+The type can be sorted using the `order` field in the query:
+
+```graphql
+query {
+  users(order: [{name: ASC}]) {
+    name
+    address {
+      street
+    }
+  }
+}
+```
+
+Properties of nested objects can be sorted as well:
+
+```graphql
+query {
+  users(order: [{address: {street: ASC}}]) {
+    name
+    address {
+      street
+    }
+  }
+}
+```
+
+Note that it is possible to sort on a field and then by another field:
+
+```graphql
+query {
+  users(order: [{name: ASC}, {address: {street: DESC}}]) {
+    name
+    address {
+      street
+    }
+  }
+}
+```

 # Customization
 
 Under the hood, sorting is based on top of normal Hot Chocolate input types. You can easily customize them with a very familiar fluent interface. The sorting input types follow the same `descriptor` scheme as you are used to from the normal input types. Just extend the base class `SortInputType<T>` and override the descriptor method.
