     the given `alpineState` variable.
     This state is a `AlertState`, as defined in `moderation-alert-index.ts`
 
-    Example :
+    This comes in three flavours :
+    - You can pass the `News` object itself to the macro.
+      In this case, if `request.user` can moderate news,
+      it will perform an additional db query to know if it is a recurring event.
+    - You can also give only the news id.
+      In this case, a server request will be issued to know
+      if it is a recurring event.
+    - Finally, you can pass the name of an alpine variable, which value is the id.
+      In this case, a server request will be issued to know
+      if it is a recurring event.
+
+    Example with full `News` object :
     ```jinja
     <div x-data="{state: AlertState.PENDING}">
       {{ news_moderation_alert(news, user, "state") }}
     </div>
     ```

+    ```jinja
+    <div x-data="{state: AlertState.PENDING}">
+      {{ news_moderation_alert(news.id, user, "state") }}

+      {{ news_moderation_alert("newsId", user, "state") }}
+    </div>

     Args:
-        news: The `News` object to which this alert is related
+        news: (News | int | string)
+          Either the `News` object to which this alert is related,
