+  View the real-time state and health of application resources.
+---
+
+
+`piped` continuously observes the resources of deployed applications running in your cluster.
+It reports their current state and health to the control plane, where the information is displayed in real time.
+
+This allows you to quickly understand:
+
+- What resources are currently running
+- Whether those resources are healthy
+- The overall health of the application
+
+## What is monitored
+
+For each application, `piped` tracks the live state of all related resources and components, including their metadata and health status.
+
+The application live state includes:
+
+- **Resource graph:**
+  A visual graph showing all application resources and components.
+  Each node represents a resource and displays:
+  - Resource metadata
+  - Current health status
+
+- **Application health status:**
+  The application is considered **`HEALTHY`** only when **all** of its resources and components are marked `HEALTHY`.
+
+## Viewing live state
+
+The live state is shown on the **Application Details** page in the control plane.
+
+- The graph updates automatically as resource states change.
+- This view reflects the actual state of resources in the cluster.
+
+## Inspecting a resource
+
+Clicking a resource or component node opens a panel on the right side of the screen.
+
+The panel shows detailed information about the selected resource, helping you investigate its configuration and health further.

+  Learn how to cancel a running deployment using the Control Plane.
+---
+
+A running deployment can be cancelled from web UI at the deployment details page.
+
+## Canceling a Deployment
+
+When you cancel an active deployment, PipeCD can automatically execute a rollback to the previous stable version if rollback is enabled in your application configuration.
+
+### Rollback Options
+
+You have two ways to control rollback behavior when canceling a deployment:
+
+1. **Automatic Rollback**: If enabled in the application configuration, rollback executes automatically after cancellation.
+
+2. **Manual Selection**: Click the dropdown arrow (`▼`) next to the `CANCEL` button in the web UI to explicitly choose whether to rollback or not.
