+This is my attempt in learning core principles behind [EventStore](https://github.com/EventStore/EventStore), starting from [Staged Event-Driven Architecture](http://en.wikipedia.org/wiki/Staged_event-driven_architecture). 
 
 I'm taking core bits from ES and rewrite them from scratch, while focusing on simplicity.
 
 So far we've got:
 
 * In-Memory Message Bus (pipes)
 * Generic Finite State Machine (with builder)
-* Node controller with wired custom state machine
+* Node controller with wired custom state machine and a few states.
 * In-memory timer service (for callbacks, async IO and timeouts)
 * Hello World service, that properly initializes, shuts down and sends Hello to itself once every few seconds
