+Text Elements
+=============
+
+Folium supports several ways to display text on maps.
+
+**1. DivIcon Labels**
+To add always-visible text labels on the map:
+
+.. code-block:: python
+
+    from folium import Map, Marker, DivIcon
+
+    m = Map(location=[40.7128, -74.0060], zoom_start=13)
+    Marker(
+        location=[40.7128, -74.0060],
+        icon=DivIcon(
+            icon_size=(150,36),
+            icon_anchor=(0,0),
+            html='<div style="font-size: 12pt; color : black">Hello World!</div>',
+        )
+    ).add_to(m)
+    m.save("map.html")
+
+**2. Tooltip and Popup Text**
+
+Use tooltips for hover text or popups for clickable text.
