 ### Setup
 
 1. Use npm to install the bindings:
-```
-npm install @ngrx/router-store --save
-```
+  ```
+  npm install @ngrx/router-store --save
+  ```
 
 2. Use the `routerReducer` when providing `Store`:
-```ts
-import { provideStore } from '@ngrx/store';
-import { routerReducer } from '@ngrx/router-store';
-
-
-export const storeProvider = provideStore({
-  // Your reducers go here,
-  router: routerReducer
-});
-```
+  ```ts
+  import { provideStore } from '@ngrx/store';
+  import { routerReducer } from '@ngrx/router-store';
+  
+  
+  export const storeProvider = provideStore({
+    // Your reducers go here,
+    router: routerReducer
+  });
+  ```
 
 3. Install the bindings providers after you setup the router providers:
-```ts
-import { connectRouterToStore } from '@ngrx/router-store';
-
-bootstrap(App, [
-  storeProvider,
-  provideRouter(routes),
-  connectRouterToStore()
-]);
-```
+  ```ts
+  import { connectRouterToStore } from '@ngrx/router-store';
+  
+  bootstrap(App, [
+    storeProvider,
+    provideRouter(routes),
+    connectRouterToStore()
+  ]);
+  ```
