Markdown is a lightweight markup language that lets authors focus on writing without paying attention to style.

## title

When writing with Markdown, you only need to add 『#』 in front of the text to create a first-level title. Similarly, to create a secondary title, a third-level title, etc., only need to increase the number of 『#』, Markdown supports a total of six titles. As follows:

## Reference

The Markdown tag block reference is similar to the email referenced by 『>』, just add 『>』 at the top of the first line of the entire paragraph.
Block references can be nested, as long as different numbers of 『>』 are added according to the level:

example

This is the first level reference.

This is the second level reference.

Now go back to the first level reference.

Other Markdown syntaxes, including titles, lists, code blocks, etc., can also be used within the referenced block:

example

1. This is the first line of list items.
2. This is the second line of list items.

Give some example code:

return shell_exec(echo $input |$markdown_script);

## List

The list item tag is usually placed on the far left, and the item tag is followed by a character space.
Unordered list: use an asterisk, plus or minus sign as a list mark

example

• Red
• Green
• Blue

Ordered list: use numbers followed by an English period

1. Red
2. Green
3. Blue
If you want to put a reference in the list item, then 『>』 needs to be indented:

example

• My Porject:

code1
code2
code3

Agent list: Indicates whether the list is checked or not (note: there must be spaces before and after [ ])

example

• not selected
• tick

## Code

Just wrap your code block between “, you don’t need to mark the code block by endless indentation. In a fenced code block, you can specify an optional language identifier, then we can Enable syntax coloring for it. For example, this can be used to color a piece of Ruby code:

ruby
require ‘redcarpet’
markdown = Redcarpet.new(“Hello World!”)
puts markdown.to_html
`

example

## Emphasize

In Markdown, you can use * and _ to indicate italics and bold.
Italic:

Coding
Coding

Bold:

Coding

Square brackets show the description, the URL is displayed in parentheses, and Markdown automatically converts it into a link, for example:

example
blog

## form

In Markdown, you can make a table, for example:

example

Content Cell Content Cell Content Cell
Content Cell Content Cell Content Cell

Or you can align the contents of the table and center the content, for example:

Left Center Right
Left Center Right

## Dividing line

In Markdown, you can create split lines using more than 3 『-』 symbols, for example:

123

456

## image

Markdown uses a link-like syntax to insert images, in two forms: inline and reference.
The inline picture syntax is as follows:

That is:

• An exclamation mark 『!』
• Next a square bracket with an alternate text for the image
• Then there is an ordinary parenthesis, which is the URL of the image. Finally, you can enclose it in quotation marks and add the optional 『title』 text.
The quote picture syntax is as follows:

『id』 is the name of the image reference. The image reference uses the same syntax defined by the link:
