How to verify ownership on Google Webmaster Tools ?

Hello,

I have built my website with opencart and was wondering how I can verify my site on Google Webmaster Tools?I have created the account on Google Analytics but I failed to verify the site with the option "Link to your Google Analytics account". So i tried to use the option "Add a meta tag to your site's home page". Would you please let me know how to do that ?

Please help

I didn't find the right solution from the internet.
