Markdown is a way to style text on the web. You control the display of the document; formatting words as bold or italic, adding images, and creating lists are just a few of the things we can do with Markdown. Mostly, Markdown is just regular text with a few non-alphabetic characters thrown in, like # or *.
You can use Markdown most places around GitHub:
- Gists
- Comments in Issues and Pull Requests
- Files with the
.mdor.markdownextension
For more information, see “Writing on GitHub” in the GitHub Help.

I think you should use an
`<addr>` element here instead.
GitHub.com uses its own version of the Markdown syntax that provides an additional set of useful features, many of which make it easier to work with content on GitHub.com.
Note that some features of GitHub Flavored Markdown are only available in the descriptions and comments of Issues and Pull Requests. These include @mentions as well as references to SHA-1 hashes, Issues, and Pull Requests. Task Lists are also available in Gist comments and in Gist Markdown files.
Here’s an example of how you can use syntax highlighting with GitHub Flavored Markdown:
```javascript
function fancyAlert(arg) {
if(arg) {
$.facebox({div:'#foo'})
}
}
```maYou can also simply indent your code by four spaces:
function fancyAlert(arg) {
if(arg) {
$.facebox({div:'#foo'})
}
}Here’s an example of Python code without syntax highlighting:
def foo():
if not bar:
return True- [x] @mentions, #refs, [links](), **formatting**, and <del>tags</del> supported
- [x] list syntax required (any unordered or ordered list supported)
- [x] this is a complete item
- [ ] this is an incomplete itemIf you include a task list in the first comment of an Issue, you will get a handy progress indicator in your issue list. It also works in Pull Requests!
You can create tables by assembling a list of words and dividing them with hyphens - (for the first row), and then separating each column with a pipe |:
First Header | Second Header
------------ | -------------
Content from cell 1 | Content from cell 2
Content in the first column | Content in the second columnWould become:
| First Header | Second Header |
|---|---|
| Content from cell 1 | Content from cell 2 |
| Content in the first column | Content in the second column |
Any reference to a commit’s SHA-1 hash will be automatically converted into a link to that commit on GitHub.

Any number that refers to an Issue or Pull Request will be automatically converted into a link.

Typing an @ symbol, followed by a username, will notify that person to come and view the comment. This is called an “@mention”, because you’re _mentioning_the individual. You can also @mention teams within an organization.
Any URL (like http://www.github.com/) will be automatically converted into a clickable link.
Any word wrapped with two tildes (like ~~this~~) will appear crossed out.
