We are continually striving to improve Zen, to make it an even more valuable resource for the CoderDojo community.
The current issues with Zen are kept maintained here. If you wish to develop Zen, you can start here.
By being open-source, Zen evolve through its contributors, have a look at https://github.com/CoderDojo/cp-local-development on how to set up Zen locally
Even if you're not somebody with technical skills, you can contribute by completing the translations @niccokunzmann made a clear video on how to do so :)
