If the parent doesn't have a Windows Phone, that's fine—you can still set up My Family. If the parent doesn't have a Microsoft account, you'll have a chance to create one.
Kung walang Windows Phone ang magulang, ayos lang iyon—maaari mo pa ring i-set up ang Aking Pamilya. Kung walang account sa Microsoft ang magulang, magkakaroon ka ng pagkakataong gumawa ng isa.
