+func main() {
+
+  notify = notificator.New(notificator.Options{
+    DefaultIcon: "icon/default.png",
+    AppName:     "My test App",
+  })
+
+  notify.Push("title", "text", "/home/user/icon.png", notificator.UR_CRITICAL)
+}
+```
+
+TODO
+-----
+
+  * Add more options for different notificators.
