A MENU is simply a name for a list of actions to perform or places to visit ... they are URLs that are related in some sense -- exactly how they are related is up to the author of the MENU (and is usually encompassed within the title or name of the MENU).
MENUs can be simple, or complex, large or small, with one or more levels (or nested MENUs). MENUs are extremely simple to create, they are simply HTML unordered lists with each MENU item corresponding to a list item that contains a single HTML link without regard to what that link does.

<li><a href="/contact">Contact Us</a></li>
<li><a href="/kinch-bio">Ego at Work</a></li>
<li><a href="/gatepost">The GATE
Post</a></li>
</ul>)
produces output that typically looks like this:
and each of those links will take you to places within GATE Village. But that is only the beginning...
