+# Signals
+
+Below are the signals that are sent by or during the use of django-components.
+
+## template_rendered
+
+Django's [`template_rendered`](https://docs.djangoproject.com/en/5.1/ref/signals/#template-rendered) signal.
+This signal is sent when a template is rendered.
+
+Django-components triggers this signal when a component is rendered. If there are nested components,
+the signal is triggered for each component.
+
+Import from django as `django.test.signals.template_rendered`.
+
+```python
+from django.test.signals import template_rendered
+
+# Setup a callback function
+def my_callback(sender, **kwargs):
+    ...
+
+template_rendered.connect(my_callback)
+
+class MyTable(Component):
+    template = """
+    <table>
+        <tr>
+            <th>Header</th>
+        </tr>
+        <tr>
+            <td>Cell</td>
+        </tr>
+    """
+
+# This will trigger the signal
+MyTable().render()
+```
