I recently discovered that codecombat is supporting Io as an programming language. As a big fan of the Io language I would like to try helping to advance the support of Io in codecombat. I guess I have to start getting myself familar with the build environment and Aether. As a start I will setup my build environment for Linux as described in https://github.com/codecombat/codecombat/wiki/Dev-Setup:-Linux. Any other pointers where I can read more details about changing and testing the transpilers.
