Divi Cloud is a plugin that you can use if you want to use template layouts for your pages. I HIGHLY recommend not installing this until you learn how to create pages from scratch as you will need this knowledge to be able to customise the templates.

Even if you have a plan for your website, these templates can often be worth looking at for inspiration purposes and to show you different things that you can do.

If you do install this plugin you will need to let me know so I can add my licence key for you.
