Click "Make a new folder."

A folder will be created named "New Folder." The name will be selected, highlighted blue, and surrounded by a thin border. This means that if you type something now, the text you type will replace the text in the box beneath the folder.

Type "website." Then press the "Enter" or "Return" key on your keyboard. If all went well, the folder will now be named "website." It will still be highlighted blue, but it won't have the thin border anymore. If you happen to make a mistake; for example clicking somewhere before typing the new name in, which causes the folder to be labeled "New Folder;" simply right-click on the folder. A context menu will appear; select rename and edit the name. Press enter when you have it the way you want it.
