Is the a dev guide to writing cromwell backends?

I'm trying to figure out what would be involved in adding a new backend to Cromwell. I haven't been able to find any dev guidelines on this topic. Is there maybe a class or trait that encompasses the interface? I'd appreciate any pointers.

Hi @mathias1 , it isn't super straightforward atm but if you are still interested, start w/ "supportedBackends" directory in the source. The Google v1alpha2 is the oldest and most mature and thus is the best place to start.
Thanks! I'll start there.
