To view the content available for your platform, make sure that you select the correct version of this article from the version selector which is located above the table of contents. Feature support differs depending on whether you are working from Azure DevOps Services or an on-premises version of Azure DevOps Server, renamed from Team Foundation Server (TFS).
To learn which on-premises version you are using, see What platform/version am I using?
In this article, find some Wiki-specific Markdown syntax guidance for use in Azure DevOps.
Table of contents (TOC) for Wiki pages
To create a table of contents, add a [[_TOC_]]. The TOC is generated when the tag is added and there's at least one heading on the page.
The [[_TOC_]] can be placed anywhere in the page to render the table of contents. Only Markdown headings are considered for TOC (HTML heading tags aren't).
All HTML and Markdown tags are stripped from the headings while adding it inside the TOC block. For example: Adding bold and italics to a heading text renders the TOC as follows.
Consistency is maintained in the formatting in TOC.
The tag [[_TOC_]] is case-sensitive. For example, [[_toc_]] may not render the TOC. Also, only the first instance of [[_TOC_]] is rendered and the rest are ignored.
Add Mermaid diagrams to a Wiki page
Wiki supports the following Mermaid diagram types:
To add Mermaid diagrams to a wiki page, use the following syntax:
::: mermaid <mermaid diagram syntax> :::
There's also a toolbar button to add a default Mermaid diagram to a wiki page.
Most HTML tags and fontawesome aren't supported in the Mermaid diagram syntax. Mermaid isn't supported in the Internet Explorer browser.
This feature is supported only in Azure DevOps Services (not in Azure DevOps Server).
Embed videos in a Wiki page
To embed videos from YouTube and Microsoft Streams in a wiki page, use the following syntax:
::: video <iframe width="560" height="315" src="https://www.youtube.com/embed/OtqFyBA6Dbk" frameborder="0" allow="autoplay; encrypted-media" allowfullscreen></iframe> :::
The iframe is the embed iframe block of the YouTube or Microsoft Streams video.
(The ending ":::" is required to prevent a break in the page)
Any file that contains a YAML block in a Wiki is processed by a table with one head and one row. The YAML block must be the first thing in the file and must take the form of valid YAML set between triple-dashed lines. It supports all basic datatypes, lists, and objects as values. The syntax is supported in wiki, code file preview.
--- tag: post title: Hello world ---
Tags with list:
--- tags: - post - code - web title: Hello world ---
Embed Azure Boards query results in Wiki
To embed Azure Boards query results in a wiki page as a table, use the following syntax:
::: query-table <queryid> :::
You can also use the toolbar icon and the query selector to embed the query results in a wiki page.
@mention users and groups
To @mention users or groups in wiki, key in "@" in the wiki editor. This @mention opens autosuggest, from which you can mention users or groups to get notified by email.
You can also select "@mention" from the edit toolbar.
Page visits for wiki pages
Automatically, you see an aggregated page visits count for the last 30 days on every page.
Use the batch API
pagesBatch to see the daily quantity of visits to all pages in a paginated way. They aren't sorted by number of visits, however. For data over 30 days old, you can get all page visits using the rest API. Sort these pages based on the number of visits to get the top 100. You can store these visits in a dashboard or database.
A page visit is defined as a page view by a given user in a 15-minute interval.
Link to work items from a Wiki page
Enter the pound sign (
#), and then enter a work item ID.
This feature is available with TFS 2018.2 and later versions.
HTML tag support in wiki pages
In wiki pages, you can also create rich content using HTML tags. (You can nest markdown within your HTML, but you must include a blank line between the HTML element and the markdown.)
<p> [A markdown link](https://microsoft.com) </p>
Pasting rich content as HTML is supported in Azure DevOps Server 2019.1 and later versions.
Example - Embedded video
<video src="path of the video file" width=400 controls> </video>
<video src="https://sec.ch9.ms/ch9/7247/7c8ddc1a-348b-4ba9-ab61-51fded6e7247/vstswiki_high.mp4" width=400 controls> </video>
Example - Rich text format
<p>This text needs to <del>strikethrough</del> <ins>since it is redundant</ins>!</p> <p><tt>This text is teletype text.</tt></p> <font color="blue">Colored text</font> <center>This text is center-aligned.</center> <p>This text contains <sup>superscript</sup> text.</p> <p>This text contains <sub>subscript</sub> text.</p> <p>The project status is <span style="color:green;font-weight:bold">GREEN</span> even though the bug count / developer may be in <span style="color:red;font-weight:bold">red.</span> - Capability of span <p><small>Disclaimer: Wiki also supports showing small text</small></p> <p><big>Bigger text</big></p>
