 ## Use case
 
-In many applications, geoelements are represented by a symbol composed of a number of components. For example, individual elements of a water infrastructure network, such as valves, nodes, or endpoints, will be represented on the map as symbols of the same base shape, with additional components to represent their characteristics, such as technical specifications. 
+In many applications, geoelements are represented by a symbol composed of a number of components. For example, individual elements of a water infrastructure network, such as valves, nodes, or endpoints, will be represented on the map as symbols of the same base shape, with additional components or colors added to represent their unique characteristics, such as technical specifications. 
 
 While each of these symbols can be created from scratch, a more convenient workflow is to author them using ArcGIS Pro and store them in a mobile style file (.stylx). ArcGIS Runtime can read symbols from a mobile style, and you can modify and combine them as needed in your app.
