 It's very "work in progress". At the moment there's only one demo program.
 
+## Getting Help
+
+If you want to contact us you should join the [Rust Community
+Discord](https://discordapp.com/invite/aVESxV8) and ask in the `#gamedev`
+channel. `Ketsuban` is the wizard who knows much more about how it all works,
+and `Lokathor` is the fool who decided to write a crate and book for it.
+
+If it's _not_ a GBA specific question then you can also ask any of the few
+hundred other folks in the server as well.

 ## Other Works
