+Another alternative (if for example your `Enum` cant extend `PlayEnum` or `PlayFormFieldEnum`) is to create an implicit `Format`
+and bring it into scope using Play's `of`, i.e.
+
+```scala
+import play.api.data.Form
+import play.api.data.Forms._
+
+object Formats {
+  implicit val greetingFormat = enumeratum.Forms.format(Greeting)
+}
+
+object GreetingForm {

+      )(Data.apply)(Data.unapply)
+    )
+
