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
When you use two or more headings, GitHub automatically generates a table of contents which you can access by clicking within the file header. Each heading title is listed in the table of contents and you can click a title to navigate to the selected section.
You can indicate emphasis with bold, italic, strikethrough, subscript, or superscript text in comment fields and
|Bold||Command+B (Mac) or Ctrl+B (Windows/Linux)||This is bold text|
|Italic||Command+I (Mac) or Ctrl+I (Windows/Linux)||This text is italicized|
|Bold and nested italic||This text is extremely important|
|All bold and italic||All this text is important|
|Subscript||This is a subscript text|
|Superscript||This is a superscript text|
You can quote text with a >.
Text that is not a quote > Text that is a quote
Tip: When viewing a conversation, you can automatically quote text in a comment by highlighting the text, then typing R. You can quote an entire comment by clicking , then Quote reply. For more information about keyboard shortcuts, see "Keyboard shortcuts."
You can call out code or a command within a sentence with single backticks. The text within the backticks will not be formatted. You can also press the Command+E (Mac) or Ctrl+E (Windows/Linux) keyboard shortcut to insert the backticks for a code block within a line of Markdown.
Use `git status` to list all new or modified files that haven't yet been committed.
To format code or text into its own distinct block, use triple backticks.
Some basic Git commands are: ``` git status git add git commit ```
For more information, see "Creating and highlighting code blocks."
如果经常编辑代码片段和表，则可能受益于在 GitHub 上启用对所有注释字段采用固定宽度字体。 有关详细信息，请参阅“在编辑器中启用固定宽度字体”。
In issues, pull requests, and discussions, you can call out colors within a sentence by using backticks. A supported color model within backticks will display a visualization of the color.
The background color should be `#ffffff` for light mode and `#0d1117` for dark mode.
Here are the currently supported color models.
- A supported color model cannot have any leading or trailing spaces within the backticks.
- The visualization of the color is only supported in issues, pull requests, and discussions.
You can create an inline link by wrapping link text in brackets
[ ], and then wrapping the URL in parentheses
( ). You can also use the keyboard shortcut Command+K to create a link. When you have text selected, you can paste a URL from your clipboard to automatically create a link from the selection.
You can also create a Markdown hyperlink by highlighting the text and using the keyboard shortcut Command+V. If you'd like to replace the text with the link, use the keyboard shortcut Command+Shift+V.

Tip: GitHub automatically creates links when valid URLs are written in a comment. For more information, see "Autolinked references and URLs."
相对链接是相对于当前文件的链接。 例如，如果在仓库根目录下有一个自述文件，而在 docs/CONTRIBUTING.md 中有另一个文件，则自述文件中的 CONTRIBUTING.md 的相关链接如下所示 ：
[Contribution guidelines for this project](docs/CONTRIBUTING.md)
GitHub 将根据您当前使用的分支自动转换相对链接或图像路径，从而使链接或路径始终有效。 链接的路径将相对于当前文件。 以
/ 开头的链接将相对于存储库根目录。 可使用所有相对链接操作数，例如
相对链接更便于用户克隆仓库。 绝对链接可能无法用于仓库的克隆 - 建议使用相对链接引用仓库中的其他文件。
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)
GitHub supports embedding images into your issues, pull requests, discussions, comments and
.md files. You can display an image from your repository, add a link to an online image, or upload an image. For more information, see "Uploading assets."
Tip: When you want to display an image which is in your repository, you should use relative links instead of absolute links.
Here are some examples for using relative links to display an image.
|In a |
|In a |
|In issues, pull requests and comments of the repository|
|In a |
|In issues, pull requests and comments of another repository|
Note: The last two relative links in the table above will work for images in a private repository only if the viewer has at least read access to the private repository which contains these images.
For more information, see "Relative Links."
You can specify the theme an image is displayed for in Markdown by using the HTML
<picture> element in combination with the
prefers-color-scheme media feature. We distinguish between light and dark color modes, so there are two options available. You can use these options to display images optimized for dark or light backgrounds. This is particularly helpful for transparent PNG images.
For example, the following code displays a sun image for light themes and a moon for dark themes:
<picture> <source media="(prefers-color-scheme: dark)" srcset="https://user-images.githubusercontent.com/25423296/163456776-7f95b81a-f1ed-45f7-b7ab-8fa810d529fa.png"> <source media="(prefers-color-scheme: light)" srcset="https://user-images.githubusercontent.com/25423296/163456779-a8556205-d0a5-45e2-ac17-42d089e3c3f8.png"> <img alt="Shows an illustrated sun in light mode and a moon with stars in dark mode." src="https://user-images.githubusercontent.com/25423296/163456779-a8556205-d0a5-45e2-ac17-42d089e3c3f8.png"> </picture>
The old method of specifying images based on the theme, by using a fragment appended to the URL (
#gh-light-mode-only), is deprecated and will be removed in favor of the new method described above.
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
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 on GitHub or a text editor that uses a monospaced font, like Visual Studio Code, 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
Note: In the web-based editor, you can indent or dedent one or more lines of text by first highlighting the desired lines and then using Tab or Shift+Tab respectively.
To create a nested list in the comment editor on GitHub, which doesn't use a monospaced font, you can look at the list item immediately above the nested list and count the number of characters that appear before the content of the item. Then type that number of space characters in front of the 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

You can mention a person or team on GitHub by typing @ plus their username or team name. This will trigger a notification and bring their attention to the conversation. People will also receive a notification if you edit a comment to mention their username or team name. For more information about notifications, see "About notifications."
Note: A person will only be notified about a mention if the person has read access to the repository and, if the repository is owned by an organization, the person is a member of the organization.
@github/support What do you think about these updates?
When you mention a parent team, members of its child teams also receive notifications, simplifying communication with multiple groups of people. For more information, see "About teams."
Typing an @ symbol will bring up a list of people or teams on a project. The list filters as you type, so once you find the name of the person or team you are looking for, you can use the arrow keys to select it and press either tab or enter to complete the name. For teams, enter the @organization/team-name and all members of that team will get subscribed to the conversation.
The autocomplete results are restricted to repository collaborators and any other participants on the thread.
You can bring up a list of suggested issues and pull requests within the repository by typing #. Type the issue or pull request number or title to filter the list, and then press either tab or enter to complete the highlighted result.

You can create a new paragraph by leaving a blank line between lines of text.
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.
Footnotes are not supported in wikis.
You can tell GitHub to hide content from the rendered Markdown by placing the content in an HTML comment.
<!-- This content will not appear in the rendered Markdown -->
You can tell GitHub to ignore (or escape) Markdown formatting by using \ before the Markdown character.
Let's rename \*our-new-project\* to \*our-old-project\*.
