 * Whenever your module invokes a hook you should document the use-case, and
 * parameters for that hook in a {MODULE_NAME}.api.php file. The standard is to
 * create a docblock where the first line is a summary starting with an
 * imperative verb. Followed by a more detailed explanation of when the hook
 * is triggered and documentation for any parameters.
 *
 * The body of the function should contain a functional example.
