-6.  Create a new _Component_ named `my-counter` in the `app` folder. Inject the `Store` service into your component to dispatch the counter actions, and use the `select` operator to _select_ data from the state.
+6.  Create a new file called `my-counter.component.ts` in the `app` folder that will define a new component called `MyCounterComponent`. This component will render buttons that allow the user to change the count state.

-Update the `MyCounterComponent` template with buttons to call the increment, decrement, and reset methods. Use the async pipe to subscribe to the _count$_ observable.
+7.  Add the new component to your AppModule's declarations and declare it in the template:
 
-<code-example header="src/app/my-counter/my-counter.component.html" path="store/src/app/my-counter/my-counter.component.html">
+<code-example header="src/app/app.component.html" path="store/src/app/app.component.html" region="counter">
 </code-example>
 
-Update the `MyCounterComponent` class with a selector for the _count_, and methods to dispatch the Increment, Decrement, and Reset actions.

-7.  Add the `MyCounter` component to your `AppComponent` template.
+8.  Inject the store into `MyCounterComponent` and connect the `count$` stream to the store's `count` state. Implement the `increment`, `decrement`, and `reset` methods by dispatching actions to the store.

 And that's it! Click the increment, decrement, and reset buttons to change the state of the counter.
