+
+You can delete a document in a collection by retrieving a single Eloquent model and calling
+the ``delete()`` method, or by calling ``delete()`` directly on a query builder.
+
+To delete a document, pass a query filter to the ``where()`` method, sort the matching documents,
+and call the ``limit()`` method to retrieve only the first document. Then, delete this matching
+document by calling the ``delete()`` method.
+
+Example
+-------
+
+This usage example performs the following actions:
+
+- Uses the ``Movie`` Eloquent model to represent the ``movies`` collection in the
+  ``sample_mflix`` database
+- Deletes a document from the ``movies`` collection that matches a query filter
+
+The example calls the following methods on the ``Movie`` model:
+
+- ``where()``: matches documents in which the value of the ``title`` field is ``'Quiz Show'``
+- ``orderBy()``: sorts matched documents by their ascending ``_id`` values
+- ``limit()``: retrieves only the first matching document
+- ``delete()``: deletes the retrieved document
