Add Help Tab

As the method name implies, this can be used to add a help tab to the WordPress Admin Page

Usage

$screen = get_current_screen();
//Check to make sure the $screen object is the one you want to add help to
$args = array(  'title' => 'Demo Help', 'id' => 'demo-help', 'content' => 'Html or text to display');
$screen->add_help_tab( $args );

Using a callback

You can also specify a callback function to use above in place of the 'content' key. The result of $args would look like: 

$args = array(  'title' => 'Demo Help', 'id' => 'demo-help', 'callback' => 'demo_help_content');
function demo_help_content () {
    echo '<p>This is the help content that will be echo'd</p>';
}
