New Person - home assistant release

Let say I wanted to implement the new code for the new “Person” entity

Besides configuring the basic variables, how would I turn that into a picture card?

person:
  - name: Ada
    id: ada6789
    device_trackers:
      - device_tracker.ada
  - name: Stacey
    id: stacey12345
    user_id: 12345678912345678912345678912345
    device_trackers:
      - device_tracker.stacey
      - device_tracker.beacon

I understand what I need to replace, but would I need to implement a Boolean as well?
