+### How to Get a Specific Feature From the Store
+
+You can use the `getFeature` method of `ConfigStateService` to get a specific feature from the configuration state. Here is an example:
+
+```js
+// this.config is instance of ConfigStateService
+
+const isChatEnabled = this.config.getFeature("Chat.Enable");
+// 'en'
+```
+
 ### How to Get a Specific Permission From the Store
 
 You can use the `getGrantedPolicy` method of `ConfigStateService` to get a specific permission from the configuration state. For that, you should pass a policy key as parameter to the method.
