To create a child theme functions file, I copied the functions.php file from the parent theme folder and dropped it in the child theme folder called nms509. I dropped the following code into appropriate sections of the functions.php file:
<?php
/* Custom code goes below this line. */
/* Custom code goes above this line. */
?>
