You can do headers by underlining or by prefixing with the # character:

This is an H1
=============

This is an H2
-------------

# This is another H1

## This is another H2

You can do blockquotes using email-style prefixes with the > character:

> This is a quotation
> over many lines
> > and it can be nested(!)

Lists work like you'd expect, by prefixing with any of the *, +, or - characters:

Check out this list:

* This
* is
* a list..

You need a blank line between a paragraph and the start of a list for the renderer to pick up on it.

Emphasis can be added like this:

*italics*
_italics_
**bold**
__bold__

You can save your code references from being misinterpreted as emphasis by surrounding them with backtick characters (`):

Use `the_best_function()` and _not_ that crummy one.

Links look like this:

[text](http://getfedora.org)

..but we also support bare links if you just provide a URL.

You can create code blocks by indenting every line of the block by at least 4 spaces or 1 tab.

Here is a code block:

    for i in range(4):
        print i
    print "done."

You can reference bug reports by simply writing something of the form tracker#ticketid.

This fixes PHP#1234 and Python#2345

... we will automatically generate links to the tickets in the appropriate trackers in place.

The supported bug tracker prefixes are: (these are all case-insensitive)

• Fedora, RHBZ and RH (all point to the Red Hat Bugzilla)
• GNOME
• KDE
• PEAR
• PHP
• Python

And you can refer to other users by prefixing their username with the @ symbol.

Thanks @mattdm!

This will generate a link to their profile, but it won't necessarily send them a notification unless they have a special FMN rule set up to catch it.

Lastly, you can embed inline images with syntax like this:

![Alt text](/path/to/img.jpg)
