+This extension has been created to integrate finite state machine in [BehaviourBuilder](../tgbotapi.extensions.behaviour_builder/README.md).
+In case you wish to use some custom store for steps (states), you may extend `StatesManager` or use `DefaultStatesManager`
+with custom `DefaultStatesManagerRepo`. See [Examples repo](https://github.com/InsanusMokrassar/TelegramBotAPI-examples/tree/master/FSMBot)
+to get more info and see how it works on base level
