YAML Frontmatter is an authoring convention popularized by Jekyll that provides a way to add metadata to pages. It is a block of key-value content that lives at the top of every Markdown file.
The following frontmatter values have special meanings and requirements for this site.
There's also a schema that's used by the test suite to validate every page's frontmatter.
See lib/frontmatter.js
.
- Purpose: Indicates the versions to which a page applies. See Versioning for more info.
- Type:
Object
. Allowable keys map to product names and can be found in theversions
object inlib/frontmatter.js
. - This frontmatter value is currently required for all pages.
- The
*
is used to denote all releases for the version.
Example that applies to GitHub.com and recent versions of GitHub Enterprise Server:

If you see two single quotes in a row (''
) in YML frontmatter where you might expect to see one ('
), this is the YML-preferred way to escape a single quote. From the YAML spec:
In single quoted leaves, a single quote character needs to be escaped. This is done by repeating the character.
As an alternative, you can change the single quotes surrounding the frontmatter field to double quotes and leave interior single quotes unescaped.
Every article on the help site displays an autogenerated "In this article" section (aka mini TOC) at the top of the page that includes links to all H2
s and H3
s in the article by default.
- To make the mini TOC include additional (or fewer) heading levels, you can add
miniTocMaxHeadingLevel
frontmatter to specify the maximum heading level. For example:miniTocMaxHeadingLevel: 4
- To disable the mini TOC for a specific article, you can add this frontmatter:
showMiniToc: false
Mini TOCs do not appear on product landing pages, category landing pages, or map topic pages.
Make sure not to add hardcoded "In this article" sections in the Markdown source or else the page will display duplicate mini TOCs.
A content file can have two types of versioning:
versions
frontmatter (required)- Determines in which the versions the page is available. See contributing/permalinks for more info.
- Liquid statements in content (optional)
- Conditionally render content depending on the current version being viewed. See contributing/liquid-helpers for more info. Note Liquid conditionals can also appear in
data
andinclude
files.
- Conditionally render content depending on the current version being viewed. See contributing/liquid-helpers for more info. Note Liquid conditionals can also appear in
When adding a new article, make sure the filename is a kebab-cased version of the title you use in the article's title
frontmatter. This can get tricky when a title has punctuation (such as "GitHub's Billing Plans"). A test will flag any discrepancies between title and filename. To override this requirement for a given article, you can add allowTitleToDifferFromFilename
frontmatter.
When using Liquid conditionals in lists or tables, you can use whitespace control characters to prevent the addition of newlines that would break the list or table rendering.
Just add a hyphen on either the left, right, or both sides to indicate that there should be no newline on that side. For example, this statement removes a newline on the left side:
{%- if page.version == 'dotcom' %}
These characters are especially important in index pages comprised of list items.
Local links must start with a product ID (like /actions
or /admin
), and image paths must start with /assets
. These links undergo some transformations on the server side to match the current page's language and version. The handling for these transformations lives in lib/rewrite-local-links
and lib/rewrite-asset-paths-to-s3
.
For example, if you include the following link in a content file:
/github/writing-on-github/creating-a-saved-reply
When viewed on GitHub.com docs, the link gets rendered with the language code and version:
/en/free-pro-team@latest/github/writing-on-github/creating-a-saved-reply
and when viewed on GitHub Enterprise Server docs, the version is included as well:
/en/enterprise-server@2.20/github/writing-on-github/creating-a-saved-reply
The transformation is a little different for image paths. If you include the following image path in a content file:
/assets/images/help/profile/follow-user-button.png
when viewed on GitHub Enterprise Server docs, the path gets rewritten to include S3:
https://github-images.s3.amazonaws.com/enterprise/2.20/assets/images/help/profile/follow-user-button.png
Sometimes you want to link to a Dotcom-only article in Enterprise content and you don't want the link to be Enterprise-ified. To prevent the transformation, write the link using HTML and add a class of dotcom-only
. For example:
<a href="/github/site-policy/github-terms-of-service" class="dotcom-only">GitHub's Terms of Service</a>
Sometimes the canonical home of content moves outside the docs site. None of the links included in lib/redirects/external-redirects.json
get rewritten. See contributing/redirects.md
for more info about this type of redirect.
