — very true to the spirit of Markdown. They use curly braces for their extensions; I'm not sure I ever made this clear, publicly, but I avoided using curly braces in Markdown itself — even though they are very tempting characters — to unofficially reserve them for implementation-specific extensions. Markdoc's extensive use of curly braces for its syntax is exactly the sort of thing I was thinking about.
