In your WordPress dashboard, navigate to Pages, and then click Add New.

Give your page a title and then add a Parent Page under the Page Attributes section. This allows for more organization of your site.

Then, switch your editor to the Page Builder tab. This will launch the Visual Page Editor and allow you to use Beaver Builder to add modules, rows, and columns to the page.

Use the Visual Page Editor to edit the page content.  Read more here.

Click Publish when done.
