+=== Known issues and limitations
+
+* Parallel build, hence `mvnd`, don't play well with `-rf` maven option at the monet. If you use the `-rf` maven option with `mvnd` you have no guarantee that all the modules will have been built (There are some improvements planned on this in the next `mvnd` releases).

 We're happy to improve `mvnd`, so feedback is most welcomed!
