-**Markdown is the main content format** and comes in two flavours: The excellent [Blackfriday project][blackfriday] (name your files `*.md` or set `markup = "markdown"` in front matter) or its fork [Mmark][mmark] (name your files `*.mmark` or set `markup = "mmark"` in front matter), both very fast markdown engines written in Go.
+You can put any file type into your `/content` directories, but Hugo uses the `markup` front matter value if set or the file extension (see `Markup identifiers` in the table below) to determine if the markup needs to be processed, e.g.:
-For Emacs users, [go-org](https://github.com/niklasfasching/go-org) provides built-in native support for Org-mode (name your files `*.org` or set `markup = "org"` in front matter)
+* Markdown converted to HTML
+* [Shortcodes](/content-management/shortcodes/) processed
+* Layout applied
-But in many situations, plain HTML is what you want. Just name your files with `.html` or `.htm` extension inside your content folder. Note that if you want your HTML files to have a layout, they need front matter. It can be empty, but it has to be there:
+## List of content formats
-```html

-{{% note "Deeply Nested Lists" %}}-Before you begin writing your content in markdown, Blackfriday has a known issue [(#329)](https://github.com/russross/blackfriday/issues/329) with handling deeply nested lists. Luckily, there is an easy workaround. Use 4-spaces (i.e., <kbd>tab</kbd>) rather than 2-space indentations.
-{{% /note %}}+The `markup identifier` is fetched from either the `markup` variable in front matter or from the file extension. For markup-related configuration, see [Configure Markup](/getting-started/configuration-markup/).
-## Configure BlackFriday Markdown Rendering
-You can configure multiple aspects of Blackfriday as shown in the following list. See the docs on [Configuration][config] for the full list of explicit directions you can give to Hugo when rendering your site.
+## External Helpers
-{{< readfile file="/content/en/readfiles/bfconfig.md" markdown="true" >}}-
-## Extend Markdown
-
-Hugo provides some convenient methods for extending markdown.
-
-### Task Lists
-
-Hugo supports [GitHub-styled task lists (i.e., TODO lists)][gfmtasks] for the Blackfriday markdown renderer. If you do not want to use this feature, you can disable it in your configuration.
-
-#### Example Task List Input
-
-{{< code file="content/my-to-do-list.md" >}}-- [ ] a task list item
-- [ ] list syntax required
-- [ ] incomplete
-- [x] completed
-{{< /code >}}-
-#### Example Task List Output
-
-The preceding markdown produces the following HTML in your rendered website:
-
-```
-<ul class="task-list">
- <li><input type="checkbox" disabled="" class="task-list-item"> a task list item</li>
- <li><input type="checkbox" disabled="" class="task-list-item"> list syntax required</li>
- <li><input type="checkbox" disabled="" class="task-list-item"> incomplete</li>
- <li><input type="checkbox" checked="" disabled="" class="task-list-item"> completed</li>
-</ul>
-```
-
-#### Example Task List Display
-
-The following shows how the example task list will look to the end users of your website. Note that visual styling of lists is up to you. This list has been styled according to [the Hugo Docs stylesheet][hugocss].
-
-- [ ] a task list item
-- [ ] list syntax required
-- [ ] incomplete
-- [x] completed
-
-### Emojis
-
-To add emojis directly to content, set `enableEmoji` to `true` in your [site configuration][config]. To use emojis in templates or shortcodes, see [`emojify` function][].
-
-For a full list of emojis, see the [Emoji cheat sheet][emojis].
-
-### Shortcodes
-
-If you write in Markdown and find yourself frequently embedding your content with raw HTML, Hugo provides built-in shortcodes functionality. This is one of the most powerful features in Hugo and allows you to create your own Markdown extensions very quickly.
-
-See [Shortcodes][sc] for usage, particularly for the built-in shortcodes that ship with Hugo, and [Shortcode Templating][sct] to learn how to build your own.
-
-### Code Blocks
-
-Hugo supports GitHub-flavored markdown's use of triple back ticks, as well as provides a special [`highlight` shortcode][hlsc], and syntax highlights those code blocks natively using *Chroma*. Users also have an option to use *Pygments* instead. See the [Syntax Highlighting][hl] section for details.
