+# Rook
+
+Rook is an open-source cloud-native storage orchestrator that automates the
+deployment, configuration, and management of [Ceph](./ceph.md) storage clusters
+within Kubernetes environments. Built as a Kubernetes operator, Rook extends
+Kubernetes with custom resource definitions (CRDs) that allow administrators to
+define and manage Ceph clusters using native Kubernetes APIs and tools.  
+
+Rook eliminates much of the operational complexity traditionally associated
+with running Ceph by leveraging Kubernetes primitives for scheduling,
+self-healing, and scaling. When deployed, Rook runs as a set of pods within the
+Kubernetes cluster, managing the lifecycle of Ceph daemons (monitors, managers,
+OSDs, MDS, and RGW) as containerized workloads. It automatically handles tasks
+such as OSD provisioning from available storage devices, the management of the
+monitor quorum. 
+
+The system provides declarative configuration through YAML manifests, enabling
+infrastructure-as-code practices for storage management. Administrators can
+define storage classes that map to Ceph pools, allowing applications to
+dynamically provision persistent volumes for block storage (RBD), shared file
+systems (CephFS), or object storage (RGW) through standard Kubernetes
+mechanisms.  
+
+Rook continuously monitors cluster health and automatically responds to
+failures by restarting failed daemons, replacing unhealthy OSDs, and
+maintaining desired state as defined in the cluster specifications. It
+integrates with [Kubernetes](./cluster.md) monitoring and logging systems,
+providing visibility into storage operations alongside application workloads.
