If the cube "Websites" cube is not on your home screen, see How can I add a cube to my home screen?
Open the "Websites"cube.
If you click on a website in the list, this website will open on a new tab in your browser. Or if you are using the Cubigo app in a new window, the "Back" button on the top left will remain on the screen.
If you want to add the website to your home screen, click the green "home screen" button.
The website has now been added to your home screen as a "cube".
