 ## Basic Usage
 
+Obligatory traffic light example:
+
 ```js
 import { createMachine } from "fsm";
 
-const light = createMachine({
-  data: { brightness: 0 },
-  states: {
-    off: 1,        // initially active
-    on: 0,
-    dimming: 0
-  },
+const trafficLight = createMachine({
+  states: { green: 1, yellow: 0, red: 0 },
   transitions: [
-    {
-      from: "off",
-      to: "on",
-      when: ctx => ctx.get("brightness") > 0
-    },
-    {
-      from: "on", 
-      to: "dimming",
-      when: ctx => ctx.get("brightness") < 50
-    }
+    { from: "green",  to: "yellow" },
+    { from: "yellow", to: "red" },
+    { from: "red",    to: "green" }
   ]
 });
 
-light.data.brightness = 75;
-light.step(); // evaluates transitions
-console.log(light.has("on")); // true
+// cycle through lights
+trafficLight.step();
+console.log(trafficLight.state); // ['yellow']
+
+trafficLight.step();
+console.log(trafficLight.state); // ['red']
+
+trafficLight.step();
+console.log(trafficLight.state); // ['green']
 ```
