 ## How to use the sample
 
-This sample showcases the workflow of configuring basemap style parameters by displaying a basemap with labels in different languages and launches with a `Viewpoint` set over Bulgaria, Greece, and Turkey, as they use three different alphabets: Cyrillic, Greek, and Latin, respectively. By default, the `BasemapStyleLanguage` is set to `local` which displays all labels in their corresponding local language. This can be changed to `global`, which displays all labels in English. The `specific` option sets all labels to a selected language and overrides the `BasemapStyleLanguage` settings.

 ## About the data
 
-The main data for this sample is the basemap style which includes basemaps that support both language localization and global language setting. The supported languages, along with their language code, can be found in the [API's documentation](https://developers.arcgis.com/rest/basemap-styles/#languages).