-
-## Mmark
-
-Mmark is a [fork of BlackFriday][mmark] and markdown superset that is well suited for writing [IETF documentation][ietf]. You can see examples of the syntax in the [Mmark GitHub repository][mmark] or the full syntax on [Miek Gieben's website][].
-
-### Use Mmark
-
-As Hugo ships with Mmark, using the syntax is as easy as changing the extension of your content files from `.md` to `.mmark`.
-
-In the event that you want to only use Mmark in specific files, you can also define the Mmark syntax in your content's front matter:
-
-```
----
-title: My Post
-date: 2017-04-01
-markup: mmark
----
-```
-
-{{% warning %}}-Thare are some features not available in Mmark; one example being that shortcodes are not translated when used in an included `.mmark` file ([#3131](https://github.com/gohugoio/hugo/issues/3137)), and `EXTENSION_ABBREVIATION` ([#1970](https://github.com/gohugoio/hugo/issues/1970)) and the aforementioned GFM todo lists ([#2270](https://github.com/gohugoio/hugo/issues/2270)) are not fully supported. Contributions are welcome.

-## MathJax with Hugo
-
-[MathJax](https://www.mathjax.org/) is a JavaScript library that allows the display of mathematical expressions described via a LaTeX-style syntax in the HTML (or Markdown) source of a web page. As it is a pure a JavaScript library, getting it to work within Hugo is fairly straightforward, but does have some oddities that will be discussed here.
-
-This is not an introduction into actually using MathJax to render typeset mathematics on your website. Instead, this page is a collection of tips and hints for one way to get MathJax working on a website built with Hugo.
-
-### Enable MathJax
-
-The first step is to enable MathJax on pages that you would like to have typeset math. There are multiple ways to do this (adventurous readers can consult the [Loading and Configuring](https://docs.mathjax.org/en/latest/web/configuration.html) section of the MathJax documentation for additional methods of including MathJax), but the easiest way is to use the secure MathJax CDN by include a `<script>` tag for the officially recommended secure CDN ([cdn.js.com](https://cdnjs.com)):
-
-{{< code file="add-mathjax-to-page.html" >}}-<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.1/MathJax.js?config=TeX-AMS-MML_HTMLorMML">
-</script>
-{{< /code >}}-
-One way to ensure that this code is included in all pages is to put it in one of the templates that live in the `layouts/partials/` directory. For example, I have included this in the bottom of my template `footer.html` because I know that the footer will be included in every page of my website.
-
-### Options and Features
-
-MathJax is a stable open-source library with many features. I encourage the interested reader to view the [MathJax Documentation](https://docs.mathjax.org/en/latest/index.html), specifically the sections on [Basic Usage](http://docs.mathjax.org/en/latest/index.html#basic-usage) and [MathJax Configuration Options](http://docs.mathjax.org/en/latest/index.html#mathjax-configuration-options).
-
-### Issues with Markdown
-
-{{% note %}}-The following issues with Markdown assume you are using `.md` for content and BlackFriday for parsing. Using [Mmark](#mmark) as your content format will obviate the need for the following workarounds.
-
-When using Mmark with MathJax, use `displayMath: [['$$','$$'], ['\\[','\\]']]`. See the [Mmark `README.md`](https://github.com/miekg/mmark/wiki/Syntax#math-blocks) for more information. In addition to MathJax, Mmark has been shown to work well with [KaTeX](https://github.com/Khan/KaTeX). See this [related blog post from a Hugo user](http://nosubstance.me/post/a-great-toolset-for-static-blogging/).
-{{% /note %}}-
-After enabling MathJax, any math entered between proper markers (see the [MathJax documentation][mathjaxdocs]) will be processed and typeset in the web page. One issue that comes up, however, with Markdown is that the underscore character (`_`) is interpreted by Markdown as a way to wrap text in `emph` blocks while LaTeX (MathJax) interprets the underscore as a way to create a subscript. This "double speak" of the underscore can result in some unexpected and unwanted behavior.
-
-### Solution
-
-There are multiple ways to remedy this problem. One solution is to simply escape each underscore in your math code by entering `\_` instead of `_`. This can become quite tedious if the equations you are entering are full of subscripts.
