How do add pages on menus?
Add the page to the menu. Think about where would you like to display the page: in header or footer?

Second step, choose navigation and add pages to your menu under "Menus":
Lets take example "Header" and click "New Link" (upper right corner) add, for example, 4 links under there (Home, Blog, About Us, Products):

Enter your Link details:

Link Name - as you want to do be shown for your clients
Link Parent - if you want to make page as a sub-menu.
Link Type - which type of page you want to refer to. In this case “Page”.
Entity Name - choose which page you want to establish. For example, if you have a Page or Collection, then you need to define which entity name it is.
The new page will automatically appear on your header menu at homepage.
