列表
列表项占一行，以*、+、-开头即可：
* Red
* Green
* Blue
效果：
- Red
- Green
- Blue
有序列表只需要将上述标记符换成数字加句点。而且顺序由书写顺序决定，与数字无关，但数字需要从1开始。例如：
1\. Bird
3. McHale
2. Parish
效果：
- Bird
- McHale
- Parish
每一个列表项可以多行：
* Lorem ipsum dolor sit amet, consectetuer adipiscing elit.
Aliquam hendrerit mi posuere lectus. Vestibulum enim wisi,
viverra nec, fringilla in, laoreet vitae, risus.
* Donec sit amet nisl. Aliquam semper ipsum sit amet velit.
Suspendisse id sem consectetuer libero luctus adipiscing.
效果：
- Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Aliquam hendrerit mi posuere lectus. Vestibulum enim wisi, viverra nec, fringilla in, laoreet vitae, risus.
- Donec sit amet nisl. Aliquam semper ipsum sit amet velit. Suspendisse id sem consectetuer libero luctus adipiscing.
代码块
每一行前面缩进四个或以上个空格，就认为是开始了一段代码块。代码块内原样输出。
This is a normal paragraph:
This is a code block.
效果：
This is a normal paragraph:
This is a code block.
横线
三个或更多个*、-（它们之间可以有空格）会产生横线：
* * *
效果：
链接
内嵌链接：
I get 10 times more traffic from [Google](http://google.com/ "Google")
than from [Yahoo](http://search.yahoo.com/ "Yahoo Search") or
[MSN](http://search.msn.com/ "MSN Search").
或参考文献式链接（缺省的链接标记认为与文本一致）：
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"
I get 10 times more traffic from [Google][] than from
[Yahoo][] or [MSN][].
[google]: http://google.com/ "Google"
[yahoo]: http://search.yahoo.com/ "Yahoo Search"
[msn]: http://search.msn.com/ "MSN Search"
效果：
I get 10 times more traffic from Google than from Yahoo or MSN.
如果直接以链接地址作为链接文本，可以用如下快捷写法：
[无敌大灰狼me](https://www.jianshu.com/u/e48caea06934) 效果：
强调
单个*或_产生斜体，两个（**、__）则产生粗体。例如：
*like* _this_
**like** **this**
效果：
like this
like this
内嵌代码
code: `echo hello`
效果：
code: echo hello
