PHRASE EMPHASIS
Markdown uses asterisks and underscores to indicate spans of emphasis. -----------------------------------------------------------------------------------------------------------------------------
Markdown:
Some of these words *are emphasized*. Some of these words _are emphasized also_.
Use two asterisks for **strong emphasis**. Or, if you prefer, __use two underscores instead__. Output:
Some of these words
are emphasized
. Some of these words
are emphasized also
.
Use two asterisks for
strong emphasis
. Or, if you prefer,
use two underscores instead
.
LISTS
Unordered (bulleted) lists use asterisks, pluses, and hyphens (*, +, and -) as list markers. These three markers are interchangable; this:
* Candy. * Gum. * Booze. this:
+ Candy. + Gum. + Booze. and this:
- Candy. - Gum. - Booze. all produce the same output:
Candy.
Gum.
Booze.
Ordered (numbered) lists use regular numbers, followed by periods, as list markers:
1. Red 2. Green 3. Blue Output:
Red
Green
Blue
If you put blank lines between items, you’ll get
tags for the list item text. You can create multi-paragraph list items by indenting the paragraphs by 4 spaces or 1 tab:
* A list item.
With multiple paragraphs.
* Another item in the list.
Output:
A list item.
With multiple paragraphs.
Another item in the list.
LINKS
Markdown supports two styles for creating links: inline and reference. With both styles, you use square brackets to delimit the text you want to turn into a link.
Inline-style links use parentheses immediately after the link text. For example:
This is an [example link](http://example.com/). Output:
This is an
example link
.
Optionally, you may include a title attribute in the parentheses:
This is an [example link](http://example.com/ "With a Title"). Output:
This is an
example link
.
Reference-style links allow you to refer to your links by names, which you define elsewhere in your document:
I get 10 times more traffic from [Google][1] than from [Yahoo][2] or [MSN][3].
[1]: http://google.com/ "Google" [2]: http://search.yahoo.com/ "Yahoo Search" [3]: http://search.msn.com/ "MSN Search" Output:
I get 10 times more traffic from
than from
Yahoo
or
MSN
.
The title attribute is optional. Link names may contain letters, numbers and spaces, but are not case sensitive:
I start my morning with a cup of coffee and [The New York Times][NY Times].
[ny times]: http://www.nytimes.com/ Output:
I start my morning with a cup of coffee and
The New York Times
.
IMAGES
Image syntax is very much like link syntax.
Inline (titles are optional):
 Reference-style:
![alt text][id]
[id]: /path/to/img.jpg "Title" Both of the above examples produce the same output:

CODE
In a regular paragraph, you can create code span by wrapping text in backtick quotes. Any ampersands (&) and angle brackets (< or >) will automatically be translated into HTML entities. This makes it easy to use Markdown to write about HTML example code:
I strongly recommend against using any `
` tags.
I wish SmartyPants used named entities like `—` instead of decimal-encoded entites like `—`. Output:
I strongly recommend against using any
<blink>
tags.
I wish SmartyPants used named entities like
&mdash;
instead of decimal-encoded entites like
&#8212;
.
To specify an entire block of pre-formatted code, indent every line of the block by 4 spaces or 1 tab. Just like with code spans, &, <, and > characters will be escaped automatically.
----------------------------------------------------------------------------------------------------------------------------- Markdown:
If you want your page to validate under XHTML 1.0 Strict, you've got to put paragraph tags in your blockquotes:
For example.
Output:
If you want your page to validate under XHTML 1.0 Strict, you've got to put paragraph tags in your blockquotes:
<blockquote> <p>For example.</p> </blockquote>
