That's good to hear that you're working on a ship mod - looking forwards to seeing it.

Yes, I have been working on a ship mod to use as an example.

Leebee 18 Jul @ 6:05am

Please can you add some info about how to create a new mod locally as well as how to add a new ship in the mod manifest?

Thanks!
