HOME button missing

Hello all, It can't be only me that is missing a HOME button on this theme? Example: If I click on the menu and navigate to one of the categories I have added, once I'm on that page I want to be able to get back to the first landing page of the site. But there is no such option or it it just me who is a total noob(which I am) and there is a simple fix? The site in question is: www.said-belhaj.com Thankful for help, Alexandra
