Blockquotes
As Kanye West said: > We're living the future so > the present is our past.
Syntax highlighting with GFM
```javascript
function fancyAlert(arg) {
if(arg) {
$.facebox({div:'#foo'})
}
}
```
Or, indent your code 4 spaces
Here is a Python code example
without syntax highlighting:
def foo:
if not bar:
return true
Inline code for comments
I think you should use an `<addr>` element here instead.
