For more information, see [Autolinked references and URLs](https://docs.github.com/en/get-started/writing-on-github/working-with-advanced-formatting/autolinked-references-and-urls). + +## Section links + +You can link directly to any section that has a heading. To view the automatically generated anchor in a rendered file, hover over the section heading to expose the icon and click the icon to display the anchor in your browser. + +![Screenshot of a README for a repository. To the left of a section heading, a link icon is outlined in dark orange.](https://docs.github.com/assets/images/help/repository/readme-links.png) + +If you need to determine the anchor for a heading in a file you are editing, you can use the following basic rules: + +* Letters are converted to lower-case. +* Spaces are replaced by hyphens (`-`). Any other whitespace or punctuation characters are removed. +* Leading and trailing whitespace are removed. +* Markup formatting is removed, leaving only the contents (for example, `_italics_` becomes `italics`). +* If the automatically generated anchor for a heading is identical to an earlier anchor in the same document, a unique identifier is generated by appending a hyphen and an auto-incrementing integer. + +For more detailed information on the requirements of URI fragments, see [RFC 3986: Uniform Resource Identifier (URI): Generic Syntax, Section 3.5](https://www.rfc-editor.org/rfc/rfc3986#section-3.5). + +The code block below demonstrates the basic rules used to generate anchors from headings in rendered content. + +```markdown +# Example headings + +## Sample Section + +## This'll be a _Helpful_ Section About the Greek Letter Θ! +A heading containing characters not allowed in fragments, UTF-8 characters, two consecutive spaces between the first and second words, and formatting. + +## This heading is not unique in the file + +TEXT 1 + +## This heading is not unique in the file + +TEXT 2 + +# Links to the example headings above + +Link to the sample section: [Link Text](#sample-section). + +Link to the helpful section: [Link Text](#thisll-be-a-helpful-section-about-the-greek-letter-Θ). + +Link to the first non-unique section: [Link Text](#this-heading-is-not-unique-in-the-file). + +Link to the second non-unique section: [Link Text](#this-heading-is-not-unique-in-the-file-1). +``` + +> \[!NOTE] +> If you edit a heading, or if you change the order of headings with "identical" anchors, you will also need to update any links to those headings as the anchors will change. + +## Relative links + +You can define relative links and image paths in your rendered files to help readers navigate to other files in your repository. + +A relative link is a link that is relative to the current file. For example, if you have a README file in root of your repository, and you have another file in *docs/CONTRIBUTING.md*, the relative link to *CONTRIBUTING.md* in your README might look like this: + +```text +[Contribution guidelines for this project](docs/CONTRIBUTING.md) +``` + +GitHub will automatically transform your relative link or image path based on whatever branch you're currently on, so that the link or path always works. The path of the link will be relative to the current file. Links starting with `/` will be relative to the repository root. You can use all relative link operands, such as `./` and `../`. + +Your link text should be on a single line. The example below will not work. + +```markdown +[Contribution +guidelines for this project](docs/CONTRIBUTING.md) +``` + +Relative links are easier for users who clone your repository. Absolute links may not work in clones of your repository - we recommend using relative links to refer to other files within your repository. + +## Custom anchors + +You can use standard HTML anchor tags (``) to create navigation anchor points for any location in the document. To avoid ambiguous references, use a unique naming scheme for anchor tags, such as adding a prefix to the `name` attribute value. + +> \[!NOTE] +> Custom anchors will not be included in the document outline/Table of Contents. + +You can link to a custom anchor using the value of the `name` attribute you gave the anchor. The syntax is exactly the same as when you link to an anchor that is automatically generated for a heading. + +For example: + +```markdown +# Section Heading + +Some body text of this section. + + +Some text I want to provide a direct link to, but which doesn't have its own heading. + +(… more content…) + +[A link to that custom anchor](#my-custom-anchor-point) +``` + +> \[!TIP] +> Custom anchors are not considered by the automatic naming and numbering behavior of automatic heading links. + +## Line breaks + +If you're writing in issues, pull requests, or discussions in a repository, GitHub will render a line break automatically: + +```markdown +This example +Will span two lines +``` + +However, if you are writing in an .md file, the example above would render on one line without a line break. To create a line break in an .md file, you will need to include one of the following: + +* Include two spaces at the end of the first line. + 
+  This example  
+  Will span two lines
+
+ +* Include a backslash at the end of the first line. + + ```markdown + This example\ + Will span two lines + ``` + +* Include an HTML single line break tag at the end of the first line. + + ```markdown + This example
+ Will span two lines + ``` + +If you leave a blank line between two lines, both .md files and Markdown in issues, pull requests, and discussions will render the two lines separated by the blank line: + +```markdown +This example + +Will have a blank line separating both lines +``` + +## Images + +You can display an image by adding ! and wrapping the alt text in `[ ]`. Alt text is a short text equivalent of the information in the image. Then, wrap the link for the image in parentheses `()`. + +`![Screenshot of a comment on a GitHub issue showing an image, added in the Markdown, of an Octocat smiling and raising a tentacle.](https://docs.github.comhttps://myoctocat.com/assets/images/base-octocat.svg)` + +![Screenshot of a comment on a GitHub issue showing an image, added in the Markdown, of an Octocat smiling and raising a tentacle.](https://docs.github.com/assets/images/help/writing/image-rendered.png) + +GitHub supports embedding images into your issues, pull requests, discussions, comments and `.md` files.

John Quincy Adams +``` + +![Screenshot of rendered GitHub Markdown showing a numbered list of the names of the fourth, fifth, and sixth American presidents.](https://docs.github.com/assets/images/help/writing/ordered-list-rendered.png) + +### 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 on GitHub or a text editor that uses a monospaced font, like [Visual Studio Code](https://code.visualstudio.com/), 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. + +```markdown +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. + +![Screenshot of Markdown in Visual Studio Code showing indentation of nested numbered lines and bullets.](https://docs.github.com/assets/images/help/writing/nested-list-alignment.png) + +![Screenshot of rendered GitHub Markdown showing a numbered item followed by nested bullets at two different levels of nesting.](https://docs.github.com/assets/images/help/writing/nested-list-example-1.png) + +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`. + +```markdown +100. First list item + - First nested list item +``` + +![Screenshot of rendered GitHub Markdown showing a numbered item prefaced by the number 100 followed by a bulleted item nested one level.](https://docs.github.com/assets/images/help/writing/nested-list-example-3.png) + +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 at least two more characters (nine spaces minimum). + +```markdown +100. First list item + - First nested list item + - Second nested list item +``` + +![Screenshot of rendered GitHub Markdown showing a numbered item prefaced by the number 100 followed by bullets at two different levels of nesting.](https://docs.github.com/assets/images/help/writing/nested-list-example-2.png) + +For more examples, see the [GitHub Flavored Markdown Spec](https://github.github.com/gfm/#example-265). + +## Task lists + +To create a task list, preface list items with a hyphen and space followed by `[ ]`.
