 # Finite
 
 Finite is a simple, pure Swift finite state machine. Only exlicitly allowed transitions between states are allowed, otherwise an error will be thrown.
-Version `2.0.0` supports Swift `2.2` and `3.0 Beta`, whereas Finite `3.x.x` only supports Swift `3.0`.

 It is possible to provide callbacks, that will be called once certain transitions will happen.
 
 ```swift
-machine.onTransitions(from: .Ready) {
+machine.onTransitions(from: .ready) {
     println("From Ready: show activity indicator")
 }
-machine.onTransitions(to: .Ready) {
+machine.onTransitions(to: .ready) {

 }

+machine.onTransitions(to: .saving) {
     println("To: save")
 }
 ```
 
 Once the `StateMachine` has been set up, you may trigger all transitions you have declared above.
 
 ```swift
-try machine.transition(to: .Saving) {
+try machine.transition(to: .saving) {
     println("Triggered: save")
 }
 
 // this will throw an error
-try machine.transition(to: .Fetching)
+try machine.transition(to: .fetching)
