+
+**Front matter** allows you to keep metadata attached to an instance of a [content type][]---i.e., embedded inside a content file---and is one of the many features that gives Hugo its strength.
+
+{{< youtube Yh2xKRJGff4 >}}
+
+## Front Matter Formats
+
+Hugo supports three formats for front matter, each with their own identifying tokens.
+
+TOML
+: identified by opening and closing `+++`.
+
+YAML
+: identified by opening and closing `---`.
+
+JSON
+: a single JSON object surrounded by '`{`' and '`}`', followed by a new line.
+
+### Example
+
+{{< code-toggle >}}
++++
+title = "spf13-vim 3.0 release and new website"
+description = "spf13-vim is a cross platform distribution of vim plugins and resources for Vim."
+tags = [ ".vimrc", "plugins", "spf13-vim", "vim" ]
+date = "2012-04-06"
+categories = [
+ "Development",
+ "VIM"
+]
+slug = "spf13-vim-3-0-release-and-new-website"
++++
+{{</ code-toggle >}}
+
+## Front Matter Variables
+
+### Predefined
+
+There are a few predefined variables that Hugo is aware of. See [Page Variables][pagevars] for how to call many of these predefined variables in your templates.
+
+aliases
+: an array of one or more aliases (e.g., old published paths of renamed content) that will be created in the output directory structure . See [Aliases][aliases] for details.
+
+date
+: the datetime at which the content was created; note this value is auto-populated according to Hugo's built-in [archetype][].
+
+description
+: the description for the content.
+
+draft
+: if `true`, the content will not be rendered unless the `--buildDrafts` flag is passed to the `hugo` command.
+
+expiryDate
+: the datetime at which the content should no longer be published by Hugo; expired content will not be rendered unless the `--buildExpired` flag is passed to the `hugo` command.
+
+headless
+: if `true`, sets a leaf bundle to be [headless][headless-bundle].
+
+isCJKLanguage
+: if `true`, Hugo will explicitly treat the content as a CJK language; both `.Summary` and `.WordCount` work properly in CJK languages.
+
+keywords
+: the meta keywords for the content.
+
+layout
+: the layout Hugo should select from the [lookup order][lookup] when rendering the content. If a `type` is not specified in the front matter, Hugo will look for the layout of the same name in the layout directory that corresponds with a content's section. See ["Defining a Content Type"][definetype]
+
+lastmod
+: the datetime at which the content was last modified.
+
+linkTitle
+: used for creating links to content; if set, Hugo defaults to using the `linktitle` before the `title`. Hugo can also [order lists of content by `linktitle`][bylinktitle].
+
+markup
+: **experimental**; specify `"rst"` for reStructuredText (requires`rst2html`) or `"md"` (default) for Markdown.
+
+outputs
+: allows you to specify output formats specific to the content. See [output formats][outputs].
+
+publishDate
+: if in the future, content will not be rendered unless the `--buildFuture` flag is passed to `hugo`.
+
+resources
+: used for configuring page bundle resources. See [Page Resources][page-resources].
+
+slug
+: appears as the tail of the output URL. A value specified in front matter will override the segment of the URL based on the filename.
+
+title
+: the title for the content.
+
+type
+: the type of the content; this value will be automatically derived from the directory (i.e., the [section][]) if not specified in front matter.
+
+url
+: the full path to the content from the web root. It makes no assumptions about the path of the content file. It also ignores any language prefixes of
+the multilingual feature.
+
+weight
+: used for [ordering your content in lists][ordering].
+
+\<taxonomies\>
+: field name of the *plural* form of the index. See `tags` and `categories` in the above front matter examples. _Note that the plural form of user-defined taxonomies cannot be the same as any of the predefined front matter variables._
+
+{{% note "Hugo's Default URL Destinations" %}}
+If neither `slug` nor `url` is present and [permalinks are not configured otherwise in your site `config` file](/content-management/urls/#permalinks), Hugo will use the filename of your content to create the output URL. See [Content Organization](/content-management/organization) for an explanation of paths in Hugo and [URL Management](/content-management/urls/) for ways to customize Hugo's default behaviors.
+{{% /note %}}
+
+### User-Defined
+
+You can add fields to your front matter arbitrarily to meet your needs. These user-defined key-values are placed into a single `.Params` variable for use in your templates.
+
+The following fields can be accessed via `.Params.include_toc` and `.Params.show_comments`, respectively. The [Variables][] section provides more information on using Hugo's page- and site-level variables in your templates.
+
+{{< code-toggle copy="false" >}}
+include_toc: true
+show_comments: false
+{{</ code-toggle >}}
+
+
+## Order Content Through Front Matter
+
+You can assign content-specific `weight` in the front matter of your content. These values are especially useful for [ordering][ordering] in list views. You can use `weight` for ordering of content and the convention of [`<TAXONOMY>_weight`][taxweight] for ordering content within a taxonomy. See [Ordering and Grouping Hugo Lists][lists] to see how `weight` can be used to organize your content in list views.
+
+## Override Global Markdown Configuration
+
+It's possible to set some options for Markdown rendering in a content's front matter as an override to the [BlackFriday rendering options set in your project configuration][config].
