Syntax guidance for basic Markdown usage

TFS 2017 | TFS 2015

Here you can find some basic Markdown syntax guidance and specific guidance for using Markdown in Azure DevOps features. You can use both common Markdown conventions and GitHub-flavored extensions.

Having the right guidance at the right time is critical to success. Use Markdown to add rich formatting, tables, and images to your project pages, README files, dashboards, and pull request comments.

For more syntax that's supported for Wiki pages, see Wiki Markdown guidance.

You can provide guidance in the following areas using Markdown:

• Markdown widget added to a dashboard
• Project page or Welcome pages
• Repository README files
• Pull request (PR) comments
• Definition of Done (Kanban board)

Headers

Supported in: Definition of Done | Markdown widget | Pull Requests | README files

Structure your comments using headers. Headers segment longer comments, making them easier to read.

Start a line with a hash character # to set a heading. Organize your remarks with subheadings by starting a line with more hash characters, for example ####. Up to six levels of headings are supported.

Example:

# This is a H1 header
## This is a H2 header
### This is a H3 header
#### This is a H4 header
##### This is a H5 header

Result:

Paragraphs and line breaks

Supported in: Definition of Done | Markdown widget | Pull Requests | README files

Make your text easier to read by breaking it into paragraphs or with line breaks.

Pull requests

In pull request comments, select Enter to insert a line break, and begin text on a new line.

Example - pull request comment:

Add lines between your text with the **Enter** key.
Your text gets better spaced and makes it easier to read.

Result:

Add lines between your text with the Enter key.

Your text gets better spaced and makes it easier to read.

Markdown files or widgets

In a Markdown file or widget, enter two spaces before the line break, and then select Enter to begin a new paragraph.

Example - Markdown file or widget:

Add two spaces before the end of the line, and then select **Enter**.(space, space, Enter)
A space gets added in between paragraphs.

Result:

Add two spaces before the end of the line, and then select Enter.

A space gets added in between paragraphs.

Blockquotes

Supported in: Definition of Done | Markdown widget | Pull Requests | README files

Quote previous comments or text to set the context for your comment or text.

Quote single lines of text with > before the text. Use many > characters to nest quoted text. Quote blocks of lines of text by using the same level of > across many lines.

Example:

> Single line quote
>> Nested quote
>> multiple line
>> quote

Result:

Horizontal rules

Supported in: Definition of Done | Markdown widget | Pull Requests | README files

To add a horizontal rule, add a line that's a series of dashes ---. The line above the line containing the --- must be blank.

Example:

above
 
----
below

Result:

above

below

Emphasis (bold, italics, strikethrough)

Supported in: Definition of Done | Markdown widget | Pull Requests | README files

You can emphasize text by applying bold, italics, or strikethrough to characters:

• To apply italics: surround the text with an asterisk * or underscore _
• To apply bold: surround the text with double asterisks **.
• To apply strikethrough: surround the text with double tilde characters ~~.

Combine these elements to apply emphasis to text.

Example:

Use _emphasis_ in comments to express **strong** opinions and point out ~~corrections~~  
**_Bold, italicized text_**  
**~~Bold, strike-through text~~**

Result:

Use emphasis in comments to express strong opinions and point out corrections
Bold, italicized text Bold, strike-through text

Code highlighting

Supported in: Pull Requests | README files

Highlight suggested code segments using code highlight blocks. To indicate a span of code, wrap it with three backtick quotes (```) on a new line at both the start and end of the block. To indicate code inline, wrap it with one backtick quote (`).

Example:

```
sudo npm install vsoagent-installer -g  
```

Result:

sudo npm install vsoagent-installer -g

Example:

To install the Microsoft Cross Platform Build & Release Agent, run the following: `$ sudo npm install vsoagent-installer -g`.

Result:

To install the Microsoft Cross Platform Build & Release Agent, run the following command: $ sudo npm install vsoagent-installer -g.

Within a Markdown file, text with four spaces at the beginning of the line automatically converts to a code block.

Set a language identifier for the code block to enable syntax highlighting for any of the supported languages in highlightjs, version v9.10.0.

``` language
code
```

More examples:

``` js
const count = records.length;
```

const count = records.length;

``` csharp
Console.WriteLine("Hello, World!");
```

Console.WriteLine("Hello, World!");

Tables

Supported in: Markdown widget | Pull Requests | README files

Organize structured data with tables. Tables are especially useful for describing function parameters, object methods, and other data that have a clear name to description mapping. You can format tables in pull requests, wiki, and Markdown files such as README files and Markdown widgets.

