See the `anchor` prop for more details.<br/><br/> The default is the top middle of the image.<br/><br/> For ios, see the `calloutOffset` prop.
 | `flat` | `Boolean` |  | Sets whether this marker should be flat against the map true or a billboard facing the camera false.
 | `identifier` | `String` |  | An identifier used to reference this marker at a later date.
-| `rotation` | `Float` |  | A float number indicating marker's rotation angle.
+| `rotation` | `Float` |  | A float number indicating marker's rotation angle, in degrees.
 | `draggable` | `<null>` |  | This is a non-value based prop. Adding this allows the marker to be draggable (re-positioned).
