Markdown 语法

使用 Markdown 语法创建复杂的格式，这里提供了所有 Markdown 语法元素的快速概览

Headings #

To create a heading, add one to six # symbols before your heading text. The number of # you use will determine the size of the heading.

# The largest heading
## The second largest heading
###### The smallest heading

Styling text #

You can indicate emphasis with bold, italic, or strikethrough text in comment fields and .md files.

Quoting text #

You can quote text with a >.

Text that is not a quote

> Text that is a quote

Quoting code #

You can call out code or a command within a sentence with single backticks. The text within the backticks will not be formatted.

Write like this:


    ```markdown
    Code here.
    ```

Links #

You can create an inline link by wrapping link text in brackets [ ], and then wrapping the URL in parentheses ( ).

Images #

You can display an image by adding ! and wrapping the alt text in[ ]. Then wrap the link for the image in parentheses ().

![This is an image](https://myoctocat.com/assets/images/base-octocat.svg)

Tip: When you want to display an image which is in your repository, you should use relative links instead of absolute links.

Lists #

You can make an unordered list by preceding one or more lines of text with - or *.

- George Washington
- John Adams
- Thomas Jefferson

To order your list, precede each line with a number.

1. James Madison
2. James Monroe
3. John Quincy Adams

Nested Lists #

You can create a nested list by indenting one or more list items below another item.

To create a nested list using the web editor a text editor that uses a monospaced font, like Atom, you can align your list visually. Type space characters in front of your nested list item, until the list marker character (- or *) lies directly below the first character of the text in the item above it.

1. First list item
   - First nested list item
     - Second nested list item

In this example, you could add a nested list item under the list item 100. First list item by indenting the nested list item a minimum of five spaces, since there are five characters (100. ) before First list item.

100. First list item
     - First nested list item

You can create multiple levels of nested lists using the same method. For example, because the first nested list item has seven characters (␣␣␣␣␣-␣) before the nested list content First nested list item, you would need to indent the second nested list item by seven spaces.

100. First list item
     - First nested list item
       - Second nested list item

Using emoji #

You can add emoji to your writing by typing :EMOJICODE:.

Typing : will bring up a list of suggested emoji. The list will filter as you type, so once you find the emoji you’re looking for, press Tab or Enter to complete the highlighted result.

Paragraphs #

You can create a new paragraph by leaving a blank line between lines of text.

Footnotes #

You can add footnotes to your content by using this bracket syntax:

Here is a simple footnote[^1].

A footnote can also have multiple lines[^2].  

You can also use words, to fit your writing style more closely[^note].

[^1]: My reference.
[^2]: Every new line should be prefixed with 2 spaces.  
  This allows you to have a footnote with multiple lines.
[^note]:
    Named footnotes will still render with numbers instead of the text but allow easier identification and linking.  
    This footnote also has been made with a different syntax using 4 spaces for new lines.

The footnote will render like this:

Note: The position of a footnote in your Markdown does not influence where the footnote will be rendered. You can write a footnote right after your reference to the footnote, and the footnote will still render at the bottom of the Markdown.
