 # Coordinator
 
 The Coordinator is MarbleRun's control plane.
+Conceptually, it operates as trusted controller in your confidential deployment.
+It securely holds the deployment's state, including the [manifest](../features/manifest.md) and the defined [secrets](../features/secrets-management.md).
+Based on the manifest, the Coordinator uses [remote attestation](../features/attestation.md) to authenticate the application's enclaves.
+
+
+
+## API and Configuration
+
 It communicates with the Marble's data plane through gRPC and provides an HTTP REST interface on the client-side.
 The Coordinator can be configured with several environment variables:

+# Marbles
+
+Marbles are MarbleRun's data planes and run your application code in secure enclaves.
+Marbles communicate with the Coordinator via gRPC over TLS.
+MarbleRun [supports multiple enclave runtimes](../features/runtimes.md) as the data plane.
+See the [Add a Service](../workflows/add-service.md) section on how to build and configure an enclave as Marble.
