+### Dynamically change route
+
+You can dynamically change route from code by emitting inputs handled by [the history driver](http://cycle.js.org/history/docs/#historyDriver).
+
+```js
+function main(sources) {
+  // ...
+  const homePageClick$ = sources.DOM.select(".home").events("click");
+  const previousPageClick$ = sources.DOM.select(".previous").events("click");
+  const nextPageClick$ = sources.DOM.select(".next").events("click");
+  const oldPageClick$ = sources.DOM.select(".old").events("click");
+  const aboutPageClick$ = sources.DOM.select(".about").events("click");
+
+  return {
+    // ...
+    router: xs.merge(
+        // Go to page "/"
+        homePageClick$.mapTo("/"),
+
+        // Go back to previous page
+        previousPageClick$.mapTo({ type: "goBack" }),
+
+        // Go forward to next page
+        nextPageClick$.mapTo({ type: "goForward" }),
+
+        // Go back from 5 pages
+        oldPageClick$.mapTo({ type: "go", value: -5 }),
+
+        // Go to page "/about" with some state set to router's location
+        aboutPageClick$.mapTo({ pathname: "/about", state: { some: "state" } })
+    ),
+  };
+}
+```