-
-Another option is to tell Markdown to treat the MathJax code as verbatim code and not process it. One way to do this is to wrap the math expression inside a `<div>` `</div>` block. Markdown would ignore these sections and they would get passed directly on to MathJax and processed correctly. This works great for display style mathematics, but for inline math expressions the line break induced by the `<div>` is not acceptable. The syntax for instructing Markdown to treat inline text as verbatim is by wrapping it in backticks (`` ` ``). You might have noticed, however, that the text included in between backticks is rendered differently than standard text (on this site these are items highlighted in red). To get around this problem, we could create a new CSS entry that would apply standard styling to all inline verbatim text that includes MathJax code. Below I will show the HTML and CSS source that would accomplish this (note this solution was adapted from [this blog post](http://doswa.com/2011/07/20/mathjax-in-markdown.html)---all credit goes to the original author).
-
-{{< code file="mathjax-markdown-solution.html" >}}-<script type="text/x-mathjax-config">
-MathJax.Hub.Config({- tex2jax: {- inlineMath: [['$','$'], ['\\(','\\)']],- displayMath: [['$$','$$'], ['\[','\]']],
- processEscapes: true,
- processEnvironments: true,
- skipTags: ['script', 'noscript', 'style', 'textarea', 'pre'],
- TeX: { equationNumbers: { autoNumber: "AMS" },- extensions: ["AMSmath.js", "AMSsymbols.js"] }
- }
-});
-</script>
-{{< /code >}}-
-As before, this content should be included in the HTML source of each page that will be using MathJax. The next code snippet contains the CSS that is used to have verbatim MathJax blocks render with the same font style as the body of the page.
-
-{{< code file="mathjax-style.css" >}}-code.has-jax {- font: inherit;
- font-size: 100%;
- background: inherit;
- border: inherit;
- color: #515151;
-}
-{{< /code >}}-
-In the CSS snippet, notice the line `color: #515151;`. `#515151` is the value assigned to the `color` attribute of the `body` class in my CSS. In order for the equations to fit in with the body of a web page, this value should be the same as the color of the body.
-
-### Usage
-
-With this setup, everything is in place for a natural usage of MathJax on pages generated using Hugo. In order to include inline mathematics, just put LaTeX code in between `` `$ TeX Code $` `` or `` `\( TeX Code \)` ``. To include display style mathematics, just put LaTeX code in between `<div>$$TeX Code$$</div>`. All the math will be properly typeset and displayed within your Hugo generated web page!
-
-## Additional Formats Through External Helpers
-
-Hugo has a new concept called _external helpers_. It means that you can write your content using [Asciidoc][ascii], [reStructuredText][rest], or [pandoc]. If you have files with associated extensions, Hugo will call external commands to generate the content. ([See the Hugo source code for external helpers][helperssource].)
-
-For example, for Asciidoc files, Hugo will try to call the `asciidoctor` or `asciidoc` command. This means that you will have to install the associated tool on your machine to be able to use these formats. ([See the Asciidoctor docs for installation instructions](https://asciidoctor.org/docs/install-toolchain/)).
-
-To use these formats, just use the standard extension and the front matter exactly as you would do with natively supported `.md` files.
+Some of the formats in the table above needs external helpers installed on your PC. For example, for Asciidoc files, Hugo will try to call the `asciidoctor` or `asciidoc` command. This means that you will have to install the associated tool on your machine to be able to use these formats. ([See the Asciidoctor docs for installation instructions](https://asciidoctor.org/docs/install-toolchain/)).
Hugo passes reasonable default arguments to these external helpers by default:

+## Configure Markup
+
+{{< new-in "0.60.0" >}}+
+See [Goldmark](#goldmark) for settings related to the default Markdown handler in Hugo.
+
+Below are all markup related configuration in Hugo with their default settings:
+
+{{< code-toggle config="markup" />}}+
+**See each section below for details.**
+
+### Goldmark
+
+[Goldmark](https://github.com/yuin/goldmark/) is from Hugo 0.60 the default library used for Markdown. It's fast, it's [CommonMark](https://spec.commonmark.org/0.29/) compliant and it's very flexible. Note that the feature set of Goldmark vs Blackfriday isn't the same; you gain a lot but also lose some, but we will work to bridge any gap in the upcoming Hugo versions.
