+## Property Titles
+
+Property names are defined by the schema constructor argument, while `title()` is metadata and only included when it differs from the property name:
+
+```php
+$schema = Schema::object()
+    ->properties(
+        Schema::string('email')->title('Email Address')
+    );
+```
+
+```json

+    "properties": {
+        "email": {
+            "type": "string",
+            "title": "Email Address"
+        }
+    }
