The backtick (also known as the grave accent or backquote) is used to start a code section in Markdown, because of this it’s a little tricky to include it without triggering the code formatting in a page. This snippet demonstrates the various ways of displaying a backtick.

To include a non-code formatted backtick it can be added by escaping it with a \ .
1 | \` |
# Backtick within code
Wrapping inline code blocks in double backticks instead of single backticks allow a backtick to be used.
1 | `` ` `` |
such as `` ` this is a test ` `` will be `this is a test`
Alternatively a code block can be used, this will wrap everything in a <pre> however. To do this either indent 4 spaces to start a code block
1 | ` |
or use fenced code blocks if supported
1 | ``` |
