# Concepts

## Docs

- [Groups](https://developer.vitablehealth.com/embedded_care/concepts/groups.md): What a group is in Vitable, how it relates to plans and members, and how its lifecycle works.
- [Member Lifecycle](https://developer.vitablehealth.com/embedded_care/concepts/member-lifecycle.md): What happens to a member from the moment they appear in a sync — provisioning, authentication, plan subscription, removal, and re-add.
- [Member Sync](https://developer.vitablehealth.com/embedded_care/concepts/member-sync.md): How member sync works under the hood — the replacement model, reference matching, async processing, and how to read the results.
