 Follow the instructions in the examples below to insert data into
 a collection and perform a sort and skip on the results of a query.
 Consider a collection containing documents that describe varieties of
-fruit. To insert this data into a collection, run the following
-operation:
+fruit:
 
 .. code-block:: javascript
 
-   await collection.insertMany([
+   [
       { "_id": 1, "name": "apples", "qty": 5, "rating": 3 },

       { "_id": 3, "name": "oranges", "qty": 6, "rating": 2 },
       { "_id": 4, "name": "avocados", "qty": 3, "rating": 5 },
-   ]);
+   ]
 
-Pass the following sort document to a read operation to ensure that the
-operation returns fruit documents with higher ratings before fruit
-documents with lower ratings:
+In the following example, we query the collection with a filter that
+matches all the documents and pass options that specifies ``sort`` and
+``skip`` commands as query options. The sort option specifies that fruit
+documents with higher ratings should be returned before ones with lower
+ratings. The skip option specifies that the first 2 documents should be

-In this case, the number ``-1`` tells the read operation to sort the
-fruit in descending order by rating. ``skip`` omits the first two
-matched documents in the sorted order. ``find()`` returns the following
-documents when this sort is used with an empty query:
+Since we specified that the first ``2`` documents should be skipped, the
+third and fourth highest rating documents are printed by the code snippet

+The ``sort`` and ``skip`` options can also be specified as methods chained to
+the ``find`` method. The following two commands are equivalent:

+   collection.find(query).sort({rating: -1}).skip(2);
