+### Front matter
+
+> [Introduced](https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/23331)
+ in GitLab 11.6.
+
+Front matter is metadata included at the beginning of a markdown document, preceding
+its content. This data can be used by static site generators such as [Jekyll](https://jekyllrb.com/docs/front-matter/) and [Hugo](https://gohugo.io/content-management/front-matter/),
+and many other applications.
+
+In GitLab, front matter is only used in Markdown files and wiki pages, not the other places where Markdown formatting is supported.
+When you view a Markdown file rendered by GitLab, any front matter is displayed as-is, in a box at the top of the document, before the rendered HTML content.
+To view an example, you can toggle between the source and rendered version of a [GitLab documentation file](https://gitlab.com/gitlab-org/gitlab-ce/blob/master/doc/README.md).
+
+The following delimeters are supported:
+
+- YAML (`---`):
+
+ ```
+ ---
+ title: About Front Matter
+ example:
+ language: yaml
+ ---
+ ```
+
+- TOML (`+++`):
+
+ ```
+ +++
+ title = "About Front Matter"
+ [example]
+ language = "toml"
+ +++
+ ```
+
+- JSON (`;;;`):
+
+ ```
+ ;;;
+ {
+ "title": "About Front Matter"
+ "example": {
+ "language": "json"
+ }
+ }
+ ;;;
+ ```
+
+Other languages are supported by adding a specifier to any of the existing
+delimiters. For example:
+
+```
+---php
+$title = "About Front Matter";
+$example = array(
+ 'language' => "php",
+);
+---
+```
+
