In this appendix, we'll try to gather as much extra information as possible for those willing to go further from this point.
Even though we covered a lot of ground in this book, the Play! Framework 2 hasn't been covered entirely; there are yet some places to be discovered that wouldn't fit in this book—most of them are for advanced users, and some more specific to Scala.
This appendix will relate information about the following topics:
Play's features and internals that weren't covered
Features that were covered, but roughly or quickly introduced
Advanced features to ignite interest
Play's ecosystem
Play's communities—interesting blogs and groups
