+You can also pass array of criteria or callbacks to determine how to sort the collection values:

+```js
+const collection = collect([

+  { name: 'Chair', price: 100 },

+
+You can use multiple keys to sort. Keys are considered in the order they appear in the parameter.
+
+```js
+const collection = collect([
+  { name: 'Desk', price: 200 },
+  { name: 'Table', price: 200 },

+
+```js

+  { name: 'Bookcase', colors: ['Red', 'Beige', 'Brown'] },

+
+const sorted = collection.sortBy([(product, key) => product.colors.length]);

+//   { name: 'Desk', colors: ['Black', 'Mahogany'] },
+//   { name: 'Bookcase', colors: ['Red', 'Beige', 'Brown'] },

+
+You can also pass multiple callbacks of your own to determine how to sort the collection values:
+```js
+const collection = collect([
+  { name: 'Desk', colors: ['Black', 'Mahogany'] },
+  { name: 'Chair', colors: ['Black', 'Mahogany'] },

 #### `sortByDesc()`
 
 This method has the same signature as the `sortBy` method, but will sort the collection in the opposite order.
 
+#### `sortByMany()`
+
+The sortByMany method sorts the collection by the given key. The sorted collection keeps the original array keys, so in this example we'll use the values method to reset the keys to consecutively numbered indexes:
+
+
 #### `sortDesc()`
 
 This method will sort the collection in the opposite order as the `sort` method.
