+The logbook component provides a different perspective on the history of your house by showing all
+the changes that happened to your house in reverse chronological order.
+[See the demo for a live example](/demo/).
+
+To enable the logbook in your installation, add the following to your `configuration.yaml` file:
+
+```yaml
+# Example configuration.yaml entry
+logbook:
+```
+
+It is possible to add custom entries to the logbook by using the script component to fire an event.
+
+```yaml
+# Example configuration.yaml entry
+script:
+  add_logbook_entry:
+    alias: Add Logbook
+    sequence:
+      - event: LOGBOOK_ENTRY
+        event_data:
+          name: Kitchen
+          message: is being used
+          # Optional
+          entity_id: light.kitchen
+          domain: light
+```
