# On-call schedules

- [Introduction to On-call schedules](https://docs.spike.sh/oncall-schedules/introduction-to-on-call-schedules.md): What is On-call? What are schedules? Get started with the basics.
- [Create On-call schedule](https://docs.spike.sh/oncall-schedules/create-on-call-schedule.md): Set up an on-call schedule to define who's on-call and when across your team.
- [Slots in schedules](https://docs.spike.sh/oncall-schedules/introduction-to-slots-in-schedules.md): Slots restrict on-call coverage to specific hours or days, so team members aren't on-call around the clock.
- [Layers in on-call schedules](https://docs.spike.sh/oncall-schedules/introduction-to-layers-in-on-call-schedules.md): Layers let you stack multiple on-call configurations within a single schedule. When two layers overlap, the higher-numbered layer takes over.
- [Override an on-call](https://docs.spike.sh/oncall-schedules/override-an-on-call.md): On-call overrides assign temporary coverage for a shift without changing the underlying schedule.
