How do I rename a new folder on home screen

[Meinbeast19]

Created a folder using menu > add> folders to place my favorite contacts into. My question is how do I now name this folder? The default folder names are
"starred", "phones" ,"folder" etc.. I would need to rename to folders family. work, friends etc......has anyone done this?
