Markdown syntax guide

Bitbucket Data Center and Server uses Markdown for formatting text, as specified in CommonMark (with a few extensions).

You can use Markdown in the following places:

  • any pull request's descriptions or comments, or
  • in README files (if they have the .md file extension).

To preview your markdown, use Control+Shift+P or Command+Shift+P.

Note that Bitbucket Data Center and Server doesn't support HTML tags and all HTML tags are escaped.

Markdown syntax

The page below contains examples of Markdown syntax. For a full list of all the Markdown syntax, consult the CommonMark help or specification.

Quotes or citations

Introducing my quote:

> Neque porro quisquam est qui 
> dolorem ipsum quia dolor sit amet, 
> consectetur, adipisci velit...

Inline code characters

Use the backtick to refer to a `function()`.
There is a literal ``backtick (`)`` here.

Code blocks

Indent every line of the block by at least 4 spaces.

This is a normal paragraph:

    This is a code block.
    With multiple lines.

Alternatively, you can use 3 backtick quote marks before and after the block, like this:

This is a code block

To add syntax highlighting to a code block, add the name of the language immediately
after the backticks: 

var oldUnload = window.onbeforeunload;
window.onbeforeunload = function() {
    if (oldUnload) {
        return oldUnload.apply(this, arguments);

Bitbucket uses CodeMirror to apply syntax highlighting to the rendered markdown in comments, READMEs and pull request descriptions. All the common coding languages are supported, including C, C++, Java, Scala, Python and JavaScript. See Configuring syntax highlighting for file extensions.

Within a code block, ampersands (&) and angle brackets (< and >) are automatically converted into HTML entities.

Links to external websites

This is [an example]( inline link.

[This link]( "Title") has a title attribute.

Links are also auto-detected in text:

Linking issue keys to JIRA applications

When you use Jira application issue keys (of the default format) in comments and pull request descriptions Bitbucket automatically links them to the Jira application instance.

The default Jira application issue key format is two or more uppercase letters ([A-Z][A-Z]+), followed by a hyphen and the issue number, for example TEST-123.

Linking to pull requests

Introduced with Bitbucket 4.9, you can reference pull requests from comments and descriptions in other pull requests. The syntax for linking to pull request looks like this: 


To link to a pull request in the same project and repository, you only need to include the pull request ID. 


To link to a pull request in the same project but a different repository, include the repository slug before the pull request ID.


To link to a pull request in a different project and repository, include the project key and the repository slug before the pull request ID.



Inline image syntax looks like this:

![Alt text](/path/to/image.jpg)
![Alt text](/path/to/image.png "Optional title attribute")
![Alt text](/url/to/image.jpg)


![Mockup for feature A](

Reference image links look like this:

![Alt text][id]

Where 'id' is the name of a previously defined image reference, using syntax similar to link references:

[id]: url/to/image.jpg "Optional title attribute"

An example using reference image links:

<--Collected image definitions-->
[MockupA]: "Screenshot of Feature A mockup" 
<!--Using an image reference-->
![Mockup for feature A][MockupA]

You can specify image height and width as key=value pairs inside curly braces { } after the applicable image node. For example:

![text](/url.png){width=640 height=480}

| Day     | Meal    | Price |
| --------|---------|-------|
| Monday  | pasta   | $6    |
| Tuesday | chicken | $8    |

Backslash escapes

Certain characters can be escaped with a preceding backslash to preserve the literal display of a character instead of its special Markdown meaning. This applies to the following characters:

\  backslash
`  backtick
*  asterisk
_  underscore
{} curly braces
[] square brackets
() parentheses
#  hash mark
>  greater than
+  plus sign
-  minus sign (hyphen)
.  dot
!  exclamation mark

README files

If your repository contains a file at the root level, Bitbucket displays its contents on the repository's Source page if the file has the .md extension. The file can contain only Markdown.