+
+This is the default configuration:
+
+{{< code-toggle config="markup.goldmark" />}}+
+Some settings explained:
+
+unsafe
+: By default, Goldmark does not render raw HTMLs and potentially dangerous links. If you have lots of inline HTML and/or JavaScript, you may need to turn this on.
+
+typographer
+: This extension substitutes punctuations with typographic entities like [smartypants](https://daringfireball.net/projects/smartypants/).
+
+### Blackfriday
+
+
+[Blackfriday](https://github.com/russross/blackfriday) was Hugo's default Markdown rendering engine, now replaced with Goldmark. But you can still use it: Just set `defaultMarkdownHandler` to `blackfriday` in your top level `markup` config.
+
+This is the default config:
+
+{{< code-toggle config="markup.blackFriday" />}}+
+### Highlight
+
+This is the default `highlight` configuration. Note that some of these settings can be set per code block, see [Syntax Highlighting](/content-management/syntax-highlighting/).
+
+{{< code-toggle config="markup.highlight" />}}+
+For `style`, see these galleries:
+
+* [Short snippets](https://xyproto.github.io/splash/docs/all.html)
+* [Long snippets](https://xyproto.github.io/splash/docs/longer/all.html)
+
+For CSS, see [Generate Syntax Highlighter CSS](/content-management/syntax-highlighting/#generate-syntax-highlighter-css).
+
+### Table Of Contents
+
+{{< code-toggle config="markup.tableOfContents" />}}+
+These settings only works for the Goldmark renderer:
+
+startLevel
+: The heading level, values starting at 1 (`h1`), to start render the table of contents.
+
+endLevel
+: The heading level, inclusive, to stop render the table of contents.

-## Configure Blackfriday
-
-[Blackfriday](https://github.com/russross/blackfriday) is Hugo's built-in Markdown rendering engine.
-
-Hugo typically configures Blackfriday with sane default values that should fit most use cases reasonably well.
-
-However, if you have specific needs with respect to Markdown, Hugo exposes some of its Blackfriday behavior options for you to alter. The following table lists these Hugo options, paired with the corresponding flags from Blackfriday's source code ( [html.go](https://github.com/russross/blackfriday/blob/master/html.go) and [markdown.go](https://github.com/russross/blackfriday/blob/master/markdown.go)).
-
-{{< readfile file="/content/en/readfiles/bfconfig.md" markdown="true" >}}-
-{{% note %}}-1. Blackfriday flags are *case sensitive* as of Hugo v0.15.
-2. Blackfriday flags must be grouped under the `blackfriday` key and can be set on both the site level *and* the page level. Any setting on a page will override its respective site setting.

Upgrading Hugo is as easy as downloading and replacing the executable you’ve placed in your `PATH` or run `brew upgrade hugo` if using Homebrew.
-## Install Pygments (Optional)
-
-The Hugo executable has one *optional* external dependency for source code highlighting ([Pygments][pygments]).
-
-If you want to have source code highlighting using the [highlight shortcode][], you need to install the Python-based Pygments program. The procedure is outlined on the [Pygments homepage][pygments].
-
## Next Steps
Now that you've installed Hugo, read the [Quick Start guide][quickstart] and explore the rest of the documentation. If you have questions, ask the Hugo community directly by visiting the [Hugo Discussion Forum][forum].

-## Blackfriday Options
-
-`taskLists`
-: default: **`true`**<br>
- Blackfriday flag: <br>
- Purpose: `false` turns off GitHub-style automatic task/TODO list generation.
-
-`smartypants`
-: default: **`true`** <br>
- Blackfriday flag: **`HTML_USE_SMARTYPANTS`** <br>
- Purpose: `false` disables smart punctuation substitutions, including smart quotes, smart dashes, smart fractions, etc. If `true`, it may be fine-tuned with the `angledQuotes`, `fractions`, `smartDashes`, and `latexDashes` flags (see below).
-
-`smartypantsQuotesNBSP`
-: default: **`false`** <br>
- Blackfriday flag: **`HTML_SMARTYPANTS_QUOTES_NBSP`** <br>
- Purpose: `true` enables French style Guillemets with non-breaking space inside the quotes.
