From the CNN piece:
The new “Families” page — located at apple.com/families — is an attempt to help parents understand and use all the features that are already floating around on Apple devices. Many parents may not know that they have the power to track their children’s location, monitor and limit their purchases, and filter what content they can see on their devices.
It also covers privacy, health related settings like sleep mode, sharing between family members, and the use of Apple devices in education.
The company also updated its support page for parental controls.
