Rename home page in main menu

Hi

Hi!
By default, there are two menus always visible on your screen, the "Main" menu and the "Top" menu. To customize any of them you have to go to the page Appearance => Menus and set the created menu as a main/top menu. Here are the intelligible instructions:

To rename this item you need to create your own menu. Then you will be able to name all the menu items by yourself.
