Markdown is an easy-to-read, easy-to-write language for formatting plain text. You can use Markdown syntax, along with some additional HTML tags, to format your writing on GitHub, in places like repository READMEs and comments on pull requests and issues. In this guide, you'll learn some advanced formatting features by creating a gist.
Gists let you store or share code snippets and other pieces of information with others on your enterprise. To use formatting features in gists, add a gist file with a
- Navigate to your gist home page,
- Optionally, type a description for the gist, such as "About me."
- In the Filename including extension... field, type
For more information, see "Creating gists."
You can include images in your communication on GitHub. Here, you'll add a responsive image, such as a banner, to the top of your gist.
By using the HTML
<picture> element with the
prefers-color-scheme media feature, you can add an image that changes depending on whether a visitor is using light or dark mode. For more information, see "Managing your theme settings."
Copy and paste the following markup into your
<picture> <source media="(prefers-color-scheme: dark)" srcset="YOUR-DARKMODE-IMAGE"> <source media="(prefers-color-scheme: light)" srcset="YOUR-LIGHTMODE-IMAGE"> <img alt="YOUR-ALT-TEXT" src="YOUR-DEFAULT-IMAGE"> </picture>
Replace the placeholders in the markup with the URLs of your chosen images. Alternatively, to try the feature first, you can copy the URLs from our example below.
YOUR-DARKMODE-IMAGEwith the URL of an image to display for visitors using dark mode.
YOUR-LIGHTMODE-IMAGEwith the URL of an image to display for visitors using light mode.
YOUR-DEFAULT-IMAGEwith the URL of an image to display in case neither of the other images can be matched, for example if the visitor is using a browser that does not support the
To make the image accessible for visitors who are using a screen reader, replace
YOUR-ALT-TEXTwith a description of the image.
To check the image has rendered correctly, click the Preview tab.

You can use Markdown tables to organize information. Here, you'll use a table to introduce yourself by ranking something, such as your most-used programming languages or frameworks, the things you're spending your time learning, or your favorite hobbies. When a table column contains numbers, it's useful to right-align the column by using the syntax
--: below the header row.
Return to the Edit new file tab.
To introduce yourself, two lines below the
</picture>tag, add an
## About meheader and a short paragraph about yourself, like the following.
## About me Hi, I'm Mona. You might recognize me as GitHub's mascot.
Two lines below this paragraph, insert a table by copying and pasting the following markup.
| Rank | THING-TO-RANK | |-----:|---------------| | 1| | | 2| | | 3| |
In the column on the right, replace
THING-TO-RANKwith "Languages," "Hobbies," or anything else, and fill in the column with your list of things.
To check the table has rendered correctly, click the Preview tab.
For more information, see "Organizing information with tables."
To keep your content tidy, you can use the
<details> tag to create an expandible collapsed section.
To create a collapsed section for the table you created, wrap your table in
<details>tags like in the following example.
<details> <summary>My top THINGS-TO-RANK</summary> YOUR TABLE </details>
THINGS-TO-RANKwith whatever you ranked in your table.
Optionally, to make the section display as open by default, add the
openattribute to the
To check the collapsed section has rendered correctly, click the Preview tab.
Markdown has many other options for formatting your content. Here, you'll add a horizontal rule to divide your page and a blockquote to format your favorite quote.
At the bottom of your file, two lines below the
</details>tag, add a horizontal rule by typing three or more dashes.
---line, add a quote by typing markup like the following.
QUOTEwith a quote of your choice. Alternatively, copy the quote from our example below.
To check everything has rendered correctly, click the Preview tab.

You can use HTML comment syntax to add a comment that will be hidden in the output. Here, you'll add a comment to remind yourself to update your gist later.
Two lines below the
## About meheader, insert a comment by using the following markup.
<!-- COMMENT -->
COMMENTwith a "to-do" item you remind yourself to do something later (for example, to add more items to the table).
To check your comment is hidden in the output, click the Preview tab.
## About me <!-- TO DO: add more details about me later -->
