A simple WordPress plugin that adds a gist shortcode for getting a single Gist and the files within. It uses the Gist V3 API. Has the option for authentication via Personal Access Token.
Usage 
Get a Gist using a WordPress shortcode: <code>[gist id=00000000 file=file-name.php]</code>
The Gist will return as plain text. I recommend using WordPress plugin Syntaxhighlighter Evolved to highlight the Gist. See below for details.
Visit [Get Gist on Github](http://https://github.com/kopepasah/get-gist “Get Gist”) for more options and information.
