+
+In order to enable localisation support you will need to create a `/resources/i18n/en.json` file
+and register its parent `i18n` folder with your component or application module.
+
+For example:
 
 ```ts
-class MainApplication {
+import { TRANSLATION_PROVIDER } from 'ng2-alfresco-core';
-    constructor(translateService: TranslationService) {
+
-        translateService.addTranslationFolder('app', 'resources');

+            }
+        }
+    ]
+})
 ```
 
-Service also allows changing current language for entire application.
+Note: the `source` property points to the web application root, please ensure you have webpack settings to copy all the i18n files at compile time.
-Imagine you got a language picker that invokes `onLanguageClicked` method:
+
+```text
+index.html
+assets/ng2-alfresco-core/i18n/en.json
+...
+```
+
+You can register as many entries as you would like.
+
+### Switching languages
+
+Depending on your application, you may want to have buttons or dropdown menus to allow language selection for the end users.
+
+You can use `TranslationService` to switch languages from your code based on input events of your choice:
 
 ```ts
 class MyComponent {

     }
 }
 ```
 
-It is also possible providing custom translations for existing components by overriding their resource paths:
-
-```ts
-class MyComponent {
-    constructor(private translateService: TranslationService) {
-        translateService.addTranslationFolder(

-        );
-    }

-
-**Important note**: `addTranslationFolder` method redirects **all** languages to a new folder, you may need implementing multiple languages 
-or copying existing translation files to a new path.
