+
+You can update a document in a collection by retrieving a single document and calling
+the ``update()`` method on an Eloquent model or a query builder.
+
+Pass a query filter to the ``where()`` method, sort the matching documents, and call the
+``first()`` method to retrieve only the first document. Then, update this matching document
+by passing your intended document changes to the ``update()`` method.
+
+Example
+-------
+
+This usage example performs the following actions:
+
+- Uses the ``Movie`` Eloquent model to represent the ``movies`` collection in the
+  ``sample_mflix`` database.
+- Updates 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 ``'Carol'``.
+- ``orderBy()``: sorts matched documents by their ascending ``_id`` values.
+- ``first()``: retrieves only the first matching document.
+- ``update()``: updates the value of the ``imdb.rating`` nested field to from ``6.9`` to
+  ``7.3``. This method also updates the ``imdb.votes`` nested field from ``493`` to ``142000``.
