<h2>Getting the Gist of Markdown's Formatting Syntax</h2>

<p>This page offers a brief overview of what it's like to use Markdown.
The <a href="/projects/markdown/syntax" title="Markdown Syntax">syntax page</a> provides complete, detailed documentation for
every feature, but Markdown should be very easy to pick up simply by
looking at a few examples of it in action. The examples on this page
are written in a before/after style, showing example syntax and the
HTML output produced by Markdown.</p>

<p>It's also helpful to simply try Markdown out; the <a href="/projects/markdown/dingus" title="Markdown Dingus">Dingus</a> is a
web application that allows you type your own Markdown-formatted text
and translate it to XHTML.</p>

<p><strong>Note:</strong> This document is itself written using Markdown; you
can <a href="/projects/markdown/basics.text">see the source for it by adding '.text' to the URL</a>.</p>

<h2>Paragraphs, Headers, Blockquotes</h2>

<p>A paragraph is simply one or more consecutive lines of text, separated
by one or more blank lines. (A blank line is any line that looks like a
blank line -- a line containing nothing spaces or tabs is considered
blank.) Normal paragraphs should not be intended with spaces or tabs.</p>

<p>Markdown offers two styles of headers: <em>Setext</em> and <em>atx</em>.
Setext-style headers for <code>&lt;h1&gt;</code> and <code>&lt;h2&gt;</code> are created by
&quot;underlining&quot; with equal signs (<code>=</code>) and hyphens (<code>-</code>), respectively.
To create an atx-style header, you put 1-6 hash marks (<code>#</code>) at the
beginning of the line -- the number of hashes equals the resulting
HTML header level.</p>

<p>Blockquotes are indicated using email-style '<code>&gt;</code>' angle brackets.</p>

<p>Markdown:</p>

<pre><code>A First Level Header
====================

A Second Level Header
---------------------

Now is the time for all good men to come to
the aid of their country. This is just a
regular paragraph.

The quick brown fox jumped over the lazy
dog's back.

### Header 3

&gt; This is a blockquote.
&gt; 
&gt; This is the second paragraph in the blockquote.
&gt;
&gt; ## This is an H2 in a blockquote
</code></pre>

<p>Output:</p>

<pre><code>&lt;h1&gt;A First Level Header&lt;/h1&gt;

&lt;h2&gt;A Second Level Header&lt;/h2&gt;

&lt;p&gt;Now is the time for all good men to come to
the aid of their country. This is just a
regular paragraph.&lt;/p&gt;

&lt;p&gt;The quick brown fox jumped over the lazy
dog's back.&lt;/p&gt;

&lt;h3&gt;Header 3&lt;/h3&gt;

&lt;blockquote&gt;
    &lt;p&gt;This is a blockquote.&lt;/p&gt;

    &lt;p&gt;This is the second paragraph in the blockquote.&lt;/p&gt;

    &lt;h2&gt;This is an H2 in a blockquote&lt;/h2&gt;
&lt;/blockquote&gt;
</code></pre>

<h3>Phrase Emphasis</h3>

<p>Markdown uses asterisks and underscores to indicate spans of emphasis.</p>

<p>Markdown:</p>

<pre><code>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__.
</code></pre>

<p>Output:</p>

<pre><code>&lt;p&gt;Some of these words &lt;em&gt;are emphasized&lt;/em&gt;.
Some of these words &lt;em&gt;are emphasized also&lt;/em&gt;.&lt;/p&gt;

&lt;p&gt;Use two asterisks for &lt;strong&gt;strong emphasis&lt;/strong&gt;.
Or, if you prefer, &lt;strong&gt;use two underscores instead&lt;/strong&gt;.&lt;/p&gt;
</code></pre>

<h2>Lists</h2>

<p>Unordered (bulleted) lists use asterisks, pluses, and hyphens (<code>*</code>,
<code>+</code>, and <code>-</code>) as list markers. These three markers are
interchangable; this:</p>

<pre><code>*   Candy.
*   Gum.
*   Booze.
</code></pre>

<p>this:</p>

<pre><code>+   Candy.
+   Gum.
+   Booze.
</code></pre>

<p>and this:</p>

<pre><code>-   Candy.
-   Gum.
-   Booze.
</code></pre>

<p>all produce the same output:</p>

<pre><code>&lt;ul&gt;
&lt;li&gt;Candy.&lt;/li&gt;
&lt;li&gt;Gum.&lt;/li&gt;
&lt;li&gt;Booze.&lt;/li&gt;
&lt;/ul&gt;
</code></pre>

<p>Ordered (numbered) lists use regular numbers, followed by periods, as
list markers:</p>

<pre><code>1.  Red
2.  Green
3.  Blue
</code></pre>

<p>Output:</p>

<pre><code>&lt;ol&gt;
&lt;li&gt;Red&lt;/li&gt;
&lt;li&gt;Green&lt;/li&gt;
&lt;li&gt;Blue&lt;/li&gt;
&lt;/ol&gt;
</code></pre>

<p>If you put blank lines between items, you'll get <code>&lt;p&gt;</code> tags for the
list item text. You can create multi-paragraph list items by indenting
the paragraphs by 4 spaces or 1 tab:</p>

<pre><code>*   A list item.

    With multiple paragraphs.

