+## Use cases
+
+Below are some common or advanced use cases when using a map.
+
+### Customize the marker
+
+A common use case is to customize the marker. You can listen to the `ux:map:marker:before-create` event to customize the marker before it is created.
+
+Assuming you have a map with a custom controller:
+```twig
+{{ render_map(map, {'data-controller': 'my-map' }) }}
+```
+
+You can create a Stimulus controller to customize the markers before they are created:
+```js
+// assets/controllers/my_map_controller.js
+import {Controller} from "@hotwired/stimulus";
+
+export default class extends Controller
+{
+    connect() {
+        this.element.addEventListener('ux:map:marker:before-create', this._onMarkerBeforeCreate);
+    }
+
+    disconnect() {
+        // Always remove listeners when the controller is disconnected
+        this.element.removeEventListener('ux:map:marker:before-create', this._onMarkerBeforeCreate);
+    }
+
+    _onMarkerBeforeCreate(event) {
+        // You can access the marker definition and the google object
+        // Note: `definition.rawOptions` is the raw options object that will be passed to the `google.maps.Marker` constructor. 
+        const { definition, google } = event.detail;
+
+        // 1. To use a custom image for the marker 
+        const beachFlagImg = document.createElement("img");
+        // Note: instead of using an hardcoded URL, you can use the `extra` parameter from `new Marker()` (PHP) and access it here with `definition.extra`.
+        beachFlagImg.src = "https://developers.google.com/maps/documentation/javascript/examples/full/images/beachflag.png";
+        definition.rawOptions =  { 
+            content: beachFlagImg
+        }
+
+        // 2. To use a custom glyph for the marker
+        const pinElement = new google.maps.marker.PinElement({
+            // Note: instead of using an hardcoded URL, you can use the `extra` parameter from `new Marker()` (PHP) and access it here with `definition.extra`. 
+            glyph: new URL('https://maps.gstatic.com/mapfiles/place_api/icons/v2/museum_pinlet.svg'), 
+            glyphColor: "white",
+        });
+        definition.rawOptions = {
