What is Markdown?

Markdown is a way to style text on the web. You control the display of the document; formatting words as bold or italic, adding images, and creating lists are just a few of the things we can do with Markdown. Mostly, Markdown is just regular text with a few non-alphabetic characters thrown in, like # or *.

You can use Markdown most places around GitHub:

  • Comments in Issues and Pull Requests
  • Files with the .md or .markdown extension

For more information, see “Writing on GitHub” in the GitHub Help.


It's very easy to make some words bold and other words italic with Markdown. You can even link to Google!

Syntax guide

Here’s an overview of Markdown syntax that you can use anywhere on or in your own text files.

Inline code

GitHub Flavored Markdown uses its own version of the Markdown syntax that provides an additional set of useful features, many of which make it easier to work with content on

Note that some features of GitHub Flavored Markdown are only available in the descriptions and comments of Issues and Pull Requests. These include @mentions as well as references to SHA-1 hashes, Issues, and Pull Requests. Task Lists are also available in Gist comments and in Gist Markdown files.

Syntax highlighting

Here’s an example of how you can use syntax highlighting with GitHub Flavored Markdown:

You can also simply indent your code by four spaces:

Here’s an example of Python code without syntax highlighting:

Task Lists

If you include a task list in the first comment of an Issue, you will get a handy progress indicator in your issue list. It also works in Pull Requests!


You can create tables by assembling a list of words and dividing them with hyphens - (for the first row), and then separating each column with a pipe :

Would become:

First HeaderSecond Header
Content from cell 1Content from cell 2
Content in the first columnContent in the second column

SHA references

Any reference to a commit’s SHA-1 hash will be automatically converted into a link to that commit on GitHub.

Issue references within a repository

Any number that refers to an Issue or Pull Request will be automatically converted into a link.

Username @mentions

Typing an @ symbol, followed by a username, will notify that person to come and view the comment. This is called an “@mention”, because you’re mentioning the individual. You can also @mention teams within an organization.

Automatic linking for URLs

Any URL (like will be automatically converted into a clickable link.


Any word wrapped with two tildes (like ~~this~~) will appear crossed out.


GitHub supports emoji!

In MarkdownInline Images may be displayed in using the exclamation point ! followed by a bracketed [Alt Text] followed by a relative URL enclosed in a single set of parenthesis (..), as follows:

Break It Down

Place a “bracket” symbol [ in front of and at the end of ] the Alt Text part of your Image Url when crafting Image Url using GitHub Flavored Markdown, as follows:

Alt Text

Recall from Html how Alt Text is required just in case your image file does not render in the client browser window.

Especially for screen readers that do not rely on visual information, having an idea of what type of image you are attempting to render keeps the flow of information moving.

Next, append and encircle the relative path to the image file with a single set of parenthesis as shown in the following code block …

The Assets Subdirectory

Markdown Github Online Editor

The Assets sub-folder sits in the root of your docs folder.

Recall that all of your Git Hub Pages are served from the docs folder.

Specifically, from the pages subdirectory within the docs folder.

The Assets Subfolder

The Assets sub-folder is further split into three more folders …

  1. css

  2. ico, and

  3. img

Note. The css folder holds the style sheet ( .scss ) for the repo, the ico folder holds images of less than 100 px in width, and the img folder holds image files of 100 px or more in width.

The Exclamation Point

Finally, to enable the fetching and rendering of your subject image in Markdown, prepend the Alt Text of your image with an exclamation point ! right before the first bracket [ at the beginning of your image statement, as follows:

Going Live

Da Rule

Inline Images may be displayed using the exclamation point ! followed by a bracketed [Alt Text] followed by a relative pathway to the image file enclosed in a single set of parenthesis (..).

Base Dimensions

Here, we are going to use an original ( .xcf ) file that has been exported from GIMP as a ( .psd ) of dimensions 725 px X 725 px X 96 dpi.

Import to AI

Next, the resultant ( .psd ) file is imported into Adobe Illustrator, or AI via simple ‘File Open’.

Once inside AI, the ( .psd ) file is then “save as” an ( .svg ).