*   Another item in the list.
</code></pre>

<p>Output:</p>

<pre><code>&lt;ul&gt;
&lt;li&gt;&lt;p&gt;A list item.&lt;/p&gt;
&lt;p&gt;With multiple paragraphs.&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;Another item in the list.&lt;/p&gt;&lt;/li&gt;
&lt;/ul&gt;
</code></pre>

<h3>Links</h3>

<p>Markdown supports two styles for creating links: <em>inline</em> and
<em>reference</em>. With both styles, you use square brackets to delimit the
text you want to turn into a link.</p>

<p>Inline-style links use parentheses immediately after the link text.
For example:</p>

<pre><code>This is an [example link](http://example.com/).
</code></pre>

<p>Output:</p>

<pre><code>&lt;p&gt;This is an &lt;a href=&quot;http://example.com/&quot;&gt;
example link&lt;/a&gt;.&lt;/p&gt;
</code></pre>

<p>Optionally, you may include a title attribute in the parentheses:</p>

<pre><code>This is an [example link](http://example.com/ &quot;With a Title&quot;).
</code></pre>

<p>Output:</p>

<pre><code>&lt;p&gt;This is an &lt;a href=&quot;http://example.com/&quot; title=&quot;With a Title&quot;&gt;
example link&lt;/a&gt;.&lt;/p&gt;
</code></pre>

<p>Reference-style links allow you to refer to your links by names, which
you define elsewhere in your document:</p>

<pre><code>I get 10 times more traffic from [Google][1] than from
[Yahoo][2] or [MSN][3].

[1]: http://google.com/        &quot;Google&quot;
[2]: http://search.yahoo.com/  &quot;Yahoo Search&quot;
[3]: http://search.msn.com/    &quot;MSN Search&quot;
</code></pre>

<p>Output:</p>

<pre><code>&lt;p&gt;I get 10 times more traffic from &lt;a href=&quot;http://google.com/&quot;
title=&quot;Google&quot;&gt;Google&lt;/a&gt; than from &lt;a href=&quot;http://search.yahoo.com/&quot;
title=&quot;Yahoo Search&quot;&gt;Yahoo&lt;/a&gt; or &lt;a href=&quot;http://search.msn.com/&quot;
title=&quot;MSN Search&quot;&gt;MSN&lt;/a&gt;.&lt;/p&gt;
</code></pre>

<p>The title attribute is optional. Link names may contain letters,
numbers and spaces, but are <em>not</em> case sensitive:</p>

<pre><code>I start my morning with a cup of coffee and
[The New York Times][NY Times].

[ny times]: http://www.nytimes.com/
</code></pre>

<p>Output:</p>

<pre><code>&lt;p&gt;I start my morning with a cup of coffee and
&lt;a href=&quot;http://www.nytimes.com/&quot;&gt;The New York Times&lt;/a&gt;.&lt;/p&gt;
</code></pre>

<h3>Images</h3>

<p>Image syntax is very much like link syntax.</p>

<p>Inline (titles are optional):</p>

<pre><code>![alt text](/path/to/img.jpg &quot;Title&quot;)
</code></pre>

<p>Reference-style:</p>

<pre><code>![alt text][id]

[id]: /path/to/img.jpg &quot;Title&quot;
</code></pre>

<p>Both of the above examples produce the same output:</p>

<pre><code>&lt;img src=&quot;/path/to/img.jpg&quot; alt=&quot;alt text&quot; title=&quot;Title&quot; /&gt;
</code></pre>

<h3>Code</h3>

<p>In a regular paragraph, you can create code span by wrapping text in
backtick quotes. Any ampersands (<code>&amp;</code>) and angle brackets (<code>&lt;</code> or
<code>&gt;</code>) will automatically be translated into HTML entities. This makes
it easy to use Markdown to write about HTML example code:</p>

<pre><code>I strongly recommend against using any `&lt;blink&gt;` tags.

I wish SmartyPants used named entities like `&amp;mdash;`
instead of decimal-encoded entites like `&amp;#8212;`.
</code></pre>

<p>Output:</p>

<pre><code>&lt;p&gt;I strongly recommend against using any
&lt;code&gt;&amp;lt;blink&amp;gt;&lt;/code&gt; tags.&lt;/p&gt;

&lt;p&gt;I wish SmartyPants used named entities like
&lt;code&gt;&amp;amp;mdash;&lt;/code&gt; instead of decimal-encoded
entites like &lt;code&gt;&amp;amp;#8212;&lt;/code&gt;.&lt;/p&gt;
</code></pre>

<p>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, <code>&amp;</code>, <code>&lt;</code>,
and <code>&gt;</code> characters will be escaped automatically.</p>

<p>Markdown:</p>

<pre><code>If you want your page to validate under XHTML 1.0 Strict,
you've got to put paragraph tags in your blockquotes:

    &lt;blockquote&gt;
        &lt;p&gt;For example.&lt;/p&gt;
    &lt;/blockquote&gt;
</code></pre>

<p>Output:</p>

<pre><code>&lt;p&gt;If you want your page to validate under XHTML 1.0 Strict,
you've got to put paragraph tags in your blockquotes:&lt;/p&gt;

&lt;pre&gt;&lt;code&gt;&amp;lt;blockquote&amp;gt;
    &amp;lt;p&amp;gt;For example.&amp;lt;/p&amp;gt;
&amp;lt;/blockquote&amp;gt;
&lt;/code&gt;&lt;/pre&gt;
</code></pre>
