 * By assigning a value of `true` to the field, we defer to the model to infer the type for the field. To override that, we can always add a `type` property:
 
-```yaml
-MyProject\Models\Product:
-  fields:
-    onSale:
-      type: Boolean
-```
+    ```yaml
+    MyProject\Models\Product:
+      fields:
+        onSale:
+          type: Boolean
+    ```
 
 * The mapping of our field names to the `DataObject` property is case-insensitive. It is a
 convention in GraphQL APIs to use lowerCamelCase fields, so this is given by default.
