+### Single Argument Property Creator annotationless support
+
+This module also adds support for deserializing single property value objects when using parameter names module:
+
+```java
+class Foo {
+    private final Bar bar;
+
+    Foo(Bar bar) {
+        this.bar = bar;
+    }
+}
+```
+
+without any additional configuration or annotations.
