How duplicate a page ?

I have created the homepage of my website. Now I would like create the "about us page" and "contact page".

How can I duplicate the homepage without create a new page from zero ?

In the Design section (bottom right), click on Pages, right click over the page you wish to duplicate, click on Duplicate. Then right click over the newly duplicated page, right click, left click on Rename and give it a new name.

On the right side, in the "Design Panel" - "Pages" right-click on the "index.html" and "duplicate"