• Place each table row on its own line
• Separate table cells using the pipe character |
• The first two lines of a table set the column headers and the alignment of elements in the table
• Use colons (:) when dividing the header and body of tables to specify column alignment (left, center, right)
• To start a new line, use the HTML break tag (<br/>) (Works within a Wiki but not elsewhere)
• Make sure to end each row with a CR or LF.
• A blank space is required before and after work item or pull request (PR) mentions inside a table cell.

Example:

| Heading 1 | Heading 2 | Heading 3 |  
|-----------|:-----------:|-----------:|  
| Cell A1 | Cell A2 | Cell A3 |  
| Cell B1 | Cell B2 | Cell B3<br/>second line of text |  

Result:

Lists

Supported in: Definition of Done | Markdown widget | Pull Requests | README files

Organize related items with lists. You can add ordered lists with numbers, or unordered lists with just bullets.

Ordered lists start with a number followed by a period for each list item. Unordered lists start with a -. Begin each list item on a new line. In a Markdown file or widget, enter two spaces before the line break to begin a new paragraph, or enter two line breaks consecutively to begin a new paragraph.

Ordered or numbered lists

Example:

1. First item.
1. Second item.
1. Third item.

Result:

1. First item.
2. Second item.
3. Third item.

Bulleted lists

Example:

- Item 1
- Item 2
- Item 3

Result:

• Item 1
• Item 2
• Item 3

Nested lists

Example:

1. First item.
   - Item 1
   - Item 2
   - Item 3
1. Second item.
   - Nested item 1
      - Further nested item 1
      - Further nested item 2
      - Further nested item 3
   - Nested item 2
   - Nested item 3

Result:

1. First item.
   • Item 1
   • Item 2
   • Item 3
2. Second item.
   • Nested item 1
     • Further nested item 1
     • Further nested item 2
     • Further nested item 3
   • Nested item 2
   • Nested item 3

Links

Supported in: Definition of Done | Markdown widget | Pull Requests | README files

In pull request comments and wikis, HTTP and HTTPS URLs are automatically formatted as links. You can link to work items by entering the # key and a work item ID, and then choosing the work item from the list.

Avoid auto suggestions for work items by prefixing # with a backslash (\). This action can be useful if you want to use # for color hex codes.

In Markdown files and widgets, you can set text hyperlinks for your URL using the standard Markdown link syntax:

[Link Text](Link URL)

When you're linking to another Markdown page in the same Git or TFVC repository, the link target can be a relative path or an absolute path in the repository.

Supported links for Welcome pages:

• Relative path: [text to display](target.md)
• Absolute path in Git: [text to display](/folder/target.md)
• Absolute path in TFVC: [text to display]($/project/folder/target.md)
• URL: [text to display](http://address.com)

Supported links for Markdown widget:

• URL: [text to display](http://address.com)

Supported links for Wiki:

• Absolute path of Wiki pages: [text to display](/parent-page/child-page)
• URL: [text to display](http://address.com)

Example:

[C# language reference](/dotnet/csharp/language-reference/)

Result:

C# language reference

Checklist or task list

Supported in: Pull Requests | Wikis

Lightweight task lists are great ways to track progress on your to-dos as a pull request creator or reviewer in the PR description or in a wiki page. Select the Markdown toolbar to get started or apply the format to selected text.

You can Use [ ] or [x] to support checklists. Precede the checklist with either -<space> or 1.<space> (any numeral).

Example - Apply the task list Markdown to a highlighted list

After you've added a task list, you can check the boxes to mark items as completed. These actions are expressed and stored within the comment as [ ] and [x] in Markdown.

Example - Format a list as a task list

- [ ] A  
- [ ] B  
- [ ] C  
- [x] A  
- [x] B  
- [x] C

Emoji

Supported in: Pull Requests

In pull request comments, you can use emojis to add characters and react to comments in the request. Enter what you're feeling surrounded by : characters to get a matching emoji in your text. The full set of emojis are supported.

Example:

:smile:
:angry:

Result:

To escape emojis, enclose them using the ` character.

Example:

`:smile:` `:)` `:angry:`

Result:

:smile: :) :angry:

Ignore or escape Markdown syntax to enter specific or literal characters

Attachments

Supported in: Pull Requests | README files

In pull request comments, you can attach files to illustrate your point or to give more detailed reasoning behind your suggestions. To attach a file, drag and drop it into the comment field. You can also select the paperclip in the upper right of the comment box.

If you have an image in your clipboard, you can paste it from the clipboard into the comment box or wiki page and it renders directly into your comment or wiki page.

Attaching non-image files creates a link to the file in your comment. Update the description text between the brackets to change the text displayed in the link. Attached image files render directly into your comment or wiki pages. After you save or update a comment or wiki page with an attachment, you can see the attached image and select links to download attached files.

Attachments support the following file formats.
