 While the bulk of this code is in production across various Walmart systems, the [documentation](DOCUMENTATION.md) is very much a work in progress (ideally there'd be a nice [summary of various projection patterns](https://github.com/jet/propulsion/issues/21), but also much [broader information discussing the tradeoffs implied in an event-centric system as a whole](https://github.com/ylorph/The-Inevitable-Event-Centric-Book/issues)
