+## Version 5 Update
+
+Version 5 changes the API from a driver to a main wrapper.

+```ts
+import xs from 'xstream';
+import {run} from '@cycle/run';
+import {makeDOMDriver} from '@cycle/dom';
+import {makeHistoryDriver} from '@cycle/history';
+import {routerify} from 'cyclic-router';
+import switchPath from 'switch-path';
+
+function main(sources) {
+  const match$ = sources.router.define({
+    '/': HomeComponent,
+    '/other': OtherComponent
+  });
+  
+  const page$ = match$.map(({path, value}) => {
+    return value(Object.assign({}, sources, {
+      router: sources.router.path(path)
+    }));
+  });
+  
+  return {
+    DOM: page$.map(c => c.DOM).flatten(),
+    router: xs.of('/other'),
+  };
+}

+const app = routerify(main, switchPath);
+
+run(app, {
+  DOM: makeDOMDriver('#app'),
