 ## Use case
 
-Multi-use and/or international applications benefit from the ability to change a basemap's style or localize the basemap. For example, an application used for ecological surveys might include navigation functionality to guide an ecologist to a location and functionality for inputting data. When traveling, a user is likely to benefit from a map with a style that emphasizes the transport infrastructure (e.g. `ArcGIS Navigation`). However, during surveys a user is likely to benefit from a map with a style that highlights features in the terrain (e.g. `ArcGIS Terrain`). Implementing a basemap gallery with customization options in an application gives a user the freedom to select a basemap with a style and features (e.g. language of labels) suitable for the task they are undertaking. Making the basemap gallery dynamic ensures the latest customization options are automatically included.

 ## How to use the sample
 
-When launched, this sample displays a map containing a button that, when pressed, displays a gallery of all styles available in the basemap styles service. Selecting a style results in the drop-down menus at the base of the gallery becoming enabled or disabled. A disabled menu indicates that the customization cannot be applied to the selected style. Once a style and any desired customizations have been selected, pressing `Load` will update the basemap in the map view.
+Press "Basemap" to display a gallery of all styles available in the basemap styles service. Select a style using the "Style" picker. Select a language or language strategy using the "Language" picker. Optionally selected a worldview using the "Worldview" picker. Disabled pickers indicate that the customization cannot be applied to the selected style.
 
 ## How it works
 
-* Instantiate and load a `BasemapStylesService` object.
-* Get the `BasemapStylesServiceInfo` object from `BasemapStylesService.info()`.
-* Access the list of `BasemapStyleInfo` objects using `BasemapStylesServiceInfo.stylesInfo()`. These `BasemapStyleInfo` objects contain up-to-date information about each of the styles supported by the Maps SDK, including:
-  * `styleName`: The human-readable name of the style.
-  * `style`: The `BasemapStyle` enumeration value representing this style in the Maps SDK.
-  * `thumbnail`: An image that can be used to display a preview of the style.
-  * `languages`: A list of `BasemapStyleLanguageInfo` objects, which provide information about each of the specific languages that can be used to customize labels on the style.
-  * `worldview`: A list of `Worldview` objects, which provide information about each representation of a disputed boundary that can be used to customize boundaries on the style.

 ## Additional information
 
-This sample demonstrates how to implement a basemap gallery using the Maps SDK. The styles and associated customization options used for the gallery are retrieved from the [basemap styles service](https://developers.arcgis.com/rest/basemap-styles/). A ready-made basemap gallery component is also available in the toolkit's provided with each SDK. To see how the ready-made basemap gallery toolkit component can be integrated into a Maps SDK application refer to the `Set Basemap` sample.