-
-`angledQuotes`
-: default: **`false`**<br>
- Blackfriday flag: **`HTML_SMARTYPANTS_ANGLED_QUOTES`**<br>
- Purpose: `true` enables smart, angled double quotes. Example: "Hugo" renders to «Hugo» instead of “Hugo”.
-
-`fractions`
-: default: **`true`**<br>
- Blackfriday flag: **`HTML_SMARTYPANTS_FRACTIONS`** <br>
- Purpose: <code>false</code> disables smart fractions.<br>
- Example: `5/12` renders to <sup>5</sup>⁄<sub>12</sub>(<code><sup>5</sup>&frasl;<sub>12</sub></code>).<br> <small><strong>Caveat:</strong> Even with <code>fractions = false</code>, Blackfriday still converts `1/2`, `1/4`, and `3/4` respectively to ½ (<code>&frac12;</code>), ¼ (<code>&frac14;</code>) and ¾ (<code>&frac34;</code>), but only these three.</small>
-
-`smartDashes`
-: default: **`true`** <br>
- Blackfriday flag: **`HTML_SMARTY_DASHES`** <br>
- Purpose: `false` disables smart dashes; i.e., the conversion of multiple hyphens into an en-dash or em-dash. If `true`, its behavior can be modified with the `latexDashes` flag below.
-
-`latexDashes`
-: default: **`true`** <br>
- Blackfriday flag: **`HTML_SMARTYPANTS_LATEX_DASHES`** <br>
- Purpose: `false` disables LaTeX-style smart dashes and selects conventional smart dashes. Assuming `smartDashes`: <br>
- If `true`, `--` is translated into – (`–`), whereas `---` is translated into — (`—`). <br>
- However, *spaced* single hyphen between two words is translated into an en dash— e.g., "`12 June - 3 July`" becomes `12 June – 3 July` upon rendering.
-
-`hrefTargetBlank`
-: default: **`false`** <br>
- Blackfriday flag: **`HTML_HREF_TARGET_BLANK`** <br>
- Purpose: `true` opens <s>external links</s> **absolute** links in a new window or tab. While the `target="_blank"` attribute is typically used for external links, Blackfriday does that for _all_ absolute links ([ref](https://discourse.gohugo.io/t/internal-links-in-same-tab-external-links-in-new-tab/11048/8)). One needs to make note of this if they use absolute links throughout, for internal links too (for example, by setting `canonifyURLs` to `true` or via `absURL`).
-
-`nofollowLinks`
-: default: **`false`** <br>
- Blackfriday flag: **`HTML_NOFOLLOW_LINKS`** <br>
- Purpose: `true` creates <s>external links</s> **absolute** links with `nofollow` being added to their `rel` attribute. Thereby crawlers are advised to not follow the link. While the `rel="nofollow"` attribute is typically used for external links, Blackfriday does that for _all_ absolute links. One needs to make note of this if they use absolute links throughout, for internal links too (for example, by setting `canonifyURLs` to `true` or via `absURL`).
-
-`noreferrerLinks`
-: default: **`false`** <br>
- Blackfriday flag: **`HTML_NOREFERRER_LINKS`** <br>
- Purpose: `true` creates <s>external links</s> **absolute** links with `noreferrer` being added to their `rel` attribute. Thus when following the link no referrer information will be leaked. While the `rel="noreferrer"` attribute is typically used for external links, Blackfriday does that for _all_ absolute links. One needs to make note of this if they use absolute links throughout, for internal links too (for example, by setting `canonifyURLs` to `true` or via `absURL`).
