段落
段落就是被空行分割的文本；空行可以是空格和制表符；并且，正常的段落是没有缩进的；
Markdown的一些属性会影响一段；为了上下内容不被这些属性影响，中间插入空行。
标题
标题有两种格式; Setext 和 atx
Setext 使用等号=和连字符-分别定义一级和二级标题；
atx使用#, 在一行开始加1-6个#分别定义1-6级标题；
引用
使用尖括号>定义
Markdown:
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
> This is a blockquote.
>
> This is the second paragraph in the blockquote.
>
> ## This is an H2 in a blockquote
HTML Output:
<h1>A First Level Header</h1>
<h2>A Second Level Header</h2>
<p>Now is the time for all good men to come to
the aid of their country. This is just a
regular paragraph.</p>
<p>The quick brown fox jumped over the lazy
dog's back.</p>
<h3>Header 3</h3>
<blockquote>
<p>This is a blockquote.</p>
<p>This is the second paragraph in the blockquote.</p>
<h2>This is an H2 in a blockquote</h2>
</blockquote>
强调-斜体与加粗
星号与下划线用来标记强调；
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__.
HTML Output:
<p>Some of these words <em>are emphasized</em>.
Some of these words <em>are emphasized also</em>.</p>
<p>Use two asterisks for <strong>strong emphasis</strong>.
Or, if you prefer, <strong>use two underscores instead</strong>.</p>
列表
列表分为无序和有序两种；
无序列表：*，+, -标记
* Candy.
* Gum.
* Booze.
+ Candy.
+ Gum.
+ Booze.
- Candy.
- Gum.
- Booze.
HTML Output:
<ul>
<li>Candy.</li>
<li>Gum.</li>
<li>Booze.</li>
</ul>
有序列表使用数字定义：
1. Red
2. Green
3. Blue
HTML Output:
<ol>
<li>Red</li>
<li>Green</li>
<li>Blue</li>
</ol>
链接
分为内联与引用，都是使用中括号将文本定义为链接；
内联：
This is an [example link](http://example.com/).
HTML Output:
<p>This is an <a href="http://example.com/">
example link</a>.</p>
参考链接：
你可以在任何位置定义好链接，然后引用即可；
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:
<p>I get 10 times more traffic from <a href="http://google.com/"
title="Google">Google</a> than from <a href="http://search.yahoo.com/"
title="Yahoo Search">Yahoo</a> or <a href="http://search.msn.com/"
