+### mapHover
+
+Optional configuration object to customize the behavior of hover tooltips on the map. 
+The following properties are supported:
+
+| Property           | Meaning   | Example |
+|--------------------|:---------:|---------|
+| delay              | Timespan in milliseconds, by which displaying the tooltip is deferred after the mouse pointer rests. Defaults to `150`. | `"delay": 150`
+| hideOnMousemove    | Hide the tooltip when the mouse cursor is moved. Defaults to `false`. | `"hideOnMousemove": false`
+| hoverOverlay       | ID of a custom map overlay to use as a default display when a feature of the layer is hovered. Declaration of the `hoverOverlay` property on a mapLayer level takes precedence. For more information on how to implement a map overlay see the [reusable components](reusable-components?id=map-overlay) section. Defaults to Wegue's default tooltip `wgu-hover-tooltip` |  `"hoverOverlay": "my-custom-overlay"`
+
+Example:
+
+```json
+"mapHover":
+    {
+      "delay": 150,
+      "hideOnMousemove": false,
+      "hoverOverlay": "my-custom-overlay"

 ### lang
 
 Wegue comes with multi-language support and currently supplies 2 language packs for English (`en`) and German (`de`). Languages supported by the application can be configured via the `lang` property. Wegue will automatically detect the users preferred languages from the browser settings and choose the most appropriate match. If no languages are configured, Wegue will default to English.
