# OpenCluster

> Set up OpenCluster, connect incident data, and investigate alerts.

## Docs

- [OpenCluster](https://docs.open-cluster.io/index.md): Investigate incidents across the systems you already use, with cited findings and read-only access.
- [Quickstart](https://docs.open-cluster.io/getting-started/quickstart.md): Connect Alertmanager and Slack, deliver an alert, and run your first useful investigation.
- [How investigations work](https://docs.open-cluster.io/getting-started/how-investigations-work.md): See how an incident becomes a bounded, adaptive investigation across connected systems.
- [Investigate an incident](https://docs.open-cluster.io/investigations/investigate-an-incident.md): Start an investigation, monitor its progress, and decide what to do with the result.
- [Understand findings and citations](https://docs.open-cluster.io/investigations/findings-and-citations.md): Interpret finding types, confidence, citations, unresolved leads, and next steps.
- [Integrations](https://docs.open-cluster.io/integrations/overview.md): Choose systems by the role they play in an OpenCluster investigation.
- [Prometheus Alertmanager](https://docs.open-cluster.io/integrations/alerting/alertmanager.md): Create incidents from authenticated Alertmanager webhook deliveries.
- [Kubernetes](https://docs.open-cluster.io/integrations/infrastructure/kubernetes.md): Give investigations a current, read-only Kubernetes workload inventory through an outbound Relay.
- [Slack](https://docs.open-cluster.io/integrations/collaboration/slack.md): Give investigations read-only access to conversations visible to a connected Slack token.
- [GitHub](https://docs.open-cluster.io/integrations/source-control/github.md): Give investigations read-only access to selected repositories, changes, CI failures, files, and releases.
- [Security model](https://docs.open-cluster.io/security/security-model.md): Understand OpenCluster access boundaries, tenant isolation, read-only behavior, and self-hosted trust boundaries.
- [Credentials and data access](https://docs.open-cluster.io/security/credentials-and-data-access.md): Review how credentials are stored, what each integration can read, and what is sent to model providers.
- [Self-host OpenCluster](https://docs.open-cluster.io/self-hosted/overview.md): Run the OpenCluster control plane with PostgreSQL and expose only the listeners you need.
- [Configuration](https://docs.open-cluster.io/self-hosted/configuration.md): Configure storage, listeners, integrations, investigations, and operational limits.
- [Operations](https://docs.open-cluster.io/self-hosted/operations.md): Monitor health, deploy safely, manage retention, and understand background work.
- [Troubleshooting](https://docs.open-cluster.io/self-hosted/troubleshooting.md): Resolve startup, readiness, integration, Relay, and investigation failures.
