+### Experimental Features
+Since version 2.10.0, a new experimental feature is available. If you enable `experimentalInterfaces`, Fixture will attempt to find implementations for an interface (or non-abstract subclasses of an abstract class) on your classpath and create those instead of wrapping the interface with a proxy. If no suitable implementation is found, the proxy will be created as a fallback.
+
+```java
+@Test
+void canCreateGenericObjectFromInterfaceWithMismatchingNumberOfTypeParameters() {
+    var fixture = new Fixture(Configuration.configure().experimentalInterfaces(true));
+
+    var result = fixture.create(new SpecimenType<GenericInterfaceTUWithGenericImplementationU<String, Integer>>() {});
+
+    assertThat(result).isInstanceOf(GenericInterfaceTUWithGenericImplementationUImpl.class);
+    assertThat(result.publicField).isInstanceOf(Integer.class);
+    assertThat(result.getT()).isInstanceOf(String.class);
+    assertThat(result.getU()).isInstanceOf(Integer.class);
+}
+```
+This setting is not supported with annotations. However, to enable this feature globally, place a file `javafixture/com.github.nylle.javafixture.experimetalInterfaces` on your classpath with the content "enabled". To disable it, either delete the file or change the content to something else, e.g. "disabled".
