Contribute

Orbital is open source, open data and open to people, in the sense Open³ gives those words. Feedback, questions, suggestions and code are all welcome.

Talk

The conversation happens on Discord. Say hello, ask a question, tell us what is unclear, or bring a scenario you want modeled.

Code

Everything is on GitHub under orbitalfoundation. Issues and pull requests are welcome on any repository. The two packages most in use are the bus and Volume. The bus specification ends with a list of open questions, and the Volume README with a list of unresolved design tensions. Either is a good place to start.

The primer

Simulate the World is a working draft and it improves with readers. Argue with a chapter, point out a case study we missed, or tell us where the argument loses you. The closing chapter credits the people who helped.

Models

If you want to build a playable model of a place or a question, come and talk. The Futures Desk indexes pieces built this way, and the bus and Volume are what they run on.
