这是一篇讲解如何正确使用 Markdown 的排版示例，学会这个很有必要，能让你的文章有更佳清晰的排版。

引用文本：Markdown is a text formatting syntax inspired

语法指导

普通内容

这段内容展示了在内容里面一些排版格式，比如：

加粗 - **加粗**
倾斜 - *倾斜*
~~删除线~~ - ~~删除线~~
Code 标记 - `Code 标记`
超级链接 - [超级链接](https://hacpai.com)
username@gmail.com - [username@gmail.com](mailto:username@gmail.com)

提及用户

@Vanessa 通过 @User 可以在内容中提及用户，被提及的用户将会收到系统通知。

NOTE:

@用户名之后需要有一个空格

新手没有艾特的功能权限

大标题 - Heading 3

你可以选择使用 H1 至 H6，使用 ##(N) 打头。建议帖子或回帖中的顶级标题使用 Heading 3，不要使用 1 或 2，因为 1 是系统站点级，2 是帖子标题级。

NOTE: 别忘了 # 后面需要有空格！

Heading 4

Heading 5

Heading 6

代码块

普通

*emphasize*    **strong**
_emphasize_    __strong__
var a = 1

语法高亮支持

如果在 ``` 后面跟随语言名称，可以有语法高亮的效果哦，比如:

演示 Go 代码高亮

package main

import "fmt"

func main() {
	fmt.Println("Hello, 世界")
}

演示 Java 高亮

public class HelloWorld {

    public static void main(String[] args) {
        System.out.println("Hello World!");
    }

}

Tip: 语言名称支持下面这些: ruby, python, js, html, erb, css, coffee, bash, json, yml, xml ...

段落

空行可以将内容进行分段，便于阅读。（这是第一段）

使用空行在 Markdown 排版中相当重要。（这是第二段）

数学公式

$$a^2 + b^2 = \color{red}c^2$$

    c1-->a2
    subgraph one
    a1-->a2
    end
    subgraph two

    end
    subgraph three
    c1-->c2
    end
