 ## Tracking Specific Components
 
-You can let Sentry know which components to track specifically by passing the `sentry-label` prop to them. If Sentry detects a component with a `sentry-label` within a touch's component tree, it will be logged on the dashboard as having occurred in that component. If Sentry cannot find a component with the label, Sentry will fall back to the `labelName` prop if specified, or else use `displayName`.
+You can let Sentry know which components to track specifically by passing the `sentry-label` prop to them. If Sentry detects a component with a `sentry-label` within a touch's component tree, it will be logged on the dashboard as having occurred in that component.
+
+For each component in the touch path, the SDK extracts a **label** and a **name**. The breadcrumb message uses the label if any component in the path has one; otherwise it falls back to the root component's name.
+
+The **label** is determined by the first available value from:
+
+1. `sentry-label` prop
+2. Custom `labelName` prop (if configured on the boundary)
+3. `accessibilityLabel` prop
+4. `aria-label` prop
+5. `testID` prop
+
+The **name** comes from the Babel plugin annotation (`data-sentry-component`) or `displayName`. See [Component Names](/platforms/react-native/integrations/component-names/) for details.
+
+This means apps that use accessibility labels or test IDs get meaningful touch breadcrumbs automatically, without any extra configuration.