-
-`plainIDAnchors`
-: default **`true`** <br>
- Blackfriday flag: **`FootnoteAnchorPrefix` and `HeaderIDSuffix`** <br>
- Purpose: `true` renders any heading and footnote IDs without the document ID. <br>
- Example: renders `#my-heading` instead of `#my-heading:bec3ed8ba720b970`
-
-`extensions`
-: default: **`[]`** <br>
- Purpose: Enable one or more Blackfriday's Markdown extensions (**`EXTENSION_*`**). <br>
- Example: Include `hardLineBreak` in the list to enable Blackfriday's `EXTENSION_HARD_LINE_BREAK`. <br>
- *See [Blackfriday extensions](#blackfriday-extensions) section for information on all extensions.*
-
-`extensionsmask`
-: default: **`[]`** <br>
- Purpose: Disable one or more of Blackfriday's Markdown extensions (**`EXTENSION_*`**). <br>
- Example: Include `autoHeaderIds` as `false` in the list to disable Blackfriday's `EXTENSION_AUTO_HEADER_IDS`. <br>
- *See [Blackfriday extensions](#blackfriday-extensions) section for information on all extensions.*
-
-`skipHTML`
-: default: **`false`** <br>
- Blackfriday flag: **`HTML_SKIP_HTML`** <br>
- Purpose: `true` causes any HTML in the markdown files to be skipped.
-
-## Blackfriday extensions
-
-`noIntraEmphasis`
-: default: *enabled* <br>
- Purpose: The "\_" character is commonly used inside words when discussing
- code, so having Markdown interpret it as an emphasis command is usually the
- wrong thing. When enabled, Blackfriday lets you treat all emphasis markers
- as normal characters when they occur inside a word.
-
-`tables`
-: default: *enabled* <br>
- Purpose: When enabled, tables can be created by drawing them in the input
- using the below syntax:
- Example:
-
- Name | Age
- --------|------
- Bob | 27
- Alice | 23
-
-`fencedCode`
-: default: *enabled* <br>
- Purpose: When enabled, in addition to the normal 4-space indentation to mark
- code blocks, you can explicitly mark them and supply a language (to make
- syntax highlighting simple).
-
- You can use 3 or more backticks to mark the beginning of the block, and the
- same number to mark the end of the block.
-
- Example:
-
- ```md
- # Heading Level 1
- Some test
- ## Heading Level 2
- Some more test
- ```
-
-`autolink`
-: default: *enabled* <br>
- Purpose: When enabled, URLs that have not been explicitly marked as links
- will be converted into links.
-
-`strikethrough`
-: default: *enabled* <br>
- Purpose: When enabled, text wrapped with two tildes will be crossed out. <br>
- Example: `~~crossed-out~~`
-
-`laxHtmlBlocks`
-: default: *disabled* <br>
- Purpose: When enabled, loosen up HTML block parsing rules.
-
-`spaceHeaders`
-: default: *enabled* <br>
- Purpose: When enabled, be strict about prefix header rules.
-
-`hardLineBreak`
-: default: *disabled* <br>
- Purpose: When enabled, newlines in the input translate into line breaks in
- the output.
-
-
-`tabSizeEight`
-: default: *disabled* <br>
- Purpose: When enabled, expand tabs to eight spaces instead of four.
-
-`footnotes`
-: default: *enabled* <br>
- Purpose: When enabled, Pandoc-style footnotes will be supported. The
- footnote marker in the text that will become a superscript text; the
- footnote definition will be placed in a list of footnotes at the end of the
- document. <br>
- Example:
-
- This is a footnote.[^1]
-
- [^1]: the footnote text.
-
-`noEmptyLineBeforeBlock`
-: default: *disabled* <br>
- Purpose: When enabled, no need to insert an empty line to start a (code,
- quote, ordered list, unordered list) block.
-
-
-`headerIds`
-: default: *enabled* <br>
- Purpose: When enabled, allow specifying header IDs with `{#id}`.-
-`titleblock`
-: default: *disabled* <br>
- Purpose: When enabled, support [Pandoc-style title blocks][1].
-
-`autoHeaderIds`
-: default: *enabled* <br>
- Purpose: When enabled, auto-create the header ID's from the headline text.
-
-`backslashLineBreak`
-: default: *enabled* <br>
- Purpose: When enabled, translate trailing backslashes into line breaks.
-
-`definitionLists`
-: default: *enabled* <br>
- Purpose: When enabled, a simple definition list is made of a single-line
- term followed by a colon and the definition for that term. <br>
- Example:
-
- Cat
- : Fluffy animal everyone likes
-
- Internet
- : Vector of transmission for pictures of cats
-
- Terms must be separated from the previous definition by a blank line.
-
-`joinLines`
-: default: *enabled* <br>
- Purpose: When enabled, delete newlines and join the lines.
