+This recipe demonstrates how to use the `outlines` library to extract structured event details from a text message.
+We will extract the title, location, and start date and time from messages like the following:
+
+```plaintext
+Hello Kitty, my grandmother will be here, I think it's better to postpone
+our appointment to review math lessons to next Monday at 2pm at the same
+place, 3 avenue des tanneurs, one hour will be enough see you 😘
+```
+
+Let see how to extract the event details from the message with the MLX
+library dedicated to  Apple Silicon processor  (M series).
+
+```python
+--8<-- "docs/cookbook/extract_event_details.py"
+```
+
+The output will be:
+
+```plaintext
+Today: Saturday 16 November 2024 and it's 10:55
+```
+
+and the extracted event information will be:
+
+```json
+{
+  "title":"Math Review",
+  "location":"3 avenue des tanneurs",
+  "start":"2024-11-22T14:00:00Z"
+}
+```
+
+
+To find out more about this use case, we recommend the project developped by [Joseph Rudoler](https://x.com/JRudoler) the [ICS Generator](https://github.com/jrudoler/ics-generator)
