+Scala3 support
+--------
+The Scala3 version is meant to be compatible with Scala2 where possible. Currently there is a few missing features:
+* wire from parent scope https://github.com/lampepfl/dotty/issues/13105
+* wire from imports https://github.com/lampepfl/dotty/issues/12965
+* wire in pattern matching
+* `wiredInModule` 
+* `@Module`
+
+For full list of incompatibilities take a look at `tests/src/test/resources/test-cases` and `util-tests/src/test/resources/test-cases` 
+
+
+
 There's also a [G8 template available](https://github.com/lloydmeta/ctdi-play.g8) which can be used with `sbt new`.
