 # Stent
 
-Container for finite state machines or in other words - a tool for state management based on state machines.
+Stent is combining the ideas of redux with the concept of state machines.

+## A few words about state machines
 
-The library is available as a [npm module](https://www.npmjs.com/package/stent) so `npm install stent` will do the job. There's also a standalone version [here](./standalone/stent.js) (only core functionalities) which you can directly add to your page.
+State machine is a mathematical model of computation. It's an abstract concept where the machine may have different states but at a given time fulfills only one of them. It accepts input and based on that (plus its current state) transitions to another state. Isn't it sounds familiar? Yes, it sounds like a front-end application. That's why this model/concept applies nicely to UI development.
 
-## A few words about state machines
+*Disclaimer: there are different types of state machines. I think the one that makes sense for front-end development is [Mealy state machine](https://en.wikipedia.org/wiki/Mealy_machine).*
