README

This repo is a translation of https://github.com/guodongxiaren/README. Thanks a lot for the original author's effort. This file is used to demonstrate the markdown syntax for writing README files. The markdown syntax is extended on Github, which is called GitHub Flavored Markdown, i.e. GFM. GFM is widely used on GitHub. Issues and wiki also support GFM syntax.

Headers

This is an h1 tag

This is an h2 tag

This is an h3 tag

This is an h4 tag

This is an h5 tag

This is an h6 tag

Texts

Normal text

This is a example of normal text.

Single-line text

Hello, world!

Add 1 tab or 4 spaces at the beginning of the line.

Multi-line text

Syntax 1

Add 1 tab or 4 spaces at the beginning of several lines of text.

Sons of Gondor,
of Rohan,
my brothers!

Syntax 2

Use three backticks:

Sons of Gondor,
of Rohan,
my brothers!

This syntax can also be used for code highlighting，See Fenced code blocks.

Text highlighting

Using a pair of backquotes. Syntax：

`linux` `ubuntu` `socket` `epoll` 

Look like: linux ubuntu socket epoll

Also suitable for making tags for articles.

Wrap

Directly inputing return cannot wrap.
You may add two spaces after the previous line of text. Then the text of the next line is wrapped.

You may also add a blank line directly to the two lines of text.

This operation can also be used to wrap, except the line spacing is a bit large.

Emphasis and strikethrough

Syntax	Look like
*Italic1*	Italic1
_Italic2_	Italic2
**Bold1**	Bold1
__Bold2__	Bold2
This is a ~~strikethrough~~	This is a strikethrough
***Italic plus bold1***	Italic plus bold1
___Italic plus bold2___	Italic plus bold2
***~~Italic, bold, and strikethrough1~~***	Italic, bold, and strikethrough1
~~***Italic, bold, and strikethrough2***~~	Italic, bold, and strikethrough2

Italic, bold, strikethrough is able to be used together.

Images

Basic syntax：

![alt](URL title)

alt and title are corresponding to the alt and title attributes in the HTML (all can be omitted)：

• alt indicates the replacement text when the image fails to display
• title indicates the text to display when the mouse hovers over the image (note that it should be quoted here)

The URL is the url address of the image. If you refer to the image in this repository, you can use the relative path directly. If you refer to the images in other github repositories, you should pay attention to the format, ie: repository address/raw/branch_name/image_path , e.g.

https://github.com/username/reponame/raw/master/folder/imagename.gif

#	Syntax	Look like
1	
2	![][foryou]

Note that the syntax of Example 2 uses the form of the link labels, which has been described in the Link section.

foryou is defined at the end of the page like this:

[foryou]:https://github.com/guodongxiaren/ImageCache/raw/master/Logo/foryou.gif

Link

Links to external URLs

#	Syntax	Look like
1	[My blog](http://www.cnblogs.com/yaoyaoliu "Hover display")	My blog](http://www.cnblogs.com/yaoyaoliu "Hover display")
2	[My GitHub][GitHubLink]	My GitHub

This syntax consists of two parts:：

• The label in [ ] (in this case is GitHubLink). It can be a combination of numbers, letters, etc.
• The actual URL.

You may define your link label anywhere in the document.

Links to the URLs in this repository

Syntax	Look like
[Example document](/example/example.md)	Example document
[example](./example)	example

Image links

The essence of adding links to images is mixing image display syntax with the normal link syntax. In the normal link, [ ] is the text to be displayed inside the link, and the image link [ ] is the image to be displayed. It's ok to mix the two syntaxes directly, but it's awkward, so we can use the form of the link label.

#	Syntax	Look like
1	[![weibo-logo]](http://weibo.com/)
2	[][zhihu]
3	[![csdn-logo]][csdn]

As the image and the link both support link label, the image link can be very simple (see Example 3). Note that the text displayed when the mouse hovers there is the title of the image, not the title of the link.

All the link labels in the documents is placed at the end of the document.

Anchor

In fact, each title is an anchor, similar to the HTML anchor (#), e.g.

Syntax	Look like
[Back to top](#readme)	Back to top

Note that all the letters in the title are converted to lowercase letters.

Lists

Unordered

Syntax

* First name: Yaoyao
- Last name: Liu
* Title: Mr.

Look like

• First name: Yaoyao

• Last name: Liu

• Title: Mr.

Multi-level unordered

Syntax

* Python
    * Tensorflow
        * slim

Look like

• Python
  • Tensorflow
    • slim

Ordered

Syntax

Just add a dot and a space after the number. However it may not seem obvious enough.

Famous social media:

1. FB
2. IG
3. WeChat

Look like

Multi-level ordered

Like unordered lists, ordered lists also have a multi-level structure.

Syntax

1. First
   1. Second
      1. Third

Look like

1. First
   1. Second
      1. Third

Task Lists

Syntax

- [x] item 1
- [x] item 2
- [x] item 3
- [ ] itme 4
- [ ] item 5
- [ ] item 6

Look like

• item 1
• item 2
• item 3
• itme 4
• item 5
• item 6

Tip:

You may use this syntax in GitHub's issue to check or uncheck the checkbox in real time without having to modify the original version of the issue.

Blockquotes

Syntax

As Grace Hopper said:
> I’ve always been more interested
> in the future than in the past.

Look like

As Grace Hopper said:

I’ve always been more interested in the future than in the past.

Multi-level blockquotes

Syntax

> Asia
>> China
>>> Beijing
>>>> Haidian
>>>>> Tsinghua

Look like

Asia

China

Beijing

Haidian

Tsinghua

Fenced code blocks

Syntax

With GFM you can wrap your code with three back quotes to create a code block without the leading spaces. Add annoptional language identifier and your code will get syntax highlighting.

Look like

public static void main(String[]args){} //Java

int main(int argc, char *argv[]) //C

echo "hello GitHub" #Bash

document.getElementById("myH1").innerHTML="Welcome to my Homepage"; //javascipt

string &operator+(const string& A,const string& B) //cpp

Tables

First Header	Second Header
Content cell 1	Content cell 2
Content column 1	Content column 2

Align

You may specify alignment like this:

Align left	Centered	Align right
col 3 is	some wordy text	$1600
col 2 is	centered	$12
zebra stripes	are neat	$1

Mix with other syntax

Most GFM syntax can be applied in the contents of the table cell, e.g.

Use strikethrough, italic, etc.

Name	Content
Help	Display the help window.
Close	Closes a window

Embed an image (link) in the table

Img	Text
	Baidu

Emoji

GFM syntax supports adding emojis, and entering different symbol codes (characters surrounded by two colons) can display different emoticons.

e.g.:blush:，look like:blush:。

You may check the codes for different emojis using this link: http://www.emoji-cheat-sheet.com。

But this page is loaded very slowly every time. So I sorted it into this repo, you can view it directly here.emoji。

diff syntax

In the version control system, the function of diff is indispensable, i.e., the addition and deletion of a file content is displayed. The diff effect that can be displayed in GFM. Green is for new, while red is for deleted.

Syntax

The syntax is similar to code fenced code blocks, except that the diff is written after the three backticks. And in the content, the beginning of + indicates the addition, and the beginning of - indicates the deletion.

Look like

+ Hello world!
- This is useless.
