+
+You can delete multiple documents in a collection by calling the ``delete()`` method on an
+object collection or a query builder.
+
+To delete multiple documents, pass a query filter to the ``where()`` method. Then, delete the
+matching documents 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 documents from the ``movies`` collection that match a query filter
+- Prints the number of deleted documents
+
+The example calls the following methods on the ``Movie`` model:
+
+- ``where()``: matches documents in which the value of the ``year`` field is less than or
+  equal to ``1910``.
+- ``delete()``: deletes the retrieved documents. This method returns the number of documents
+  that were successfully deleted.
