header.php access

I’m using Gridiculous. I saw on another forum post how to put a home page link on my nav bar. It called for altering the code in the header.php. I can’t seem to find that. I only access the header picture, no code. I’m trying to go live by tomorrow and I need that to work or else no one can get back to my blog post. The following was the fix for someone many years ago using a different theme
Would I use the same and if so, how do I get to my header.php?

thank you,

In your header.php, look for …

<div id="naviation"

This DIV holds your nav bar, once you find that you should see something not far below that looks similiar to this…

<ul>
<?php wp_list_pages(); ?>
</ul>

Change it to….

<ul>
<li><a>/">Home</a></li>
<?php wp_list_pages(); ?>
</ul>
