+## Replaceable Components
+
+There is a list of components that you can replace at runtime.
+
+Create a new component that you want to use instead of the ABP component. Add that component to `declarations` and `entryComponents` in the `AppModule`.
+
+Then, open the `app.component.ts` and dispatch the `AddReplaceableComponent` action to replace your component with an ABP component as shown below:
+
+```ts
+import { ..., AddReplaceableComponent } from '@abp/ng.core';
+export class AppComponent implements OnInit {
+  constructor(..., private store: Store) {}
+
+  ngOnInit() {
+    this.store.dispatch(
+      new AddReplaceableComponent({
+        component: YourNewRoleComponent,
+        key: 'Identity.RolesComponent',
+      }),
+    );
+    //...
+  }
+}
+```
+
+An example:
+![Example Usage](./images/inaction.gif)
+
+> You can use `getAll` and `getComponent('Component Key')` selectors to get all replaceable components or just one of them by key.
+
