标题

A First Level Header
====================
A Second Level Header
---------------------

或者, 

# Head1 
## Head2 
……

###### Head6

段落, >

> This is a blockquote. 
> Continuing...... 
> 
> This is the second paragraph in the blockquote. 
> 
> ## This is an H2 in a blockquote

可以看到除非, 显示的增加空行, 否则是不会换行的

(GFM)

Github, 这里做了改进, 等同于一般的书写习惯, 默认换行 
增加空行, 就会实际添加空行

加粗和斜体, _或*

_good_, *good*, 斜体 
__man__, **good**, 加粗

(GFM)

对于多个连续_自动忽略, 不会做斜体处理 
因为很多变量名都是

perform_complicated_task

(GFM)

Strikethrough

GFM adds syntax to strikethrough text, which is missing from standard Markdown.

~~Mistaken text.~~

becomes

Mistaken text.

列表

无序列表,*,+,-,任一种都可以

* Candy.
* Gum.
* Booze.

有序的列表

1. Red
2. Green
3. Blue

链接

This is an [example link](http://example.com/ "With a Title").

(GFM)

GFM will autolink standard URLs, so if you want to link to a URL (instead of setting link text)

图片

![alt text](/path/to/img.jpg "Title")

代码

两种方式,

反引号, 注意不是一般的引号,

I strongly recommend against using any `<blink>` tags.

区块, 每行缩进 4 个空格或是一个 tab, 该区块会默认被认为是代码

 

(GFM)

每行增加4空格或tab, 很麻烦, GFM提高``` …… ```, 来标注代码段

```
function test() {
  console.log("notice the blank line before this function?");
}
```

并且GFM提供Syntax highlighting, 只需要在```后面增加语言名the languages YAML file 

```ruby
require 'redcarpet'
markdown = Redcarpet.new("Hello World!")
puts markdown.to_html
```

Task Lists (GFM)

Further, lists can be turned into Task Lists by prefacing list items with [ ] or [x] (incomplete or complete, respectively).

- [x] @mentions, #refs, [links](), **formatting**, and <del>tags</del> supported 
- [x] list syntax required (any unordered or ordered list supported) 
- [x] this is a complete item 
- [ ] this is an incomplete item

一些特性(GFM)

1. 在github上选中一段文字, 然后按'r' 
会自动跳转到comment, 并将之前选中的这段文字copy作为quoting

2. 输入@, 会自动的bring up a list of people or teams on a project

3. 输入:, 自动弹出表情list, :dog会是小狗...

4. 输入#, 会自动弹出list of Issue and Pull Request suggestions
