+## Component Lifecycle
+
+Every Effect-FC component instance exposes an Effect `Scope`. Effects that need
+`Scope.Scope` can use that component scope to register finalizers, fork scoped
+work, or acquire scoped resources.
+
+The component scope is created when React mounts the component and closes when
+React unmounts it. When the scope closes, Effect runs the finalizers registered
+inside that scope.
+
+```tsx title="src/MountedMessageEffect.tsx"
+import { Console, Effect } from "effect"
+import { Component } from "effect-fc"
+
+export const MountedMessageEffect = Component.make("MountedMessage")(
+  function* () {
+    yield* Component.useOnMount(() =>
+      Effect.gen(function* () {
+        yield* Console.log("MountedMessage mounted")
+        yield* Effect.addFinalizer(() =>
+          Console.log("MountedMessage unmounted"),
+        )
+      }),
+    )
+
+    return <p>This component owns an Effect scope.</p>
+  },
+)
+```
+
+Use `Component.useOnMount` for work that should run once for the component
+instance. Use `Component.useOnChange` when the scoped work should be recreated
+when dependencies change.
+
+```tsx
+const UserPanelEffect = Component.make("UserPanel")(
+  function* (props: { readonly userId: string }) {
+    const user = yield* Component.useOnChange(
+      () => fetchUser(props.userId),
+      [props.userId],
+    )
+
+    return <p>{user.name}</p>
+  },
+)
+```
+
+In this example, changing `userId` closes the previous dependency scope before
+creating a new one. Unlike `useOnMount`, `useOnChange` does not expose the component's root scope directly.
+It creates and provides its own scope for that dependency window. Some other Effect-FC hooks
+follow the same pattern when they need a lifecycle that is narrower than the
+whole component instance.
+
 ## Use Services
 
 Components can yield Effect services directly. Define services with Effect,
