                         ClusterKit is an efficient clustering framework with the following features:
-                        - Native supports of MapKit, GoogleMaps and Mapbox.
+                        - Native supports of MapKit, GoogleMaps, Mapbox and YandexMapKit.
                         - Comes with 2 clustering algorithms, a Grid Based Algorithm and a Non Hierarchical Distance Based Algorithm. Other algorithms can easily be integrated.
                         - Annotations are stored in a QuadTree for efficient region queries.
                         - Cluster center can be switched to Centroid, Nearest Centroid, Bottom.
